title: Hemopoietic precursor cells in human peripheral blood.
abstract: Human peripheral blood contains two types of stem cells that differentiate along the granulocytic pathway. They are separable by their ability to form colonies in agar in vitro (CFU-C) and in plasma clots in diffusion chambers in vivo (CFU-DG). Kinetic studies suggest that CFU-DG represents an intermediate between the still hypothetical human pluripotent stem cell and CFU-C.
