hurdle in stem cell therapy is the tumorigenic risk of residual undifferentiated stem cells. This report describes the design and evaluation of synthetic hybrid molecules that efficiently reduce the number of human induced pluripotent stem cells (hiPSCs) in cell mixtures. The design takes advantage of Kyoto probe 1 (KP‐1), a fluorescent chemical probe for hiPSCs, and clinically used anticancer drugs
干细胞治疗的主要障碍是残留未分化干细胞的致瘤风险。该报告描述了可有效减少细胞混合物中人类诱导的多能干细胞(hiPSC)数量的合成杂交分子的设计和评估。该设计利用了京都探针1(KP-1),hiPSC的荧光化学探针和临床使用的抗癌药物。在我们合成的KP-1-药物偶联物中,我们发现了一种异常选择性的,化学上易处理的分子,该分子诱导了hiPSC的死亡。机理分析表明,高选择性源于转运蛋白介导的外排与细胞毒性作用模式的协同结合。本研究为设计选择性,安全,
