Characteristics and analysis of normal and leukemic stem cells: current concepts and future directions.
Acute myeloid leukemias (AML) are considered to be clonal disorders involving early hematopoietic progenitor cells. The recent advances in characterization of early stem cells give rise to the question whether it is possible to distinguish healthy progenitors from cells of the leukemic clone in leukemia patients. Differences and similarities in phenotype, genotype and biology are described for leukemic cells and normal hematological progenitors. Recent new insights into human stem cell development offer the perspective that distinction between benign and malignant progenitors might be possible in the future at a very early stage of maturation.
