| Abstract: | Objective To isolate rabbit bone marrow mesenchymal stem cells (MSCs), and observe the inducing effect of growth factors on MSCs to express chondrocytic phenotype. Methods MSCs were seperated from bone marrow of New Zealand rabbit. TGF-β1, IGF-I, Vitamin C and dexamethasone were added into culture medium to induce proliferation and differention of MSCs. Procollagen α1(Ⅱ) mRNA in cells was detected by RT-PCR to observe the chondrogenous effect of inducing factors. ALP in culture medium was detected by automatic biochemical analyser, and lipid droplet in cells was stained by Sudan Ⅲ to clarify whether these factors given had osteogenic and adipogenic potential. Results Expression of articular cartilage specific procollagen α1 (Ⅱ)mRNA was promoted by inducing factors-TGF-β1, IGF-I, Vitamine C and dexamethasone; elevated level of ALP in culture medium and lipid droplet in cells were also detected. Whereas ALP level was decreased and lipid stain were negative in groups without dexamethasone. Conclusion ① Expression of chondrocytic phenotype by MSCs could be induced by the synergistic action of TGF-β1, IGF-I and Vitamine C. ② Dexmathasone had osteogenic and adipogenic potential, it should not be chosen to induce chondrogenic differention of MSCs. |
