A doxorubicin and siRNA coloaded nanolamellar hydroxyapatite/PLGA electrospun scaffold as a safe antitumor drug delivery system

To circumvent the severe cytotoxicity and drug resistance of chemotherapeutics in cancer chemotherapy, we rationally designed an electrospun nanofibrous delivery system for the codelivery of the doxorubicin (DOX) and small interfering ribonucleic acid (siRNA) to improve antitumor activity and mitigate DOX drug resistance. DOX was intercalated into nanolamellar hydroxyapatite (LHAp), which was incorporated into electrospun poly(lactic-co-glycolic acid) (PLGA) nanofibers, and finally, the DOX-intercalated LHAp/PLGA scaffold was coated with polydopamine (PDA) followed by immobilization with siRNA/polyethyleneimine (PEI) complexes. Benefiting from its intrinsic degradability, the scaffold demonstrated pH-responsive release behavior, leading to the simultaneous delivery of DOX and siRNA. Consequently, the codelivery scaffold demonstrated enhanced therapeutic efficiency in vitro and in vivo compared with the scaffold loaded with single drug due to the combined effects of DOX and siRNA and did not show toxicity or side effects in mice. Therefore, it is a safe and effective strategy for preventing postsurgical tumor recurrence.

Electrospun poly(ST-Co-AC)/Co-ZIF-67@Chitosan composite nanofibers as a sorbent with superior reusability for pesticide residues analysis in food samples

Pollution caused by pesticides have attracted huge attention, and it is of a great significance to develop sensitive methods for trace monitoring these analytes in complicated matrices. Herein, the composite of styrene acrylonitrile copolymer p(St-Co-AC)/zeolitic based metal–organic frameworks (Co-ZIF-67)/Chitosan (CS) electrospun nanofibers was fabricated by using an electrospinning approach. The resultant composite nanofibers were characterized to apply as a novel adsorbent for pipette tip micro solid-phase extraction (PT- μSPE) of four pesticides prior to GC-FID analysis. Incorporating Co-ZIF-67@Chitosan into p(ST-Co-AC) results in increasing the porosity features and surface area of the nanofibers. The effect of different main parameters on extraction efficiency was evaluated. Under the optimal conditions, linearity ranges were 1.5–2000.0 ng mL−1 for ethofumasate, 2.0–2000.0 ng mL−1 for ametryn and propazine, and 3.0–2000.0 ng mL−1 for tribenuron-methyl (R2 = 0.9951–0.9997). The LODs (according to S/N = 3) were calculated in the range of 0.5 to 1.0 ng mL−1.The relative standard deviations (RSDs) were obtained between 5.1 % – 6.1 % (intra-day, n = 5) and 5.6 %–6.4 % (inter-day, n = 3) for three sequential days. The developed method was investigated in food samples including apple, tomato, honey, and milk, and achieved recoveries (88.1–95.2 %) indicated that the fabricated sorbent could be a promising composite for the pre-concentration of pesticides in various matrices.

Controlled Release of Gentamicin from Electrospun Poly(Vinyl Alcohol)/Gelatin Nanofibers: The Effect of Crosslinking Time Using Glutaraldehyde Vapor

AbstractIn this study, polyvinyl alcohol (PVA), gelatin (GEL) and gentamicin (GEN) were used and 13PVA/0.5GEL/GEN nanofibers were fabricated with the electrospinning method. These nanofibers were crosslinked chemically with glutaraldehyde (GA) at different time intervals (2, 3, 4, 5, 5.5 and 6 h) to observe the crosslinking effect on the properties of the nanofibers. Morphological analysis reported that as the crosslinking time increased, the nanofiber diameters also increased from 369.26 nm (non‐crosslinked) to 447.72 nm (6 h/crosslinking), respectively. The thermal characterization results demonstrated that crosslinking with different times noticeably shifted the thermal points.The tensile testing results proved that application of crosslinking enhanced the mechanical strength of the nanofibers from 3.31 MPa (non‐crosslinked) to 5.8 MPa (5.5 h/crosslinking), respectively. The GEN release profiles from the nanofibers showed similar behaviors under crosslinking and indicated that the crosslinking time did not have a significant effect on the amount of the GEN released.

Fabrication and Characterization of Electrospun Poly(Caprolactone)/Tannic Acid Scaffold as an Antibacterial Wound Dressing.

