Figure Lengend Snippet: Osteogenic differentiation of rabbit MSCs cultured on electrospun PBSGL n membranes at days 4, 7, 14, and 21 in the osteogenic media: DNA ( a ); ALP activity ( b ); calcium content ( c ); gene expression (Col-α1 ( d ), Runx-2 ( e ), and OCN ( f )); protein expressions of OCN and Col-α1 at day 21 relative to β actin expression ( g ); Western blotting bands for OCN (12 kDa), Col-α1 (130 kDa), and β actin (42 kDa) (h). Three different gels (with the same acquisition settings and exposure parameters) were used to visualize the relative protein expressions of OCN, Col-α1 and β actin proteins. Alizarin Red staining showing deposited calcium ions on the electrospun PBSGL0 (i-1), PBSGL10, (i-2) PBSGL20, (i-3) and PBSGL40 (i-4) nanofibers at day 21. An asterisk denotes a statistically significant difference P < 0.05) between the test and control group at each time point. A “#” sign indicates a statistically significant difference between the test and all other groups at each time point. Sample size selected was 5.
