1. A method of producing megakaryocytes, comprising:
extracting cells from a tissue of a donor, wherein the tissue is selected from the group consisting of blood and bone marrow;
isolating CD14+/CD34 monocytes from the extracted cells; and
culturing the isolated CD1430/CD34 monocytes in vitro in the presence of thrombopoietin (TPO) for a sufficient time to permit differentiation of the CD14+/CD34 monocytes into megakaryocytes.