Antibacterial wound dressings are promising materials to treat infected skin wounds, which greatly affect the wound-healing process. In this study, tannic acid (TA), a natural antibacterial agent, was successfully loaded by electrospinning into poly(caprolactone) (PCL) fibers in a high concentration. It is suggested that the addition of TA was beneficial for producing uniform and continuous PCL nanofibers. Hydrogen bonds existed between the PCL and TA molecules based on the analysis of FTIR spectra and DSC results. The interactions and continuous network improved the mechanical properties of the scaffolds. Meanwhile, increasing the amount of TA also enhanced the hydrophilicity and water absorption capacity of the scaffold, both of which are beneficial for accelerating wound healing. Moreover, a burst release of the TA in the initial stage and a controlled, steady release behavior over time contributed to the highly antibacterial properties of the PCL/TA scaffolds. The fabrication of the composite scaffold supplies a facile, efficient, and controllable approach to address the issue of antibacterial treatment in wound dressing.

Highly Transparent and Mechanically Robust Energy‐harvestable Piezocomposite with Embedded 1D P(VDF‐TrFE) Nanofibers and Single‐walled Carbon Nanotubes

AbstractHerein, highly transparent, flexible, and ultrathin piezocomposite, in which electrospun poly(vinylidene fluoride‐co‐trifluoroethylene) [P(VDF‐TrFE)] nanofibers (NFs) and aerosol‐synthesized single‐walled carbon nanotubes (SWCNTs) are embedded in elastomer matrix, is fabricated. The P(VDF‐TrFE) NF mat is exploited as a piezoelectric layer of the piezocomposite while the SWCNT film is applied as a transparent conductive electrode thereof. The use of these 1D nanomaterials allows the piezocomposite not only to be high transparency along with low diffusion of light (i.e., haze factor) but also to exhibit enhanced mechanical properties. In addition, the coupling effect of piezo‐ and flexoelectricity exhibited from the electrospun NFs and the acid‐doping effect conducted on the SWCNTs facilitates a significant improvement in kinetic energy‐harvesting performance, leading to a maximum output voltage of 26.8 V. Moreover, electrospinning and aerosol chemical vapor deposition methods employed here are facile, scalable, and cost‐effective, thus are expected to accelerate the development of industrially feasible next‐generation wearable electronics.

Preparation of PLGA/ε-polylysine nanofibers and their application for pork preservation

As pork is susceptible to deterioration during production, transportation and marketing, the demand for shelf life extending is urgently desirable. In this work, electrospun poly (lactide–glycolide)/ε-polylysine (PLGA/ε-PL) fiber is developed for pork preservation. ε-PL is well-dispersed in PLGA/ε-PL fiber matrix by hydrogen bonding and its presence can improve the thermal stability. The morphology and size of PLGA/ε-PL fibers are ε-PL content dependent. The PLGA/ε-PL has excellent antibacterial activity towards S. aureus and E. coli, and S. aureus is more susceptible than E. coli. PLGA/ε-PL fiber has good biocompatibility and can prolong the shelf life of pork by 1 day at 25 °C. The PLGA/ε-PL fiber demonstrates great potential in food active packaging and the proposed strategy expand the application fields of ε-PL.

Implantable Electrospun Nanofibers with Wound-Healing Capabilities in the Reduction of Pressure Ulcers

We have fabricated an implantable dressing material able to reduce antipressure ulcer disease. This biomaterial is based on electrospun poly(lactic acid) (PLA) nanofibers (NFs) containing the hydroethanolic extract (HE) of T. ramosissimum. Optimized synthesis conditions (17-PLA/HE NFs) resulted in homogeneous and nonwoven mat structures formed by polymeric NFs. We have included a kinetic release assay where the chemical structures of the main released compounds were identified using nuclear magnetic resonance. The identified compounds include molecules from the family of flavonoids, monoterpenoids, hydroxycinnamic derivatives, and phenolic acids. Interestingly, the terpenoid teuhircoside has been identified in Teucrium ramosissimum for the first time. We have also performed in vivo wound-healing investigations, examining the process of healing of induced pressure ulcers in mice, once applying different dressing materials generated in this work. In these in vivo assays, we were able to demonstrate that the implantable 17-PLA/HE NF material improves wound-healing capabilities, reduces the injury area, and provides a high wound closure percentage from the first days of application. Finally, histological assays showed complete re-epithelialization with 17-PLA/HE NFs. This investigation offers the possibility to fabricate implantable materials containing only the here-determined released compounds.

