Angiopoietins contribute to lung development by regulating pulmonary vascular network formation.

Angiopoietin (Ang) signaling through the Tie2 receptor regulates vasculature. The role of Ang signaling in pulmonary hypertension is well investigated, but its role in lung development is not elucidated. Here, we show that the Tie2 agonist ligand, Ang1, was detected in lung tissue at birth and its expression gradually increased in mice, whereas its… CONTINUE READING
