Abstract
Baboons exposed to acute hemolytic stress increased their production of fetal Hb (HbF). Although the maximal in vivo HbF levels attained in 5 treated animals varied from 6.4-34.8%, their cultured bone marrow erythroid cells reverted to the fetal pattern of Hb synthesis. HbF synthesis is apparently modulated by the interaction of inhibiting and promoting factors, which is different among animals in vivo but equal in the cultures of their bone marrow erythroid cells.