A flexible electrochemical glucose sensing platform based on an electrospun PVA mat covered with in situ grown silver nanoparticles and a mixed self-assembled monolayer of glucose oxidase and ferrocene.

An electrochemical glucose sensor based on flexible materials is significant for wearable devices used for real-time health monitoring and diagnosis. However, applying flexible electrodes involves complex fabrication processes and might reduce detection sensitivity. To overcome these obstacles, we herein report a novel strategy for preparing a highly flexible enzyme electrode based on an electrospun poly(vinyl alcohol) (PVA) mat decorated with in situ grown silver nanoparticles (nano-Ag) for electrochemical glucose sensing. Ferrocene (Fc) was selected as an electron acceptor for glucose oxidase (GOD) in order to minimize the influence of oxygen. Electron transfer between GOD and Fc was facilitated by confining them within a mixed self-assembled monolayer (SAM) formed on a thin layer of gold deposited on top of the PVA/nano-Ag film. Nano-Ag was found to significantly increase the surface area of the electrode and improve the stability of electrode conductivity during tensile deformation. Electrochemical glucose detection was performed by chronoamperometry in the electroactivity domain of ferrocene, and good linearity (R2 = 0.993) was obtained in the range of 0.2-7 mM with a detection limit of 0.038 mM and a relative standard deviation (RSD) of 1.45% (n = 6). After being stuck to a bendable PDMS slice and bent, respectively, at 30° and 60° 50 times, the electrode showed slight changes in detection results (<4.78%), which remained within 8% when the bending angle increased to 90°. With its high flexibility, good detection performance, and convenient fabrication process, the proposed enzyme electrode showed good potential as a flexible platform for wearable glucose sensing systems.

Preparation and Characterization of Electrospun Poly(lactic acid)/Poly(ethylene glycol)-b-poly(propylene glycol)-b-poly(ethylene glycol)/Silicon Dioxide Nanofibrous Adsorbents for Selective Copper (II) Ions Removal from Wastewater.

The problem of industrial wastewater containing heavy metals is always a big concern, especially Cu2+, which interprets the soil activity in farmland and leaves a negative impact on the environment by damaging the health of animals. Various methods have been proposed as countermeasures against heavy-metal contaminations, and, as a part of this, an electrospun nanofibrous adsorption method for wastewater treatment is presented as an alternative. Poly(lactic acid) (PLA) is a biopolymer with an intrinsic hydrophobic property that has been considered one of the sustainable nanofibrous adsorbents for carrying adsorbate. Due to the hydrophobic nature of PLA, it is difficult to adsorb Cu2+ contained in wastewater. In this study, the hydrophilic PLA/poly(ethylene glycol)-poly(propylene glycol)-poly(ethylene glycol) (PEG-PPG-PEG) nanofibrous adsorbents with different silicon dioxide (SiO2) concentrations were successfully prepared by electrospinning. A hydrophilic group of PEG-PPG-PEG was imparted in PLA by the blending method. The prepared PLA/PEG-PPG-PEG/SiO2 nanofibrous adsorbents were analyzed with their morphological, contact angle analysis, and chemical structure. The Cu2+ adsorption capacities of the different PLA/PEG-PPG-PEG/SiO2 nanofibrous adsorbents were also investigated. The adsorption results indicated that the Cu2+ removal capacity of PLA/PEG-PPG-PEG/SiO2 nanofibrous adsorbents was higher than that of pure ones. Additionally, as an affinity nanofibrous adsorbent, its adsorption capacity was maintained after multiple recycling processes (desorption and re-adsorption). It is expected to be a promising nanofibrous adsorbents that will adsorb Cu2+ for wastewater treatment.

Ibuprofen-loaded electrospun poly(ethylene-co-vinyl alcohol) nanofibers for wound dressing applications.

