Abstract:
Human bone marrow mesenchymal stem cells are thought to be multipotent cells, which are present in adult marrow, that can replicate as undifferentiated cells and that have the potential to differentiate to lineages of mesenchymal tissues, including bone, cartilage, fat, tenden, muscle, and marrow stroma. Cells that have the characteristics of human mesenchymal stem cells could be isolated from marrow aspirates of human and animals. This study was designed to identify and characterize genes specifically expressed by osteogenic supplements-treated cells by suppression subtractive hybridization(SSH) method. The results were as follows: 1. 2 genes were upregulated genes in osteogenic diffeentiation of hMSCs, which is further proved by Northern blot analysis. 2. IGFBP-2 has been identified playing an important role in bone formation. 3. HF1 was also upregulated during osteogenic differentiation, but its role in bone formation is not clear yet.
