纤维化是一种以大量细胞外基质替代实质组织为特征的病理过程,可导致器官功能障碍甚至死亡。成纤维细胞通常与纤维化和组织修复有关,很少与再生有关。然而,越来越多的证据支持不同器官中的成纤维细胞具有促进再生的作用。一些器官依靠成纤维细胞来维持干细胞的位置,而另一些器官则依靠成纤维细胞的活动,尤其是促进细胞黏附、迁移和增殖的分泌分子来引导再生过程。在这里,我们提供了纤维母细胞衍生的跨不同器官的再生信号的最新概述,并讨论了这种能力如何随着年龄的增长而受损。我们进一步介绍了一种基于将成人成纤维细胞恢复为胎儿/新生儿样表型的再生治疗的新范例。
Fibrosis is a pathologic process characterized by the replacement of parenchymal tissue by large amounts of extracellular matrix, which may lead to organ dysfunction and even death. Fibroblasts are classically associated to fibrosis and tissue repair, and seldom to regeneration. However, accumulating evidence supports a pro-regenerative role of fibroblasts in different organs. While some organs rely on fibroblasts for maintaining stem cell niches, others depend on fibroblast activity, particularly on secreted molecules that promote cell adhesion, migration, and proliferation, to guide the regenerative process. Herein we provide an up-to-date overview of fibroblast-derived regenerative signaling across different organs and discuss how this capacity may become compromised with aging. We further introduce a new paradigm for regenerative therapies based on reverting adult fibroblasts to a fetal/neonatal-like phenotype.
