Circulating tumor cell (CTC) clusters have an enhanced capacity to initiate metastases, compared with single cells, but it is unclear how they gain such advantage. A recent study by Gkountela etal. (Cell 2019;176:98-112) links the physical state of clusters with increased accessibility of stem cell-related transcription factors, providing novel insights into the epigenetic regulation of 'stemness' in CTC clusters.
循环肿瘤细胞(CTC)簇与单个细胞相比,具有更强的转移起始能力,但目前尚不清楚它们如何获得这种优势。Gkountela 等人最近的一项研究(Cell 2019;176:98-112)将簇的物理状态与干细胞相关转录因子的可及性增加联系起来,为 CTC 簇中“干性”的表观遗传调控提供了新的见解。
