doi: 10.2147/dddt.s367277
Figure Lengend Snippet: Figure 5 CORM-3-stimulated osteogenic differentiation of rat BMSCs was modified by up- or down-regulation of Wnt3a. (A) The rat BMSCs were transfected with pcDNA3.1-Wnt3a and Wnt3a siRNA. 24 hours after transfection, the cell viabilities were measured. After 48 hours, the protein expressions of Wnt3a were determined by Western blot and image analysis. (B and C) The rat BMSCs were transfected with pcDNA3.1-Wnt3a or NC (B), Wnt3a siRNA or NC (C) for 24 hours and then cultured in the osteogenic medium containing 200 μΜ CORM-3. Meanwhile, cells in the CORM-3 or control group were cultured in the osteogenic medium containing 200 μΜ CORM- 3 or control medium respectively. After 3 and 7 days, the mRNA expressions of Runx2 and OPN were determined by RT-qPCR, normalized to β-actin. (D and E) The rat BMSCs were cultured as B and C described above. After 3 and 7 days, the protein expressions of Runx2 and OPN were determined by Western blot, then analysed using ImageJ software, normalized to GAPDH. (F) The rat BMSCs were cultured in different mediums as described above. After 14 days, the mineralization was determined by alizarin red staining and semi quantitative analysis. The experiment was repeated for three times. Data were presented as the mean±standard deviation (n=3). ^ P<0.05 vs control; * P<0.05 as indicated.
Article Snippet: After blocking with 5% non-fat milk, membranes were incubated overnight at 4°C with primary antibodies: rabbit anti-rat Runx2 monoclonal antibody (cat no., 12556s, 1:1000 dilution; Cell Signaling Technology, Inc., Danvers, MA, USA), rabbit anti-rat OPN polyclonal antibody (cat no., ab8448, 1:1000 dilution; Abcam, Cambridge, Britain), and rabbit anti-rat Wnt3a polyclonal antibody (cat no., WL0199a, 1:400 dilution; Wanleibio, Shenyang, China), respectively.
