[Proliferative and differentiation potentials of skeletogenic bone marrow colony-forming cells].
The clonal nature of bone marrow fibroblast colonies derived from clonogenic bone marrow osteogenic cells (CFUf) was proved by the chromosome analysis. During subsequent passages of multi-colony derived bone marrow fibroblast strains there occurs a pronounced increase in the cell number and in the number of osteogenic units (tested by transplantation in diffusion chambers). Single colony-derived strains are capable of forming bone and cartilage simultaneously. It follows that CFUf or part of them are clonogenic cells with high proliferative potentials and are common precursors for bone and cartilage tissue. Thus, CFUf may be regarded as osteogenic stem cells.
