Effect of Foreign Fetal and Newborn Blood-Forming Tissues on Survival of Lethally Irradiated Mice

Abstract
Lethally irradiated mice that received blood-forming cells from homologous fetal liver showed better long-term survival and lymphatic tissue recovery than those treated with blood-forming cells from adult homologous bone marrow. In both cases there was transplan-tation and persistence of erythropoietic cells.
