Abstract
Studies on the hemopoietic colonies (CFU-C, BFU-E and CFU-E) were performed with bone marrow cells and peripheral blood in a patient with chronic myelogenous leukemia of the juvenile type (J-CML).
In the bone marrow, hemopoietic colonies of earch type were grown within a normal limit as compared with healthy subjects. Before treatment, a remarkable number of CFU-C was seen.
In a serial study, the appearance of these progenitor cells in peripheral blood of a patient seemed to be related to viral infection and chemotherapy.
A positive relationship was observed between BFU-E and reticulocyte count.
A large number of colony forming cells in the stage of DNA synthesis were observed in this case as seen those of adult type of CML.
