[Clonal nature of fibroblast colonies formed by stromal bone marrow cells in culture].
The clonal nature of CFUf-derived fibroblast colonies was tested in mixed cultures of CBA and CBAT6T6 bone marrow cells. Inoculation of marrow cell suspensions into flasks coated with poly-I-lysin has proved that no stromal aggregates were present among cells subjected to explantation. Marrow cell cultures depleted of macrophages and myeloid cells were used for chromosome analysis. The coincidence of karyotypes within a stromal colony was found in mixed cultures, which proves that CFUf-derived fibroblast colonies are cell clones.
