Figure 1 A, Immunohistochemistry examination of hHGF in lung tissues (n = 120 slices per group). A-a, C group. A-b, E group. A-c, H group. A-d, Magnification of A-c. A-e, hHGF expression in the bronchial epithelium. In contrast to the C and E groups, positive signals were observed in the cytoplasm of VECs and epithelial cells in lung tissues of the H group. Bar = 100 μm. B, Semiquantitative analysis of the hHGF immunohistochemistry examination. a, C group. b, E group. c, H group. *P < .05 versus C group. #P < .05 versus E group. C, Western blot showed that no specific band in the C and E groups (n = 12 per group) and the band in the H group (n = 12) were proved to be the hHGF after gene transfection. D, Relative intensity of hHGF in the 3 groups. a, C group. b, E group. c, H group.*P < .05 versus C group. #P < .05 versus E group. GAPDH, Glyceraldehyde phosphate dehydrogenase; hHGF, human hepatocyte growth factor.

Figure 3 VIII factor antibody was labeled with fluorescein isothiocyanate (green), and α-smooth muscle actin antibody was labeled with rhodamine (red). Arrows indicate the partial muscular arteries. A1-A3, C group. B1-B3, E group. C1-C3, H group. Bar = 100 μm. The partial muscular vessel density was analyzed (n = 120 per group). A, C group. B, E group.
