Figure 3From: Expression of canonical WNT/β-CATENIN signaling components in the developing human lungExpression of canonical WNT/β-CATENIN signaling receptors in the developing human lung. The expression of canonical WNT signaling receptors, including FZD4 ( A- D), FZD7 ( E- H), LRP5 ( I- L) and LRP6 ( M- P), was clearly detected in the distal part of human lung epithelium at 7 W, 12 W, 17 W and 21 W (W: Weeks of gestation). Scale bars = 100 μm in A- P.Back to article page
