Figure Lengend Snippet: hASC survival and differentiation in GelMA hydrogels. ( A ) CCK8 assay of hASCs encapsulated in the GelMA hydrogel at different time points (1 week intervals). Results are reported as mean ± SEM of n = 3 samples/group. ( B ) Representative confocal imaging of Dead/live fluorescence staining of hASCs in the GelMA hydrogel after 3 weeks of culture. Red cells are dead while green cells are alive. ( C ) Alcian blue staining of GelMA hydrogel after 24 h and 3 weeks of culture. ( D ) Alizarin red staining of GelMA hydrogel after 24 h and 3 weeks of culture. ( E , F ) Confocal imaging of immunofluorescence for COL2A1 (green) and OCN (red) in hASCs encapsulated in GelMA hydrogel after 3 weeks of culture.

Article Snippet: Briefly, samples were incubated with rabbit polyclonal anti-collagen type II alpha 1 (COL2A1) antibody (Merck) and rabbit polyclonal anti-osteocalcin (OCN) antibody (Thermo Fisher Scientific) for 1 h at room temperature.
