Abstract:
AIM: To characterize the gene expression of sortilin on adipogenic and osteogenic differentiation in mesenchymal stem cells (MSCs) in vitro and explore its significance.METHODS: MSCs derived from human bone marrow were isolated and cultured in vitro ,then were stimulated in osteogenic medium and adipogenic medium,respectively. Osteopontin and lipoprotein lipase were detected by RT-PCR. Sortilin expression was analyzed by semiquantitative RT-PCR. RESULTS: 1.MSCs displayed the potential of differentiation into osteoblast and adipocyte. 2.Sortilin was upregulated one day after osteogenic induction and remained upregulated for a week. The expression of sortilin was significant increased on day 3( P 0.05).CONCLUSION: Sortilin may be useful to modulate the osteogenic differentiation and may not be necessary for adipocyte commitment in MSCs. The regulation of sortilin expression may provide new protocal and strategy for the treatment of osteoporosis and osteopenic disease.
