In this issue of the Journal, Stroo et al. [1] published their findings on the engraftment of the intact and ischaemic kidney by haematopoietic stem cells (HSC). Specifically, these investigators demonstrated that systemically administered HSC preferentially migrate to the ischaemic kidney and that this process is SDF-1/CXCR4 independent. Indeed, ischaemia-induced retention of hypoxia-inducible factor-1 has been implicated in such a preferential migration to ischaemic areas, although induction of SDF-1 was believed to be necessary [2]. This requirement for SDF-1 chemokine is overridden in leukaemic
