The regenerative capacity of tissues to recover from injury or stress is dependent on stem cell competence, yet the underlying mechanisms that govern how stem cells detect stress and initiate appropriate responses are poorly understood. In this issue of theJCI, Cho and Yusuf et al. demonstrate that the purinergic receptor P2Y14 may mediate the hematopoietic stem and progenitor cell regenerative response.
