[Renewal of hematopoietic stem cell clones in long-term bone marrow cultures].

Abstract

In long-term cultures of murine bone marrow, clonal succession of hemopoietic cells was observed as measured by karyologic analysis. There were high oscillations in self-renewal of CFUs in the cultures. A close correlation between the CFUmix karyotype and mitotic non-adherent cells in culture (but not between these cell types and CFUs) was revealed.
