After 2 days of administration of granulocyte colony-stimulating factor, mouse blood contains high levels of serially reconstituting hematopoietic stem cells.
In mice, mobilization of serially reconstituting hematopoietic stem cells precedes that of clonogenic progenitors.
In half of healthy volunteers tested, after 2 days of administration of granulocyte colony-stimulating factor, mobilized CD34+ cells are enriched in CD34+CD38− primitive progenitors.
