Figure 9.
Osteogenic differentiation of DPSCs cultured on CCNFs and PACNs membranes at days 7, 14, and 21 in the osteogenic medium: activity of ALP (a); sexpression of genes [Runx-2 (b), and OCN (c)]; expression of proteins OCN and Runx-2 at day 21 compared to the expression of GAPDH (d); bands of western blotting for OCN (6 kDa), Runx-2 (55 kDa), and GAPDH (37 kDa) (f). We used three different gels to visualize the expression of OCN, Runx-2, and GAPDH proteins relative to each other (while keeping similar exposure parameters and acquisition settings). An asterisk shows a significant difference (p < 0.05) between the control and test groups.
