The slow kinetics and low efficiency of reprogramming methods to generate human induced pluripotent stem cells (iPSCs) impose major limitations on their utility in biomedical applications. Here we describe a chemical approach that dramatically improves (>200 fold) the efficiency of iPSC generation from human fibroblasts, within seven days of treatment. This will provide a basis for developing safer, more efficient, non-viral methods for reprogramming human somatic cells.
人类诱导多能干细胞(iPSCs)生成的方法动力学缓慢且效率低,限制了它们在
生物医学应用中的实用性。在这里,我们描述了一种
化学方法,可显著提高从人类成纤维细胞生成iPSC的效率(提高了200倍以上),并在治疗后七天内完成。这将为开发更安全、更高效、非病毒方法重新编程人类体细胞奠定基础。
