Fetal liver CD36+ Early Erythroid Progenitor cells are derived from FL-CD34+ cells in culture. Fetal liver-CD34+ cells are isolated from fetal liver Mononuclear Cells with a purity ＆gt;90％. FL-CD34+ cells are cultured for seven to eight days using a serum free expansion media for hematopoietic cells, with the addition of EPO （5U/ml）, SCF （50ng/ml）, IL-3 （10ng/ml）, and IL-6 （10ng/ml） growth factors. The cells are harvested from culture, and the CD36+ cells are positively isolated, using immunomagnetic CD36 MicroBeads.
