Fig. 6From: Liquid plasma promotes angiogenesis through upregulation of endothelial nitric oxide synthase-induced extracellular matrix metabolism: potential applications of liquid plasma for vascular injuriesLP induces endothelial cell migration and angiogenesis in vivo. Analysis of the survival rates. No statistically significant difference was observed in the survival rate between the LP-treated group, the non-treated group (N = 10, each group), and the vascular endothelial growth factor (VEGF)-treated group (positive control). B The Matrigel plug assay. Representative photomicrographs showing angiogenesis in response to the injected Matrigel. Capillary formation towards the Matrigel was thickened in the LP-treated group compared to that in the control group; scale bar = 20 μm. (C) H and E staining of Matrigel plug sections from control and LP-treated mice; scale Bar = 200 μm. D Image shows the morphology of Matrigel plugs harvested from LP-treated and control mice; scale bar = 20 mm. E Hemoglobin content is shown in graphs (N = 10 per group). Data are presented as mean ± SEM. **P < 0.01, **P < 0.01, and ***P < 0.001 Student t test. F, G Immunofluorescence analysis of endothelial cell marker CD31 (red) and NO signaling pathway marker p-eNOS. p-AMPK levels in the sections of the Matrigel plugs derived from control and LP-treated mice are shownl nuclei are labeled using DAPI (blue); scale bar = 100 μm. Quantification of CD31-positive cells (10 fields/group), p-eNOS(S1177), p-AMPK (Thr172). ***P < 0.001Back to article page
