- FIGURE 2 Characterization of CCM1 +/- and clonally expanded CCM1 -/- BOECS. (A) CCM1 -/- BOECs were established by limiting dilution of the CRISPR/Cas9 RNP-treated cell pool and clonal expansion of single cells (created with BioRender.com). (B) Shown are the genotypes of CCM1 -/- BOEC clones included in this study. All variants either lead to a frameshift or a premature stop codon (additional information on the CRISPR/Cas9-induced mutations and numbers of individual clones are given in Supplementary Table S1 ). (C) CCM1 -/- BOECs presented a more compact morphology in brightfield microscopy and increased tube formation. The largest cell diameter and the number of meshes formed on Matrigel-coated plates were quantified. Scale bar indicates 400 um. Data are presented as single data points with the mean ( n = 4-6). (D) Immunofluorescence staining revealed a higher number of intercellular gaps (white arrowheads), more actin stress fibers, and a higher expression of KLF2 and KLF4 in CCM1 -/- BOECs. Representative images are shown. Scale bar indicates 100 um. Individual data points are shown with the mean ( n = 3-5). Student's t test was used for statistical analysis: * p < 0.05; ** p < 0.01; **** p < 0.0001; ns = not significant; VE-cadherin = vascular endothelial cadherin.
