Effect of a medium conditioned by CD34+ cells on proliferation of HUVECs.
HUVECs were cultured for 4 days in a HUVEC culture medium, serum-free medium (SFM), or serum-free medium conditioned by CD34+cells or BFU-E–, CFU-GM–, and CFU-Meg–derived cells. The experiment was repeated 3 times with similar results.
