Summary Pluripotent stem cells (CFU-GEMM) give rise to multilineage hemopoietic colonies in culture. The cellular composition revealed that mixed colonies contain cells of different myeloid lineages and mononuclear cells with T-cell surface antigens. T-lymphocytes of primary colonies, replated secondary and tertiary colonies from a patient with Hodgkin's Lymphoma were identified by their reaction with the monoclonal antibody OKT 8. Evidence for a common progenitor of myeloid and lymphoid cells is provided by analysis of individual secondary and tertiary colonies using OKT 3, OKT 4, OKT 8, VIM-D 5, and Ig M + D antibodies for each individual colony. Primary mixed, replated secondary and tertiary colonies revealed OKT 8 positive cells. No reaction with OKT 3, OKT 4, VIM-D 5, OR Ig M+D was observed.