Chronic wounds are characterized by a prolonged inflammation phase preventing the normal processes of wound healing and natural regeneration of the skin. To tackle this issue, electrospun nanofibers, inherently possessing a high surface-to-volume ratio and high porosity, are promising candidates for the design of anti-inflammatory drug delivery systems. In this study, we evaluated the ability of poly(ethylene-co-vinyl alcohol) nanofibers of various chemical compositions to release ibuprofen for the potential treatment of chronic wounds. First, the electrospinning of poly(ethylene-co-vinyl alcohol) copolymers with different ethylene contents (32, 38 and 44 mol%) was optimized in DMSO. The morphology and surface properties of the membranes were investigated via state-of-the-art techniques and the influence of the ethylene content on the mechanical and thermal properties of each membrane was evaluated. Furthermore, the release kinetics of ibuprofen from the nanofibers in a physiological temperature range revealed that more ibuprofen was released at 37.5 °C than at 25 °C regardless of the ethylene content. Additionally, at 25 °C less drug was released when the ethylene content of the membranes increased. Finally, the scaffolds showed no cytotoxicity to normal human fibroblasts collectively paving the way for the design of electrospun based patches for the treatment of chronic wounds.

Cell Behavior Changes and Enzymatic Biodegradation of Hybrid Electrospun Poly(3-hydroxybutyrate)-Based Scaffolds with an Enhanced Piezoresponse after the Addition of Reduced Graphene Oxide.

This is the first comprehensive study of the impact of biodegradation on the structure, surface potential, mechanical and piezoelectric properties of poly(3-hydroxybutyrate) (PHB) scaffolds supplemented with reduced graphene oxide (rGO) as well as cell behavior under static and dynamic mechanical conditions. There is no effect of the rGO addition up to 1.0 wt% on the rate of enzymatic biodegradation of PHB scaffolds for 30 d. The biodegradation of scaffolds leads to the depolymerization of the amorphous phase, resulting in an increase in the degree of crystallinity. Because of more regular dipole order in the crystalline phase, surface potential of all fibers increases after the biodegradation, with a maximum (361 ± 5mV) after the addition of 1 wt% rGO into PHB as compared to pristine PHB fibers. By contrast, PHB-0.7rGO fibers manifest the strongest effective vertical (0.59 ± 0.03 pm V-1 ) and lateral (1.06 ± 0.02 pm V-1 ) piezoresponse owing to a greater presence of electroactive β-phase. In vitro assays involving primary human fibroblasts reveal equal biocompatibility and faster cell proliferation on PHB-0.7rGO scaffolds compared to pure PHB and nonpiezoelectric polycaprolactone scaffolds. Thus, the developed biodegradable PHB-rGO scaffolds with enhanced piezoresponse are promising for tissue-engineering applications.

Preparation of fluffy bimodal conjugated electrospun poly(lactic acid) air filters with low pressure drop.

Electrospun nanofiber membranes have been extensively studied as air filters. However, their limited filtration efficiency for submicron inhalable particulate matter (PM), high resistance to filtration, and limited capacity to hold dust have hindered their widespread use. The majority of materials come from petroleum, and the use of organic solvents during the spinning process has a significant negative impact on the environment. In this work, a sustainable method has been proposed for producing filters using poly(lactic acid) (PLA) with a bimodal diameter distribution through conjugated electrospinning. This technique allows for the continuous production of interconnected micro/nano hybrid porous membranes, resulting in reduced resistance and improved dust holding capacity. The filtration efficiency, pressure drop, long-term filtration performance, and actual performance of the conjugated bimodal membrane (CBM) were extensively investigated. The results indicate that the filter has a high capacity for retaining particles, with filtration efficiencies of 99.94% for PM 0.3 and 99.96% for PM 2.5. It also demonstrates a high quality factor (0.078 Pa-1 for PM 0.3 and 0.084 Pa-1 for PM 2.5), long-term stability (a decrease of 2.35% for PM 0.3 and 0.05% for PM 2.5 over a period of 60 days) and outstanding dust holding capacity (9.17 g m-2). The conjugated bimodal membrane (CBM) shows a 22.64% decrease in resistance compared to the non-conjugated bimodal membrane (BM). In general, the approach outlined in this work provides valuable insights into the development of high-performance biodegradable air filters. These filters have improved filtration efficiency and reduced resistance.

