Effects of transfection of bone morphogenetic protein-2 and insulin-like growth factor-1 gene on the proliferation of bone marrow mesenchymal stem cells with high glucose condition
Chinese journal of experimental surgery(2011)
Abstract
Objective To observe the proliferation of bone marrow stromal cell (BMSC) transfected by bone morphogenetic protein-2 (BMP-2) and insulin-like growth factor-1 ( IGF-1 ) gene under high glucose condition.Methods Ad-BMP-2 and Ad-IGF-1 transfected rat BMSC,protein expression of BMSC were detected by Western blotting analysis.Methyl thiazol tetrazolium (MTT) assay and flow cytometry to observe the proliferation potential of BMSC.Results In the Western blotting analysis,positive signal lane of protein was observed in transfected group.MTT assay show that proliferation reached the peak in all groups on the fifth day,and the absorbency values of A to E group were 0.324 ± 0.027,0.319 ± 0.017,0.622 ±0.028,0.626 ± 0.020,0.778 ± 0.031.Flow cytometry show that the proliferative percentage from A to E group were 23.92 ±3.07,23.51 ±2.11,34.37 ±6.85,35.04 ± 1.45,42.56 ± 1.15.Conclusion BMP-2 or IGF-1 can promote the proliferation of BMSC under high glucose condition,but the combined has the synergy effect.\r\n\r\nKey words: \r\nBMP-2; IGF-1; BMSC; High glucose; Cell proliferation
