Figure Lengend Snippet: ( A ) Schema showing the process for generating PPDO. ( B – E ) Brightfield microscopy images of early passage PPDO and HPDO from Em- ( B ), EPN ( C ), LPN ( D ) and from a human donor ( E ). Scale bar: 500 µm. ( B’ – E’ ) Brightfield microscopy images of late passage PPDO and HPDO from Em ( B’ ), EPN ( C’ ), LPN ( D’ ) and from a human donor ( E ). Scale bar: 500 µm. ( F – H ) Single-plane confocal images of PPDO derived from EPN pig pancreas immunostained against CFTR-Phalloidin-PDX1 ( F ), SOX9-GP2-NKX6-1/GCG ( G ), KRT7-CDH1 ( H ) and counterstained with DAPI. Insets show the individual channels of the merge image. PPDO were stained at passage 3. Scale bar: 50 µm. ( I – K ) Brightfield microscopy images of early passage Em PPDO at the beginning of the live imaging, treated with DMSO ( I ), forskolin ( J ), and secretin ( K ). Scale bar 500 µm. ( I’ –K’ ) Brightfield microscopy images of early passage Em PPDO at the end of the live imaging, treated with DMSO ( I’ ), forskolin ( J’ ) and secretin ( K’ ). Scale bar 500 µm. ( L ) Quantification of the lumen area expansion of PPDO following 4 h of live imaging and treatments with forskolin and secretin. n = 3 independent experiments with different PPDO lines (1 Em, 1 EPN and 1 Ad). Data are shown as mean ± SD. One-way ANOVA followed by Dunnett’s multiple comparisons test was used to assess significance. P val are: * Padj = 0.015 for DMSO vs forskolin and * Padj = 0.0140 for DMSO vs secretin. ( M ) Quantification of the lumen area expansion of HPDO following 4 h of live imaging and treatment with forskolin. n = 4 independent experiments with 4 HPDO lines. Data are shown as mean ± SD. Mann–Whitney test was used to assess significance. * P = 0.0286. .
