A) Schematic representation of human CYFIP1 expression vector. B) qPCR quantification of CYFIP1 transcript levels in independent transgenic CYFIP1-GoF hESCs lines (TG#1 -10) and parental H7 cells (CTRL) at undifferentiated state. Data were normalised to the CTRL which was set as 1. C) qPCR analysis of CYFIP1 transcript during neuronal differentiation. Data shown are the mean between clones #3 and #5, all normalised to the CTRL cells at d5 of neuronal differentiation. D) Western blot confirming increased CYFIP1 protein level in CYFIP1-GoF cells (Clone #3) throughout 50 days of neuronal differentiation. Quantitative data on the right panel represent the average of clones #3 and #5. E) Schematic of CYFIP1 gene locus highlighting the first exon where gRNA sequences were designed. For space reasons, the sequence of the insertion present in one of the alleles of clone#70 is not reported and is indicated as “--200bp--”. F) DNA sequence flanking the edited site in the wild-type and edited CYFIP1 locus. G) Western blot demonstrating reduced CYFIP1 protein levels in 3 of the targeted clones (CYFIP1 clone#31, clone#41 and #70) compared to the parental line (CTRL).
