Fig. 2From: Wnt signaling regulates trans-differentiation of stem cell like type 2 alveolar epithelial cells to type 1 epithelial cellsGene expression analysis of freshly isolated and flow-sorted primary human lung epithelial cells. a Expression levels of AT1 and AT2 differentiation markers in freshly isolated human lung epithelial cells (n = 12) b Expression levels of Wnt ligands and Fzd receptors in freshly isolated lung epithelial cells (n = 12). Mann-Whitney test * p < 0.05, ** p < 0.01, *** p < 0.001. (See also Additional file 1: Figure S1 and S2)Back to article page
