Figure 2From: Expression of canonical WNT/β-CATENIN signaling components in the developing human lungExpression of canonical WNT/β-CATENIN signaling ligands in the developing human lung. ( A- D) Morphogenesis of the early human lung development at 7 W, 12 W, 17 W and 21 W (W: Weeks of gestation). WNT2 ( E- H) and WNT7B ( I- L) expression was detected in the epithelium of human lungs at 7 W, 12 W, 17 W and 21 W. Scale bars = 100 μm in A- L.Back to article page
