  • Title: Specific thrombopoietic inhibition by syngeneic platelet homogenates.
    Author: Krizsa F, Kelemen E, Cserhati I, Lajtha LG.
    Journal: Biomedicine; 1977 Jun; 27(4):145-8. PubMed ID: 890022.
    Abstract:
    Injections of 1 to 2.5 X 10(8) syngeneic, uninjured platelets did not diminish the circulating platelet count nor the bone marrow megakaryocyte content in mice, and did not influence the incorporation of 75selenomethionine into circulating platelets. However, platelet homogenates, prepared by repeated freezing and thawing of identical amounts of syngeneic paltelets induced a dose-dependent thrombocytopenia along with a diminution on bone marrow megakaryocyte content, and a decrease in 75 selenomethionine incorporation. Other circulating blood cell counts were not diminished after platelet homogenates, and three intravenous doses of homogenates prepared from 0.7 to 1 X 10(5) syngeneic buffy coat cells failed to influence circulating platelet count or 75 selenomethionine incorporation.
