Hemopoietic stem cells "age" structure revealed by the exogenous colony forming method.
The number of colony forming units in mice following the transplantation of cells of bone marrow, spleen and embryonal liver, forming exogenous spleen colonies on 5, 8 and 11 days has been determined. It has been shown that stem cell subpopulation forming colonies on 5 day (CFUs-5) was notable for lower capacity for self maintenance, and contained predominantly by erythroid colonies, these CFUs-5 were mainly in embryonal liver and less in reduced in the hemopoietic populations in mice.
