Figure Lengend Snippet: Growth of proliferative 2D monolayer of murine epithelium on surface of collagen hydrogel. ( A ) Workflow for subculturing 2-D monolayers. Monolayers are dissociated from collagen and split. Brightfield images ( bottom ) show cell preparation at different workflow stages. ( B ) Time lapse fluorescence (DsRed) images of crypt-derived cells on collagen at passage number 0 (P0, crypts) and passage number 5 (P5). Scale bar =100 μm. ( C ) Karyotype analysis of 2-D monolayer at passage number 5 showing a normal karyotype. ( D ) SEM image of monolayer on collagen gel at day 3 of culture. ( E ) Fluorescence image of cross section through the monolayer immunostained for actin ( green ) and β-catenin ( red ). Distribution of β-catenin (an intracellular protein) demonstrated columnar-shaped cells with height of 9.4 ± 0.8 μm and width of 7.5 ± 0.9 μm (n = 10). ( F ) High magnification view of subregion of ( D ). ( G ) High magnification view of subregion of ( E ). ( H ) Staining for ZO-1, E-cadherin, or occludin (red) ; villin or actin (green) ; integrin-β4 and NA + /K + -ATPase (red) . Nuclei (blue) .