Electrospun poly(3-hydroxybutyrate-co-3-hydroxyvalerate) scaffolds – a step towards ligament repair applications

ABSTRACT The incidence of anterior cruciate ligament (ACL) ruptures is approximately 50 per 100,000 people. ACL rupture repair methods that offer better biomechanics have the potential to reduce long term osteoarthritis. To improve ACL regeneration biomechanically similar, biocompatible and biodegradable tissue scaffolds are required. Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), with high 3-hydroxyvalerate (3HV) content, based scaffold materials have been developed, with the advantages of traditional tissue engineering scaffolds combined with attractive mechanical properties, e.g., elasticity and biodegradability. PHBV with 3HV fractions of 0 to 100 mol% were produced in a controlled manner allowing specific compositions to be targeted, giving control over material properties. In conjunction electrospinning conditions were altered, to manipulate the degree of fibre alignment, with increasing collector rotating speed used to obtain random and aligned PHBV fibres. The PHBV based materials produced were characterised, with mechanical properties, thermal properties and surface morphology being studied. An electrospun PHBV fibre mat with 50 mol% 3HV content shows a significant increase in elasticity compared to those with lower 3HV content and could be fabricated into aligned fibres. Biocompatibility testing with L929 fibroblasts demonstrates good cell viability, with the aligned fibre network promoting fibroblast alignment in the axial fibre direction, desirable for ACL repair applications. Dynamic load testing shows that the 50 mol% 3HV PHBV material produced can withstand cyclic loading with reasonable resilience. Electrospun PHBV can be produced with low batch variability and tailored, application specific properties, giving these biomaterials promise in tissue scaffold applications where aligned fibre networks are desired, such as ACL regeneration.

Superhydrophilic microfibrous adsorbent with broad-spectrum binding affinity to effectively remove diverse pollutants from aqueous solutions

The diversity of pollutants in wastewater, such as heavy metal ions, dyes, and antibiotics, has threatened the ecological environment and human health for decades. To tackle this harsh issue, we developed a superhydrophilic microfibrous adsorbent to remove diverse pollutants by functionalizing electrospun poly(glycidyl methacrylate) fibers with a high density of iminodiacetic acid (IDA) functional groups. Thanks to strong and broad-spectrum binding affinity of the IDA group and good surface wettability, the resulting superhydrophilic microfibrous adsorbent exhibits excellent adsorption performance toward cationic organic dyes, heavy metal ions, and antibiotics via electrostatic interaction or coordination. It can achieve extraordinarily high adsorption capacities of 2569.70 mg/g, 1621.49 mg/g, 2420.18 mg/g, 175.44 mg/g, 123.46 mg/g, and 389.53 mg/g towards methylene blue, malachite green, methyl violet, Cu2+, Cr3+, and tetracycline, respectively. The absorbent can realize more than 98 % removal rate of these pollutants from water within 20 min. Moreover, its porous membrane structure and pH-dependent adsorption selectivity provide the developed adsorbent with outstanding recyclability. The spent adsorbent can be easily regenerated via a dilute acid solution and reused at least 10 times without apparent loss in performance.

Surface collagen functionalization of electrospun poly(vinyl alcohol) scaffold for tissue engineering

The limited solubility of collagen is one of the main limitations to achieving electrospun mats based on this biomacromolecule. Postelectrospinning functionalization has emerged as a suitable alternative for effective collagen incorporation into biocompatible nanofiber mats without compromising their bioactivity. In this work, the enrichment of poly (vinyl alcohol) (PVA) nanofibers was attained by their postelectrospinning surface functionalization with nonsolubilized collagen through the esterification of hydroxyl groups of the PVA backbone via Steglich esterification using mild conditions. FTIR and XPS confirmed successful ester bond formation, while the thermal and mechanical results show the different behavior of PVA nanofibers after functionalization. Collagen functionalization enhanced the cytocompatibility behavior of PVA nanofibers, promoting the growth of HEK-293 cells. Thus, this novel methodology allows for the bioconjugation of nonsolubilized collagen to the surface of PVA nanofibrous mats, producing cytocompatible scaffolds while preserving the structural capabilities of collagen to support cell attachment and proliferation.

