Fig. 6. Alamar blue dye reduction% of different sample groups (A), total DNA quantification using pico green assay of different sample groups (B), ALP activity (IU L−1) of different sample groups cultured with UMSCs for 21 days (C). * indicated a significant difference between sample groups at same time point with P < 0.05 and # indicates a significant difference between different time points within the same group with P < 0.05.
