胚胎干细胞(ESCs)在功能细胞类型的再生和临床应用方面具有巨大的治疗前景。然而,干细胞在移植宿主中的致瘤潜力仍然是一个主要障碍。在本期JCI中,Cui及其同事将TCF 7介导的经典WNT信号转导确定为ESC衍生的视网膜祖细胞(ESC-RPC)的致瘤性和治疗功能的关键决定因素。他们的研究结果表明,解决关键的细胞外信号和相关的内在因素将是成功使用ESC衍生的祖细胞移植的关键。
Embryonic stem cells (ESCs) hold great therapeutic promise for the regeneration of functional cell types and clinical applications. However, tumorigenic potential of stem cells in a transplanted host remains a major obstacle. In this issue of the JCI, Cui and colleagues identified TCF7-mediated canonical WNT signaling as a critical determinant of both the tumorigenicity and therapeutic function of ESC-derived retinal progenitor cells (ESC-RPCs). Their findings suggested that addressing key extracellular signaling and related intrinsic factors will be essential for the successful use of ESC-derived progenitor transplantation.
