Transplantable hematopoietic cells with multilineage reconstituting ability can be quantitated in suspensions of human or murine cells using similar assay procedures. The incorporation into these assays of stringently defined functional endpoints ensures a high degree of specificity for the cells detected. Application of these assays to stem cell-containing suspensions after they have been stimulated for several days with defined cytokines in vitro, or by a mixture of defined and/or undefined factors in vivo, has shown that net amplifications in these populations can be obtained under both circumstances. Such studies have allowed cytokine conditions that support stem cell self-renewal divisions to be identified and have also provided evidence that stem cell regeneration can be manipulated both in vitro and in vivo by altering the molecular milieu of the responding cells. These observations pave the way to future delineation of mechanisms that control the normal behavior, pathology and future clinical exploitation of hematopoietic stem cell populations.
