High-Efficiency Differentiation of Human Pluripotent Stem Cells to Hematopoietic Stem/Progenitor Cells in Random Positioning Machine Bioreactors.

Human pluripotent stem cells (PSCs) are known to differentiate into almost all the blood lineage cells in vitro and hold a great promise for studying human early hematopoietic development and have a huge potential in the treatment of hematological disorders. Although several methods of hematopoietic stem/progenitor cell (HSPC) differentiation have been developed, the HSPC yields achieved using these strategies are not yet available for clinical application. Recently, bioreactor-based devices and biochemical factors synergistically have been used to induce hematopoietic differentiation and showed a potential role in hematopoiesis. This chapter describes a protocol for using a random positioning machine bioreactor to culture human PSCs and the large-scale production of HPCs. Techniques for characterizing the differentiated cells and assessing the efficiency of hematopoietic differentiation in the bioreactor with immunostaining and flow cytometry are also presented. © 2021.
