  • Quantitative real-time PCR (qPCR) and immunofluorescence (IF) analysis are routinely included all markers in Figures 1 and 2. Reprogramming efficiency refers to alkaline phosphatase-positive clones with human embryonic stem cell (ESC) morphology. Neuronal differentiation for urinary induced pluripotent stem cells (UiPSC) clones not mentioned in Figure 3 was only assessed morphologically; as for cardiomyocyte differentiation, we only verified the generation of beating clusters. √, done; UC, urine cells; STR, single tandem repeat; EBs, erythroid bodies.
