In descriptions of stem cell differentiation, transitional, proliferating cells that are descendants of stem cells and that give rise to one or more mature, differentiated cell lineage(s). Transit cells have properties intermediate between stem cells (q.v.) and differentiated cells, as well as the plasticity to behave like one or the other of these cell types in response to specific environmental signals. Also called transit amplifying cells.
