摘要:
Stromal cell lines were established from bone marrow of temperature-sensitive T-antigen gene transgenic mice. These stromal cell lines consisted of fibroblasts, endothelial cells, and preadipocytes. We found that these stromal cell lines exhibited phenotypic changes depending on the inactivation of T-antigen and growth condition; one preadipocyte line was induced toward adipocytes and osteogenic cells, and several preadipocyte and endothelial cell lines were induced toward muscle cells and adipocytes. Some cell lines showed bipotential characters. These results indicated that stromal cells consisting of bone marrow hematopoietic microenvironment are derived from multipotent mesenchymal stem cells.
