title: A new look at the haemopoietic response to cytotoxic agents and stem cell regulation.
abstract: A re-evaluation of the response of haemopoietic stem cells, in mice, to radiation and anticancer drugs suggests a precise mechanism for the regulation of the number of stem cells through a control of their rate of differentiation. This analysis which has some counter-intuitive aspects, appears to be the first attempt to obtain a unified explanation for various effects of cytotoxic agents and has some important biological and clinical implications.
