Radiosensitivity of macrophage colony-forming cells-implications for their heterogeneity.
We compared the radiosensitivity of macrophage (M) colony-forming cell (CFC) in and outside the hemopoietic bone marrow. Murine bone marrow cells (BMC) are stimulated by either macrophage colony-stimulating factor (CSF-1) or murine recombinant granulocyte-macrophage colony-stimulating factor (rGM-CSF) to form M- and granulocyte- macrophage (GM) colonies on soft agarose medium, whereas both peri...
متن کاملHematopoietic colony-forming cells derived from human embryonic stem cells.
Human embryonic stem (ES) cells are undifferentiated, pluripotent cells that can be maintained indefinitely in culture. Here we demonstrate that human ES cells differentiate to hematopoietic precursor cells when cocultured with the murine bone marrow cell line S17 or the yolk sac endothelial cell line C166. This hematopoietic differentiation requires fetal bovine serum, but no other exogenous c...
متن کاملHeterogeneity of Antibody-forming Cells
Cell suspensions from draining lymph nodes of immune and nonimmune rats were reacted in vitro with (125)I-labeled antigens. In light microscopic radioautographs of smears, 17% of the immunized cells were tagged by specific antigen; 2.0% of control cells were positive. In electron microscopic radioautographs, 90% of the labeled elements from immune donors were lymphocytes, blast and plasma cells...
متن کاملCrossreaction of antilymphocyte globulin with human granulocyte colony-forming cells.
Clinical preparations of horse antilymphocyteglobulin (ALG) were found to inhibit human bone marrow granulocyte colony growth. This effect was enhanced by complement and was dose dependent, being almost complete at ALG concentrations of 100 microgram/ml. Inhibition was a property of ALG but not of normal horse globulin. However, short incubation of ALG with bone marrow cells occasionally stimul...
متن کاملColony forming cell assays for human hematopoietic progenitor cells.
Hematopoietic stem cells (HSCs) present in small numbers in adult bone marrow (BM), peripheral blood (PB) and umbilical cord blood (CB) produce a heterogeneous pool of progenitors that can be detected in vitro using colony forming cell (CFC) assays. Hematopoietic progenitor cells proliferate and differentiate to produce colonies of maturing cells when cultured in a semisolid methylcellulose-bas...
