THY1在鼠标)。虽然从重新编程鸡尾酒最小化省略cMyc的风险不受控制的增殖,其排斥导致在重编程效率倍减量。因此,具有取代的cMyc转基因的可行性(非整合型)重组的“PTAT-mcMyc”蛋白质递送进行评价,而不损害重编程效率或该多能性表型。纯化和semisoluble /颗粒PTAT-mcMyc的输送保持的Oct4-GFP+集落形成(即,重编程效率),而通过各种标准支持多能性。Differential repression of Thy1 by pTAT-mcMyc ± Oct4, Sox2, and Klf4 (OSK) suggested differential (and non-additive) mechanisms of repression. Extending these findings, attempts to enhance reprogramming efficiency through a staggered approach (prerepression of Thy1) failed to improve reprogramming efficiency. We consider protein delivery a useful tool to decipher temporal/molecular events characterizing somatic cell reprogramming.
