title: Pluripotential stem cell replication in continuous human, prosimian, and murine bone marrow culture.
abstract: Prolonged replication of pluripotential stem cells and committed progenitor cells is sustained for prolonged periods in a murine marrow culture system. Alterations in stem cell replication and differentiation are observed after infection of the cultures with Friend virus and Kirsten sarcoma virus consistent with transformation of pluripotential stem cells in the first case and transformation of the macrophage component of the hemopoietic microenvironment in the second. Prolonged myelopoiesis and CFU-c proliferation was also observed in continuous human and prosimian marrow cultures, suggesting the applicability of this technique for analysis of stem cell control and in vitro leukemogenesis in species other than the mouse.
