Figure Lengend Snippet: Figure 3. Finerenone reduced VEGF and vascular leakage in (mRen-2)27 after 12 weeks of diabetes. D, diabetic. Veh, vehicle. Per, perindopril. Fin, finerenone. (A) Three-micrometer paraffin sections of retina immunolabeled with VEGF and counterstained with hematoxylin. GCL, ganglion cell layer. IPL, inner plexiform layer. INL, inner nuclear layer. Scale bar = 40 µm. Ganglion cells denoted by single asterisk (*). Glial cells denoted by double asterisks (**). (B) Quantitation of VEGF immunolabeling in the retina. * p < 0.05 to diabetic+vehicle. n = 4 to 5 rats per group. (C) Vitreal levels of albumin (ELISA). * p < 0.05 to non-diabetic and diabetic+vehicle. # p < 0.05 to non-diabetic. n = 7 to 8 rats per group. Values are mean ± SEM.

Article Snippet: Immunohistochemistry for VEGF was performed by incubating three-micrometer paraffin sections with normal donkey serum for 1 h (D9663, Sigma-Aldrich), and then goat anti-rat VEGF (1:500, 564-RV, R&D Systems, Minneapolis, Minnesota, USA) overnight at 4 ◦C.

(A) Retinal wholemounts labeled with FITC-isolectin to delineate retinal blood vessels in green. Top panels show whole retina. A quadrant of retina (yellow box) is magnified in the lower panel. Scale bar = 500 µm. Asterisks denote vaso-obliteration. Arrows denote neovascularization. (B) Quantitation of retinal neovascularization. * p < 0.05 to OIR+vehicle. n = 5 to 7 mice per group from 2 to 3 liters per group. (C) Retinal VEGF protein levels (ELISA). (D) Retinal VEGF mRNA levels. (E) Retinal vascular leakage (albumin ELISA). ** p < 0.01, **** p < 0.0001 to RA. # p < 0.05, ### p < 0.001 to OIR + vehicle (Kruskal–Wallis test). n = 5 to 8 mice per group from 2 to 3 litters of mice per group. Values are mean ± SEM.

Article Title: Top2b regulates morphological and migratory properties of retinal progenitor cells in vivo and upon transplantable matrix substrates

doi: 10.37349/ebmx.2025.101335

Figure Lengend Snippet: Figure 6. Cultured retinal progenitor cell groups with Top2b overexpression (OE) and knockdown (KD) illustrate altered expression of select chemotactic receptors compared to wildtype cell groups with no Top2b manipulation (WT). Cell groups illustrated significant differences in the expression of selected chemotactic receptors: vascular endothelial growth factor receptor (VEGFR1), fibroblast growth factor receptor (FGFR1), and c-x-c chemokine receptor 4 (CXCR4, receptor for the stromal cell-derived factor 1, SDF-1a, ligand). Statistical significance across the cell groups is denoted by p-value: * < 0.05, ** < 0.01, **** < 0.0001 as via two-way ANOVA tests followed by Dunnett’s post-hoc test

Article Snippet: Approximately 600 μL of each growth factor vascular endothelial growth factor (VEGF; R&D Systems, Minneapolis, MN, USA, 564-RV), fibroblast growth factor-8 (FGF-8; Invitrogen, Carlsbad, CA, USA, PHG0184), and stromal derived factor 1-a (SDF-1a; Sigma Aldrich, St. Louis, MO, USA, SRP3276) was added to the bottom of separate transwell assays.

Techniques: Cell Culture, Over Expression, Knockdown, Expressing, Derivative Assay
