Objective:
To observe the inductive efficiency of deriving hematopoietic colony-forming cells from murine embryonic stem (mES) cells co-cultured with bone marrow stromal cell-conditional medium (mBMEC-CM).
Methods:
After the day-4 embryoid bodies (4 dEBs) were derived from embryonic stem cell-D3 (ES-D3) cells, the cells of 4 dEBs were induced into hematopoietic colony-forming cells by co-culturing with mBMEC-CM. The numbers of 4 dEB-derived hematopoietic colonies (high proliferation potential-colony formation cells and burst forming unit-erythroid, HPP-CFC and BFU-E) were detected to explore the relation between the implanted 4 dEB-derived cell numbers and the colony numbers of BFU-E and HPP-CFC. The inducing effect of mBMEC-CM was observed according to the doses and days of induction.
Results:
The number of 4 dEB-derived cells within 1 x 10(7)-4 x 10(7)/L was positively related to the colony numbers of HPP-CFC and BFU-E (HPP-CFC, r=0.916,P< 0.05; BFU-E, r=0.927, P<0.05). The inducing doses of mBMEC-CM within 0-20% were positively related to the colony numbers of HPP-CFC and BFU-E (HPP-CFC, r=0.909, P<0.05; BFU-E, r=0.927, P<0.01). The colony numbers of HPP-CFC and BFU-E derived from the 4 dEB-derived cells were the highest after 3 days of induction, followed by those of 6 days and 9 days.
Conclusion:
Bone marrow endothelial cell-conditional medium can promote the generation of HPP-CFC and BFU-E from murine embryonic stem cells.
