Fig. 3From: Isoprenaline/β2-AR activates Plexin-A1/VEGFR2 signals via VEGF secretion in gastric cancer cells to promote tumor angiogenesisPlexin-A1 expression is co-localized with VEGFR2 in gastric cancer cells. Representative images of immunohistochemical fluorescent double staining of plexin-A1 (in red color, left column) and VEGFR2 (in green color, middle column) in gastric cancer; co-localization is shown in the right column (arrows).
