Bovine erythrocytic, granulocytic and macrophage colony formation in culture. A preliminary report
Kaaya Godwin P.; Valli VE.; Maxie M G. (University of NaitrobiSchool of Biological Sciences, 1978-07)Bovine erythrocytic colonies containing up to 300 cells each were produced by using a plasma clot technique with five percent CO2 at 37 degrees C. with high humidity and 2.5 units of sheep step III erythropoietin per ... -
Bovine granulocyte/macrophage and erythroid colony culture: characteristics of the colonies and the assay systems
Kaaya Godwin P.; Maxie MG.; Valli VE.; Losos GJ. (University of Nairobi.School of Biological Sciences, 1979-10)Bovine bone marrow granulocyte/macrophage colonies were cultured in vitro in methyl cellulose and in plasma clots using bovine endotoxin-stimulated serum as a source of colony stimulating activity. The endotoxin-stimulated ... -
Cryopreservation of bovine hemopoietic progenitor cells in liquid nitrogen
Kaaya Godwin P.; Maxie MG.; Valli VE. (University of Nairobi.School of Biological Sciences, 1981-04)Bovine marrow granulocyte/macrophage and erythroid progenitor cells maintained viability after storage in liquid nitrogen for 2 to 4 weeks. The granulocyte/macrophage progenitor cells maintained 100% viability for 4 weeks, ... -
Inhibition of bovine bone marrow granulocyte/macrophage colony formation in vitro by serum collected from cattle infected with Trypanosoma vivax or Trypanosoma congolense
Kaaya Godwin P.; Valli VE.; Maxie MG.; Losos GJ. (University of Nairobi.School of Biological Sciences, 1979-06)Serum collected from cattle infected with Trypanosoma vivax or Trypanosoma congolense inhibited bovine granulocyte/macrophage colony formation in methyl cellulose cultures. Maximum inhibition was caused by serum collected ... -
Inhibition of leukopoiesis by sera from Trypanosoma congolense infected calves: partial characterization of the inhibitory factor
Kaaya Godwin P.; Tizard IR.; Maxie MG.; Valli VE. (University of Nairobi.School of Biological Sciences, 1980-06)Sera collected from calves infected with Trypanosoma congolense inhibited bovine granulocyte/macrophage colony formation in vitro, but not erythroid colony formation. The inhibitor was found to be TCA precipitable in nature ...
