Fig. 5From: The alveolar epithelial cells are involved in pulmonary vascular remodeling and constriction of hypoxic pulmonary hypertensionEffects of AECs conditioned culture medium on the constriction of PA ring. A ATII hypoxic hypoxic culture medium significantly promoted the constriction of PA ring from normoxic rats (a–c) the representative curve for the effect of culture medium, ATII normoxic and hypoxic culture medium on the constriction of PA ring from normoxic rats (d) the summarized data of PA ring maximum constriction. B ATII hypoxic culture medium significantly promoted the constriction of PA ring from HPH rats (a–c) the representative curve for the effect of culture medium, ATII normoxic and hypoxic culture medium on the constriction of PA ring from HPH rats (d) the summarized data of PA ring maximum constriction.
