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.
组织从损伤或应激中恢复的再生能力取决于干细胞的功能,但目前对于干细胞如何检测应激并启动适当反应的潜在机制仍知之甚少。在本期《临床研究杂志》中,赵(Cho)和优素福(Yusuf)等人证明,嘌呤能受体P2Y14可能介导造血干细胞和祖细胞的再生反应。
