a) Scheme for osteogenic predifferentiation of MSCs in vitro. MSCs were cultured in complete osteogenic medium containing 10−8 M dexamethansone following 3 days of expansion. Cells were encapsulated within hydrogels after 6 days of in vitro culture. b) Chemical structure of the thermogelling macromers (TGM) and polyamidoamine (PAMAM) crosslinker comprising the injectable hydrogel system for encapsulation of gelatin microparticles (purple spheres) with undifferentiated or predifferentiated MSCs.
