Recent Advances in Cell Biology of Acute Leukemia

The development of new techniques such as immuno­ phenotyping, cytogenetic investigations and, more recently, molecular studies has considerably increased our diagnostic repertoire and broadened our ideas about the biology of acute leukemias. While immunophenotyping with mono­ clonal antibodies has yielded increased diagnostic precision and made it possible to develop a highly reproducible classification of acute leukemias based on cell-biological features, further insights have been gained in
