Abstract
Mesenchymal stem cells (MSCs) are multipotent cells and are considered a potential source for tissue and organ repair due to their self-renewal, proliferation, and differentiation abilities. However, in most cases, MSCs are needed to be stimulated with external growth factors to promote their proliferation and differentiation. Over the past decade, it has been demonstrated that nanomaterials could facilitate MSC proliferation and differentiation, and excellent efforts are carried out to investigate their possible modulating pattern and mechanisms for MSC differentiation. Europium hydroxide (EuIII(OH)3) nanorods (EHN) are well-researched for their biomimicking properties and act as a substitute for growth factors that induce cell proliferation, migration, and differentiation. In the current study, the human MSCs were chosen as an in vitro model for evaluating the role of EHN in modulating the differentiation process of MSCs into neuronal and glial lineages. The characterization of MSCs and differentiated neuronal cells observed by flow cytometry, confocal, and gene marker expression studies supported our hypothesis that the EHNs are pro-angiogenic and pro-neurogenic. Finally, altogether our results suggest that EHNs have the potential to play an essential part in developing novel treatment strategies for neurodegenerative diseases and spinal cord injuries based on the nanomedicine approach.
