For many years there was a widely accepted picture of how a haematopoietic stem cell (HSC) gives rise to the multiple types of blood and immune cells. This described the general nature of stem and progenitor cells and the pathways of cell development. Recent years have seen many attempts to re-draw the map of haematopoiesis. These have become increasingly complex, and they often envisage multiples routes to some cell types. The 'established' view that self-renewal in haematopoiesis only occurs in HSCs has been challenged by the recognition of self-renewing HSC-derived progenitor cells that display at least some fate restriction. This evolution of how normal haematopoiesis is viewed has inevitable implications for understanding the origins, disease progression and classification of the leukaemias. In essence, some progenitor cells are now seen as possessing a larger repertoire of routes to end-fates than was previously thought. This leads one to ask whether leukaemia stem cells are equally or less versatile than their normal counterparts?
