The aim of this study was to investigate the effect of GW003 on the ability of granulocyte colony forming in vitro of bone marrow cells. The bone marrow samples was collected from normal rhesus, the patients with leukemia in stages of remission and chemotherapy respectively, and the nucleated cells were separated and cultured for 12 days after addition of different concentrations of GW003 or rhG-CSF, or G-CSF mutant. Then the amount of colony-forming unit-granulocyte-macrophage was counted. The results indicated that GW003 could enhance the ability of bone marrow nucleated cells of rhesus to forming CFU-GM in vitro, and its effect was much better than that of rhG-CSF or G-CSF mutant at the same concentration(®). The GW003 showed dose-response relationship to CFU-GM level (r = R(2) = 0.965, P = 0.003, in a certain concentration), the GW003 also could enhance CFU-GM formation of marrow nucleated cells in leukemic patients, especially for patients receiving chemotherapy. The GW003 could relieve the marrow suppression caused by chemotherapy significantly. It is concluded that the GW003 can significantly improve the ability of bone marrow cells to form granulocyte colony in vitro as well as effectively alleviate bone marrow suppression.
