Do We Have a Workable Clinical Protocol for Differentiating Lympho-Hematopoietic Stem Cells from the Source of Embryonic Stem Cells and Induced Pluripotent Stem Cells in Culture?

Abstract

In recent years, many researchers are focusing on deriving lympho-hematopoietic stem cells (L-HSC) from human embryonic stem cells (ESC) and/or induced pluripotent stem cells (iPSC) in culture as alternative sources for transplantation. Two protocols are available for research purposes: mouse stroma cell line coculture system and embryoid bodies (EBs) suspension culture system. However, due to the lack of human stroma cell line, which could support the derivation of L-HSC in culture, the generation of therapeutic lympho-hematopoietic cells for clinical purpose can only be achieved using EBs suspension culture system. In this short communication/review, the results of EBs suspension culture system using mouse and human ESC/iPSC are summarized and the potential clinical application is discussed. Copyright
