Abstract
Disclosed herein are methods of obtaining human hematopoietic cells from human pluripotent embryonic stem cells using mammalian stromal cells. Hematopoietic cells derived in this way are useful for creating cell cultures suitable for transplantation, transfusion, and other purposes.
Claims10
A method for obtaining human hematopoietic cells, comprising exposing a human pluripotent embryonic stem cell culture to mammalian hematopoietic stromal cells so as to thereby produce human hematopoietic cells, wherein at least some of the human hematopoietic cells that are so produced will form hematopoietic cell colony forming units if placed in methylcellulose culture.
A method for obtaining human hematopoietic cells, comprising exposing a human pluripotent embryonic stem cell culture in vitro to mammalian hematopoietic stromal cells so as to thereby produce human hematopoietic cells, wherein at least some of the human hematopoietic cells that are so produced will form erythroid blast forming units if placed in methylcellulose culture.
A method of transplanting human cells into a human recipient host, comprising:
- obtaining human hematopoietic cells which have been derived in vitro from a human pluripotent embryonic stem cell culture;
- obtaining a selected human cell other than hematopoietic cells, the selected non-hematopoietic cell having major histocompatibility complex compatibility to the human hematopoietic cells;
- and
- transplanting both the human hematopoietic cells and selected human non-hematopoietic cell into the human host.
