doi: 10.1093/nar/gkaf1490
Figure Lengend Snippet: Hnrnpf KO compromises ESC proliferation. ( A ) Schematic illustration of the experimental design to knock out Hnrnpf . Yellow lines show the recognition sites of sgRNAs. Red arrows are PCR primers for genotyping.Validation of two Hnrnpf KO ESC clones by genotyping PCR ( B ) and western blot ( C ). ( D ) Reduced proliferation rate of Hnrnpf KO ESCs. ( E ) Cell cycle analysis of E14 and Hnrnpf KO ESCs. ( F ) Colony formation assay of E14 and Hnrnpf KO ESCs. Representative phase-contrast and AP staining images are shown. Scale bar: 500 µm. The colony number ( G ) and diameter ( H ) of E14 and Hnrnpf KO ESCs are shown in panel (F). Data are presented as average ± SD ( n = 3 biological replicates). Statistical analysis was performed with student’s t -test. *, P < .05; **, P < .01; ***, P < .001.
