Demonstration of hemopoietic stem cells in the peripheral blood of baboons
by cross circulation
R Storb, TC Graham, RB Epstein, GE Sale and ED Thomas
Baboons were given 1200 R total body irradiation from two opposing 60Co
sources. Three animals were given supportive therapy only and died, as
expected, within 8 days of irradiation with profound marrow hypoplasia.
Five baboons were cross-circulated with unirradiated partners and died
within 14 days with evidence suggestive of graft-versus-host disease. Their
marrows were repopulated with hemopoietic precursor cells, and three of the
five had rises in peripheral white blood cell counts to more than 1500/cu
mm before death. These results are compatible with the presence of
hemopoietic stem cells in the peripheral blood of a nonhuman primate, the
baboon.
