Abstract
The use of chromosome-banding techniques to identify metaphase chromosomes in hematopoietic colonies derived from marrow cultures from patients with acute nonlymphocytic leukemia (ANLL) offers an opportunity to study the extent of involvement of progenitor cells in the leukemic process. Several lines of evidence have demonstrated that chronic myelogenous leukemia is a clonal hematopoietic stem-cell disorder.1 The Philadelphia chromosome, detectable in 90 per cent of patients with chronic myelogenous leukemia, has been found in colonies grown from committed granulocyte and erythroid progenitors in vitro.2,3 Other studies have used female patients who were heterozygous for the X-chromosome-linked enzyme glucose-6-phosphate dehydrogenase. Both forms.
