Figure 4. ALP activity and Osteocalcin protein quantification.
(A) ALP activity was significantly higher in the PRC treated cells compared to other groups at day 8 and 16; (B) Osteocalcin level gradually increased, peaking at day 24, with PRC group having the highest concentration throughout the study duration. The ALP activity and osteocalcin levels in each sample were normalized to the amount of DNA in the sample. Data are represented as the means ± SD. * denotes statistical significance between the indicated pairs (p < 0.05). (OM denotes osteogenic medium group).
