Ucma/GRP^−/− mVSMCs show increased expression of osteo/chondrogenic markers. Cells were treated with control (CM) or osteogenic medium (OM, with 2.6 mM phosphate) for 12 days. Panels (A–D) qPCR analysis of osteo/chondrogenic gene expression, n = 4–7. Statistical significance was assessed using t-test (Osteocalcin) or ANOVA (E) Western blotting analysis of osteo/chondrogenic markers. Both WT and KO cells were treated with OM. Figure shows full western blots obtained by cutting of a full-sized membrane prior to antibody incubations. Numbers in the middle show molecular weights of the protein standard. Numbers on the right show the expected molecular weights of the proteins. Panels F–I quantification of western blotting results from panel E, n = 3. Statistical significance was assessed using t-test. All graphs show mean + SD. *p between 0.05–0.01, **p between 0.001–0.01.
