Stroma-dependent long-term bone marrow cultures (LTBMC) assay the ability of primitive haematopoietic stem cells (HSC) for long-term production of clonable progenitors. We have developed a limiting dilution type LTBMC assay allowing frequency analysis of transiently repopulating HSC and long-term culture initiating cells (LTC-IC) without the necessity to(More)
It has been reported that stroma-dependent cultures support proliferation of hematopoietic stem cells (HSC). In order to investigate the effect of soluble stromal factors, we developed short-term serum-low liquid cultures in which the effect of stroma-conditioned media (SCM) from the murine FBMD-1, and human L87/4 and L88/5 cell lines was studied on the(More)
Stroma-supported long-term cultures (LTC) allow estimation of stem cell quality by simultaneous enumeration of hematopoietic stem cell (HSC) frequencies in a graft using the cobblestone area forming cell (CAFC) assay, and the ability of the graft to generate progenitors in flask LTC (LTC-CFC). We have recently observed that the number and quality of(More)
