Will the hematopoietic progenitor cells proliferate in Hematopoietic Progenitor Cell Expansion Medium XF (C-28021) without Cytokine Mix E (C-39890)?

For the expansion of hematopoietic progenitors (CD133+ cells; CD34+ cells); PromoCell has developed Hematopoietic Progenitor Cell Expansion Medium XF (C-28021); a serum-free and xeno-free formulation. The medium must be supplemented with either Cytokine Mix E (C-39890) or with the user's own mixture of cytokines. Cytokine Mix E is a ready-to-use mix containing recombinant human TPO; SCF; flt3-ligand; and IL-3. The strong expansion of the progenitor cells in Expansion Medium XF + Cytokine Mix E persists for at least two weeks; resulting in a 200-300x increase of the cell number with only 20-30% differentiated cells. Note: If starting with CD133+ cells; the CD133 marker is getting lost during this expansion step. The resulting cells are D34⁺/CD38^-/CD133^-.
