C19MC accelerates iPSC generation when co-transfected with Yamanaka factors. (a) Schematic of transfection protocol. 759, sgRNA-759/SAM; Y4, Yamanaka factors. (b) Colony counts from 759-, Y4- and 759+Y4-transfected NHDFs at day 24. (c,d) Colony morphology at 10 days post transfection (c) or AP staining of iPSC clones at day 24 (d) of Y4- or 759+Y4-transfected NHDFs. (e,f) Image (e) and qRT-PCR analysis of the indicated genes normalized to GAPDH (f) of embryoid bodies (EB) generated from 759+Y4 iPSC clone 3-CF-6 (passage 5) after 7 days culture in suspension compared to the parental non-differentiated iPSC clone. (gi) Images of teratoma sections from SCID mice injected with iPSCs generated using 759-sgRNA/SAM +Y4, immunostained with human mitochondria specific antibody and hematoxylin showing ectoderm, mesoderm and endoderm like cellular structures. Graph represents means ± SEM. *p < 0.05 vs. Y4 (b) or non-differentiated iPSC 3-CF-6 clone (f). Two way ANOVA with Dunnett’s post-hoc (b); Multiple t-tests with Holm-Sidak correction (f).
