title: Differentiation of chick blood island erythroblasts into erythrocytes and stability in long-term culture.
abstract: Clusters of 20-70 erythroblasts from blood islands of early chick blastoderm were cultured in serum-free chemically defined medium for a 3-month period. The erythroblast cluster produces erythroid cells and hemoglobins characteristic of the primitive and definitive erythroid cell lines. It seems there is a progenitor erythroid cell(s) in the erythroblast cluster which starts and/or continues maturing along various pathways of hemopoietic differentiation under simple culture conditions. The erythroid character of these cells is stable during the 3-month culture period.
