Figure 5From: Establishment of transgene-free induced pluripotent stem cells reprogrammed from human stem cells of apical papilla for neural differentiationRT-PCR analysis of the expression of neural markers. The neurogenic induction followed the same method as that for samples shown in Figure 4. The SCAP are the original cells from which TF-SCAP iPSCs were derived. GAPDH was used to ensure equal loading of the samples. (+), presence of neurogenic induction medium; (-), regular culture medium without neurogenic induction. iPSCs, induced pluripotent stem cells; SCAP, stem cells from apical papilla; TF, transgene free.Back to article page
