title: Lineage commitment and maturation induction in normal and leukemic preprogenitor cells.
abstract: Analysis of the critical cellular processes of self-generation, commitment, and maturation induction ideally requires the use of clonal cultures using cells with a capacity to undergo all three processes. Preprogenitor cells from normal mouse marrow are proving useful cells for such studies. Cells of a newly established cloned leukemic cell line, the GB2, are providing a useful analogous leukemic system because GB2 cells form stratified subpopulations of clonogenic cells able to be clonally analyzed in vitro in which self-renewal is demonstrable, but in which near-normal maturation can be induced by a wide range of hematopoietic regulators.
