Abstract

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 the JCI, Cho and Yusuf et al. demonstrate that the purinergic receptor P2Y₁₄ may mediate the hematopoietic stem and progenitor cell regenerative response.
