Method for inducing human blood-born hematospheres through aggregate culture and expanding blood adult stem cells and progenitor cells, and stem cell prepared by the same

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.
