Tumor initiating cells (TICs) have been implicated in clinical relapse and metastasis of a variety of epithelial cancers, including lung cancer. While efforts toward the development of specific probes for TIC detection and targeting are ongoing, a universal TIC probe has yet to be developed. We report the first TIC‐specific fluorescent chemical probe, TiY, with identification of the molecular target
肿瘤起始细胞(TICs)与包括肺癌在内的多种上皮癌的临床复发和转移有关。尽管正在努力开发用于TIC检测和靶向的特定探针,但尚未开发出通用的TIC探针。我们报告了首个TIC特异性荧光化学探针TiY,该分子探针被鉴定为波形蛋白,波形蛋白是上皮-间质转化(EMT)的标记。TiY对分化的肿瘤细胞或正常细胞上的TIC进行选择性染色,并有助于可视化和富集来自患者肿瘤的功能活性TIC。在高浓度下,TiY还显示出抗TIC活性,对非TIC的毒性低。借助未开发的靶波形蛋白,TiY有望成为首个在各种癌症中检测TIC的通用探针。
