Alkaline phosphatase activity of 10 and 20 wt% cell-laden hydrogels with and without gelatin microparticles (GMPs) after culture in complete osteogenic medium after 0, 7, 14, 21, and 28 days. (*) indicates significant difference across timepoints in the same group (p<0.05). Letters A–C indicate differences across groups at the same timepoint. Bars with different letters indicate significant difference (p<0.05). Unmarked bars show no significant difference. Error bars indicate standard deviation (n=3–4).
