Calcium deposition in photocrosslinked poly(Pro-Hyp-Gly) hydrogels encapsulated rat bone marrow stromal cells.

Reproducing the features of the extracellular matrix is important for fabricating three-dimensional (3D) scaffolds for tissue regeneration. A collagen-like polypeptide, poly(Pro-Hyp-Gly), is a promising material for 3D scaffolds because of its excellent physical properties, biocompatibility, and biodegradability. In this paper, we present a novel photocrosslinked poly(Pro-Hyp-Gly) hydrogel as a 3D scaffold for simultaneous rat bone marrow stromal cell (rBMSC) encapsulation.
