Figure 5.
(a) Alizarin red stained hMSC-laden alg/col 1/0.5 hydrogels with 0.5, 1 and 5 million cells/mL densities and incubated in basal medium (BM) or osteogenic medium (OM) for 28 days (b) ALP activity of hMSCs encapsulated in alg/col 1/0.5 hydrogels with 0.5, 1, or 5 million cells/mL density and incubated in BM or OM for 28 days (c) calcium content of hMSCs-laden alg/col 1/0.5 hydrogels with 0.5, 1, or 5 million cells/mL density and incubated in BM or OM for 28 days. “An asterisk” represents a statistically significant difference between the test group and all other groups at that time point. Error bars correspond to means ±1 SD for n = 3.
