Hemopoietic precursor cells in human peripheral blood.
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.
