Photo-crosslinkable, bone marrow-derived mesenchymal stem cells-encapsulating hydrogel based on collagen for osteogenic differentiation

Many patients suffer from bone injury and self-regeneration is not effective. Developing new strategies for effective bone injury repair is highly desired. Herein, collagen, an important component of the extracellular matrix, was modified with glycidyl methacrylate. The water solubility and photochemical cross-linking ability of the resulting collagen derivative was then improved. Thereafter, BMSC-laden hydrogel was fabricated using collagen...