Fabricating a robust POSS-PCL nanofiber scaffold for nesting of mesenchymal stem cells: potential application in bone tissue regeneration

BackgroundAccording to recent studies, electrospun Poly (Ɛ-caprolactone) (PCL) is an absorbing candidate for the formulation of biocompatible scaffolds used in tissue engineering. Tissue engineering is a set of techniques for producing or reconstructing tissue, whose primary purpose is to restore or improve the function of tissues in the human body. Tissue engineering combines the principles of materials and cell transplantation to develop alternative tissues or promote endogenous regeneration. However, this electrospun scaffold, consisting of PCL, has disadvantages such as low cell adhesion, inactivity of the surface, osteoinduction, and acidic destruction of the scaffold that causes inflammation at the implant site, often making it unsuitable implant. This study aimed to improve PCL base cellular scaffolds with the formulation of polyhedral oligomeric silsesquioxane – Polycaprolactone (POSS-PCL) nanofiber scaffolds. The present research focuses on the synthesis of nanofibers for their cell interaction features, and application in bone tissue engineering and regeneration.ResultsPOSS/ PCL Nanocomposites with 2, 5, and 10 wt.% of POSS were synthesized in the Trichloromethane, then POSS – PCL Nanofibers were prepared by the electrospinning technique. In this study, the structures of nanohybrids and nanofibers have been evaluated by FTIR, HNMR, XRD, SEM, EDX, and DSC. The biocompatibility of formulated POSS-PCL scaffolds was detected using mesenchymal stem cells (MSCs). Then several parameters were examined, involving DCFH ROS detection system, gene expression (cell viability/apoptosis, osteogenesis potentiality, and redox molecular homeostasis.ConclusionsBased on our results, POSS-PCL nano-scaffolds in comparison with PCL have shown a robust potentiality in homing, growth, and differentiation of stem cells.Graphical Synthesis of POSS-PCL Nanofibers and their potential application in Bone Regeneration.

Fabrication and assessment of bifunctional electrospun poly(l-lactic acid) scaffolds with bioglass and zinc oxide nanoparticles for bone tissue engineering

Electrospun scaffolds based on poly(l-lactic acid) (PLLA) with bioglass (n-BG) and zinc oxide (n-ZnO), and mixture of both, were developed to design bifunctional biomaterials with enhanced bioactive and biocidal properties. The presence of n-BG increased the fiber diameter of the pure PLA from 1.5 ± 0.3 μm to 3.0 ± 0.8 μm for 20 wt%. ZnO and the mixed nanoparticles did not significantly affect the morphology. The mechanical properties decreased with the presence of nanoparticles. Scaffolds based on PLA/n-BG promoted hydroxyapatite (HA) formation in simulated body fluid (SBF) that was inhibited with the presence of ZnO. Notably, mixed particles produced bioactivity although at longer times. The incorporation of n-ZnO produced a biocidal capacity against S. aureus in the polymeric scaffold, reaching a viability reduction of 60 % after 6 h of exposure. When both types of nanoparticles were combined, the bacterial viability reduction was 30 %. Pure PLA scaffolds and the composites with n-BG showed good ST-2 bone marrow-derived cell line viability, scaffolds with n-BG (pure or mixture) presented lower viability. Results validated the use of both n-BG and n-ZnO fillers for the development of novel bifunctional PLA-based scaffolds with both bioactive and biocidal properties for bone tissue engineering applications.

A 3D, Compartmental Tumor-Stromal Microenvironment Model of Patient-Derived Bone Metastasis

Bone is a frequent site of tumor metastasis. The bone-tumor microenvironment is heterogeneous and complex in nature. Such complexity is compounded by relations between metastatic and bone cells influencing their sensitivity/resistance to chemotherapeutics. Standard chemotherapeutics may not show efficacy for every patient, and new therapeutics are slow to emerge, owing to the limitations of existing 2D/3D models. We previously developed a 3D interface model for personalized therapeutic screening, consisting of an electrospun poly lactic acid mesh activated with plasma species and seeded with stromal cells. Tumor cells embedded in an alginate-gelatin hydrogel are overlaid to create a physiologic 3D interface. Here, we applied our 3D model as a migration assay tool to verify the migratory behavior of different patient-derived bone metastasized cells. We assessed the impact of two different chemotherapeutics, Doxorubicin and Cisplatin, on migration of patient cells and their immortalized cell line counterparts. We observed different migratory behaviors and cellular metabolic activities blocked with both Doxorubicin and Cisplatin treatment; however, higher efficiency or lower IC50 was observed with Doxorubicin. Gene expression analysis of MDA-MB231 that migrated through our 3D hybrid model verified epithelial-mesenchymal transition through increased expression of mesenchymal markers involved in the metastasis process. Our findings indicate that we can model tumor migration in vivo, in line with different cell characteristics and it may be a suitable drug screening tool for personalized medicine approaches in metastatic cancer treatment.
