Method for expansion of hematopoietic stem cells and progenitor cells using blood mononuclear cell sphere and stem and progenitor cells produced by the method

摘要

The present invention relates to a technique of using monocytic blood cells to effectively culture and proliferate blood adult stem cells and progenitor cells that only exist in small quantities to effectively obtain large quantities of stem cells. According to the present invention, the limitation of being able to derive only small quantities of stem cells from blood can be overcome, and the pluripotency of stem cells can easily be obtained.
