Abstract

Tranferrin has been shown to have cytoprotective functions. The aim of this study was to evaluate the effect of antibody against CD71 (transferrin receptor) on survival potential of erythroid progenitor cells. After anti-CD71 IgG or control IgG was reacted with cells for 20 min on ice, the uptake of transferrin-bound 59Fe by the MEL cells or the mouse bone marrow cells during 2-day incubation without erythropoietin was measured. Erythropoiesis was evaluated by addition of erythropoietin after 4-5 weeks' culture without erythropoietin or β-mercaptoethanol, and production of cells containing hemoglobin was compared by immunocytological methods. MEL cells reacted with anti-CD71 IgG incorporated more transferrin-bound 59Fe than MEL cells reacted with control IgG. Uptake of transferrin-bound 59Fe by mouse bone marrow cells reacted with anti-CD71 IgG was also greater than by cells reacted with control IgG. Erythrocytes developed from cells reacted with anti-CD71 IgG and cultured for 4-5 weeks, but few erythrocytes developed from cells reacted with control IgG. Bone marrow cells depleted of TER119+ cells, CD34+ cells, or CD45+ cells and reacted with CD71 antibody did not differentiate into erythrocytes. Survival potential of erythroid progenitor cells were enhanced by reaction with anti-CD71 antibody.
