Abstract
Bone regeneration is a critical and intricate process vital for healing fractures, defects, and injuries. Although conventional bone grafts are commonly used, they may fall short of optimal outcomes, thereby driving the need for alternative therapies. This research endeavors to explore synergistically designed Hyalo Glass Gel (HGG), and its explicitly for bone tissue engineering and regenerative medicine. The HGG composite comprises a modifiable calcium-based bioactive phosphosilicates-incorporated/crosslinked gelatin-hyaluronic scaffold showcasing promising functional characteristics. The study underscores the distinct attributes of each constituent (gelatin (Gel), hyaluronic acid (HA), and 45S5 calcium sodium phosphosilicates (BG)), and their cooperative influences on the scaffold's performance. Careful manipulation of crosslinking methods facilitates customization of HGG's mechanical attributes, degradation kinetics, and structural features, aligning them with the requisites of bone tissue engineering applications. Moreover, the integration of BG augments the scaffold's bioactivity, thereby expediting tissue regenerative processes. This comprehensive evaluation encompasses HGG's physicochemical aspects, mechanical traits rooted in viscoelasticity, as well as its biodegradability, in-vitro bioactivity, and interactions with stem cells. The result obtained underscores the viscoelastic nature of HGG, substantiating its capacity to foster mesenchymal stem cell viability, proliferation, and differentiation. Significantly, HGG manifests biocompatibility and adjustable attributes, exhibits pronounced drug (vancomycin) retention abilities, rendering it apt for wound healing, drug delivery, and bone regeneration. Its distinctive composition, tailored attributes, and mimicry of bone tissue's extracellular matrix (ECM) due to its bioactive nature, collectively situate its potential as a versatile biomaterial for subsequent research and development endeavors with compelling prospects in bone tissue engineering and regenerative medicine.
