Fig. 1From: Inhibition of valve mesenchymal stromal cell calcium deposition by bFGF through alternative polyadenylation regulation of the CAT geneAlizarin Red S staining and western blotting for OPN of PVICs induced by OIM. A, Alizarin Red S staining of PVICs induced by osteogenic medium OM for 7 days, control (normal culture medium), OIM (osteogenic medium). B, Quantitative analysis of calcium nodules before and after OIM treatment. C, The protein expression of OPN and RUNX2 were increased induced by OIM for 72 hrs. Actin was used as the control.
