Studies on the relationship between leukemic fibroblast colony forming cell and hemopoietic cells

Abstract

36 patients with leukemia, including AML, CML and ALL were studied. Fibroblast colony forming cells (CFU-F) in patients with different types of leukemia were less than in normal adults (P<0.05-0.001). There was no correlation observed between CFU-F and CFU-Mix/L-CFU in normal adults and leukemic patients (P>0.05). It was found that CFU-F is a single clone not, originating from hemopoietic cells. After fetal muscular conditioned media were added, we observed that myelogenous leukemic cells showed the ability to adhere to the bottom of the dish, indicating the existence of quantitative and qualitative defects of CFU-F in leukemia. The mechanism and clinical significance of this phenomenon are discussed.
