  • Title: [Effect of various factors on the differentiation of hematopoietic stem cells].
    Author: Golovanova TA, Kuralesova AI, Khorobrykh VV, Kaulen DR.
    Journal: Ontogenez; 1976; 7(2):203-7. PubMed ID: 1088374.
    Abstract:
    The treatment in vitro of bone marrow cells in mice by phytohemagglutinin, concanavaline, or antilimphocytic globulin resulted in the suppression of exogenous hemopoietic colonies in the spleen of lethally irradiated (830r) syngenic recipients, whereas lipopolysaccharide, tuberculin, anti-theta serum or nati-gamma-globulin serum exerted no influence on the colony-forming function of hemopoietic stem cells. The morphological analysis of the ratio and cell composition of hemopoietic colonies has revealed no marked differences between the experimental and control groups. The suppression of hemopoietic stem cells by mitogens might be due both to their direct effect and indirect one, possibly, through a humoral factor.
