title: Friend leukemia: rapid development of erythropoietin-independent hematopoietic precursors.
abstract: Infection of mice with the polycythemia-inducing strain of Friend leukemia virus caused a rapid emergence of new erythroid precursor cells. These cells which, in the absence of erythropoietin, proliferated in vitro to form colonies and even differnetiated, quickly out-numbered the usual erythropoietin-dependent hematopoietic elements in bone marrow and spleen. Ultimately, the marrow and spleen were probably totally repopulated with this erythropoietin-independent cell.
