(A) Two-dimensional contrast echocardiogram showing pulmonary arteriovenous malformations. (B) Protein abundance of angiopoietin-1, angiostatin, TEK (Tie-2), endoglin, Kruppel-like factor (KLF-2), and vascular endothelial growth factor (VEGF) in the right lung of superior cavopulmonary connection (SCPC) pigs expressed as a fold change from values obtained in the left lung of the SCPC pigs and controls (set to 100% [dashed vertical line]). (∗p < 0.05 versus right lung; #versus left lung SCPC; SVC = superior vena cava.)

3. Fig 2
(A) Proliferation of smooth muscle cells from the left pulmonary artery (LPA), right pulmonary artery (RPA), and controls expressed as a change from the 24-hour time point (set to zero). There were no differences between the LPA and the RPA. (B) Proliferation of RPA endothelial cells was higher than the LPA and controls (∗p < 0.05 versus LPA; #p < 0.05 versus time 0). (C) Photomicrographs of endothelial cells from the LPA and RPA pig at 5 days after plating. (D) Photomicrographs of endothelial cells from the LPA and RPA at similar confluence. (Photomicrographs were recorded using a 20× Nomarski differential contrast objective.)

(A) Immunoblots for endoglin, Kruppel-like factor (KLF-2), TEK (Tie-2), and β-actin in lysates of endothelial cells from the left pulmonary artery (LPA), right pulmonary artery (RPA), and control. (C) The KLF-2 abundance was statistically similar between LPA, RPA and controls; the (B) endoglin and (D) Tie-2 abundance was higher in the RPA than in the LPA (∗p < 0.05 versus LPA).

5. Fig 4
Radar plot showing relative gene expression profiles for genes related to extracellular matrix (ECM) degradation, ECM deposition, and cellular signaling. The plot for the left pulmonary artery (LPA [plane defined by the red triangle]) and control (plane defined by the green triangle) was clearly different than the plane defined for the right pulmonary artery (RPA [blue triangle]). Fold expression levels for the genes that resulted in this plot are summarized in Appendix Table 1.

6. Fig 5
(A) Photomicrographs of endothelial cells from the left pulmonary artery (LPA), right pulmonary artery (RPA), and controls 3 hours after plating. Cells from the LPA (left) and controls assembled into a number of nodes and tubule extension had commenced as evidenced by thin structures between nodes. In contrast, cells from the RPA—at the same timepoint—had assembled into a well-defined network structure between nodes, consistent with a more proangiogenic phenotype. (Photomicrographs were recorded using a 2.5× objective with phase contrast. Scale bars: 100 μm.) (B) Number of tubes and (C) total length of tubes were higher in the RPA than in the LPA (∗p < 0.05 versus LPA).
