Outgrowth expansion velocity at day 6 post-plating for mouse oral epithelium (mOrE), esophageal epithelium (mEsE) and bladder epithelium (mBlE) explants. Unpaired two-tailed Student’s t -test. n = 9, 29 and 33 explants from 3, 6 and 10 mice, respectively. P values: mOrE versus mEsE, 0.0049; mOrE versus mBlE, 2.7 × 10 −9 ; mBlE versus mEsE, 1.4 × 10 −7 . Red lines represent mean values.
