Polynucleated megakaryocytic cell and method for manufacturing platelets

摘要

An object of the present invention is to provide a method of promoting polynucleation of megakaryocytic cells to form polynucleated megakaryocytic cells with higher polynucleation, and to provide a method for efficiently producing platelets from polynucleated megakaryocytic cells. The present invention is a method for producing polynucleated megakaryocytic cells, wherein the method includes a step for inducing forced expression of an apoptosis suppressor gene in megakaryocytic cells prior to polynucleation and culturing of these cells.
