BACKGROUND:The bone marrow mesenchymal stem cel s can be widely used, the three-lineage differentiation capacity and immune induction characteristics make it widely used in regenerative medicine. OBJECTIVE:To investigate the new method to isolate the Flk-1+mesenchymal stem cel s from mouse bone marrow, and to detect the biological characteristics of Flk-1+mesenchymal stem cel s. METHODS:The mononuclear cel s were isolated from the bone marrow and the original mesenchymal stem cel s were in vitro cultured and amplified. The cel cycle, phenotype and multilineage differentiation capacity were detected. RESULTS AND CONCLUSION:The original mesenchymal stem cel s derived from mice bone marrow were fibrolbast like, and most of them stayed in G0/G1 phase. Cel phenotype test showed they could highly express Flk1, CD13, CD29, CD44;the bone marrow-derived Flk-1+mesenchymal stem cel s under light microscope showed a fibroblast-like or polygonal adherent growth, and under certain circumstances, they exhibited osteogenic, adipogenic and chondrogenic differentiation. Bone marrow-derived Flk-1+mesenchymal stem cel s have multilineage differentiation potential.
