Abstract: The invention provides serum-free, animal protein-free media formulations to be used in conjunction with hematopoietic growth factors for the in vitro growth of human neutrophil and megakaryocyte precursors. The medium is comprised of a base medium, corticosteriod, transferrin, insulin, cholesterol, ethanolamine, and human albumin. The invention also provides methods for preparing serum-free, animal protein-free suspensions of human hematopoietic precursor cells wherein the cellular component comprises at least about 16 % neutrophil precursors and at least about 1 % megakaryocyte precursors. Serum-free, animal protein-free suspensions of human hematopoietic cells are provided wherein the cellular component comprises at least about 30 %, preferably greater than 60 % neutrophil precursors. The neutrophil precursors are comprised of blast cells, promyelocytes, neutrophilic myelocytes, and neutrophilic metamyelocytes. Also provided are serum-free, animal protein-free cell suspensions wherein the cellular component comprises at least about 3 %, preferably greater than 8 % megakaryocyte precursors. Also provided are serum-free, animal-protein free cell suspensions wherein the cellular component comprises colony-forming units and cluster-forming units.
