Hematopoietic Stem Cells Expansionin Rotating Wall Vessel

1 IntroductionClinical trials have demonstrated that ex vivo expanded hematopoietic stem cells (HSCs) and progenitors offer great promise in reconstituting in vivo hematopoiesis in patients who have undergone intensive chemotherapy. It is therefore necessary to develop a clinical-scale culture system to provide the expanded HSCs and progenitors. Static culture systems such as T-flasks and gas-permeable blood bags are the most widely used culture devices for expanding hematopoietic cells. Bu…
