摘要

成体干细胞通过产生分化细胞维持组织稳态。最近的大量研究表明，干细胞本身是可以通过去分化过程被替代的。去分化的能力和机制在不同的物种和器官环境中差异很大。然而，一些核心特性通常是存在的。在这篇综述中，我们总结了去分化的“特征”，包括维持效力、丧失感觉和迁移的机制，并回顾了目前对去分化作为一种真正的替代机制的理解。

Rewinding the clock: mechanisms of dedifferentiation

Adult stem cells maintain tissue homeostasis through the production of differentiating cells. Considerable recent work has identified that stem cells themselves are replaceable through the process of dedifferentiation. The capacity and mechanisms of dedifferentiation vary widely among species and organ contexts. However, some core features are commonly present. In this review, we summarize ‘hallmarks’ of dedifferentiation, including mechanisms for maintenance of potency, sensation of loss, and migration, and review the current understanding of dedifferentiation as a true replacement mechanism.

期刊介绍： Current Opinion in Genetics and Development aims to stimulate scientifically grounded, interdisciplinary, multi-scale debate and exchange of ideas. It contains polished, concise and timely reviews and opinions, with particular emphasis on those articles published in the past two years. In addition to describing recent trends, the authors are encouraged to give their subjective opinion of the topics discussed. In Current Opinion in Genetics and Development we help the reader by providing in a systematic manner: 1. The views of experts on current advances in their field in a clear and readable form. 2. Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.[...] The subject of Genetics and Development is divided into six themed sections, each of which is reviewed once a year: • Cancer Genomics • Genome Architecture and Expression • Molecular and genetic basis of disease • Developmental mechanisms, patterning and evolution • Cell reprogramming, regeneration and repair • Genetics of Human Origin / Evolutionary genetics (alternate years)
