Figure Lengend Snippet: Schematic of patient‐derived intestinal organoid acquisition and expansion followed by two functional assays. Created with BioRender.com. qPCR Validation of lentivirus‐mediated shRNA knockdown of FGL2 and CFTR in intestinal organoids. Significance of sample differences was calculated using the one‐tailed student t ‐test ( n = 2 biological replicates). All values are mean ± SD. EV = empty vector. Representative confocal microscopy images of calcein green labelled FIS organoids of a healthy individual and a CF patient, before and 60 min after stimulation with Fsk (5 µM). Scale bar, 200 μm. Quantification of FIS response in wt‐CFTR organoids (ORG‐01(HC)) shown in (C) as area under the curve at 60 min. Significance of sample differences was calculated using two‐way ANOVA ( n = 2 biological replicates). All values are mean ± SD. Quantification of FIS response in F508del‐CFTR organoids (ORG‐BX‐002 (dF/dF)) shown in (C) as area under the curve at 60 min. Significance of sample differences was calculated using two‐way ANOVA ( n = 2 biological replicates). All values are mean ± SD. Tracing of Ussing chamber measurements of the transepithelial current produced by 2D monolayer cultures of specified organoids. The F508del‐homozygous monolayers with the knockdowns have been rescued with Trikafta.
