title: Effect of pyran copolymer on murine hemopoiesis.
abstract: Pyran Copolymer (NSC-46015), a divinyl-ether maleic anhydride leads to a significant shift in distribution of nucleated cells and CFUs in the bone marrow and spleen. The bone marrow cellularity and the CFUs content reach a nadir 4 to 6 days after Pyran injection, simultaneous rise in spleen cellularity and CFUs concentration of circulating pluripotent stem cells by a factor of 10 to 45 and a concomitant rise of CFUc is seen. the origin of the mobilized pluripotent stem cells is likely to be the bone marrow, not athe spleen.
