Figure Lengend Snippet: Schematic illustration of 3D co‐culture setup using AEC‐tLgT epithelial cells and MLg mouse fibroblasts. Epithelial cells and fibroblasts are mixed with Matrigel and loaded onto Transwell filters and provided nutrients through medium perfusion from the outside chamber. GFR, growth factor‐reduced; PET, polyester.

Figure Lengend Snippet: Representative data and images for CSC‐ and NiCl 2 ‐treated AEC‐tLgT cells. ( A ) RT‐qPCR was used to measure induction of xenobiotic response‐related genes CYP1A1 and CYP1B1 after 48 hr CSC treatment of AEC‐tLgT cells. mRNA abundance was normalized to actin ( ACTB ) levels and fold change was calculated over DMSO vehicle‐treated samples. N = 3. Values shown as mean ± SD . ( B ) Representative brightfield images at 4× magnification of vehicle‐ and CSC‐treated samples showing progressive morphological changes with increasing CSC dose. ( C ) Representative RT‐qPCR results for vehicle‐ and nickel (NiCl 2 )‐treated AEC‐tLgT cells after 48 hr showing induction of metal response genes CA9 and NDRG1 . mRNA abundance was normalized to MTF1 levels and fold change was calculated over water vehicle‐treated samples. N = 3. Values shown as mean ± SD . ( D ) Representative brightfield images at 4× magnification of vehicle‐ and NiCl 2 ‐treated samples showing stable cell survival across NiCl 2 .
