Study on the induction and differentiation of megakaryocyte progenitor cell derived from umbilical cord blood

摘要

Objective To build a protocol of separation and induction of megakaryocytes derived from cord blood mononuclear cells.Methods Red blood cells were precipitated by hydroxyethyl starch(HES).Mononuclear cells were obtained by density gradient centrifugation with Ficoll.The inducing efficiencies of megakaryocytes using different cytokine cocktails and culture media were analyzed.Results The best choice for erythrocyte sedimenta-
