Mobilization of canine hemopoietic stem cells by pyran copolymer (NSC 46015). 1984

A R Zander, and J Templeton, and K N Gray, and G Spitzer, and D S Verma, and K A Dicke

Pyran copolymer (NSC 46015), a divinyl ether maleic anhydride of broad spectrum molecular weight, was infused into six normal mongrel dogs. The effect on canine blood and bone marrow colony forming units in culture (CFU-C) was followed over an 11-day period. Significant elevation of circulating CFU-c was noted 2 days after pyran infusion; normalization occurred by day 7 postinfusion. Bone marrow CFU-C were decreased 2 days and 5 days after pyran administration. A further increase in circulating CFU-C was noted when pyran was administered twice, 5 days apart. The mobilizing effect of pyran copolymer appears promising enough to warrant further exploration of blood as a source of hemopoietic stem cells for transplantation purposes.
