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.

Figure Lengend Snippet: Figure 4. Induction of VEGF (A,B), angiogenic factors (C) or pro-inflammatory factors (D) in cultured cells in vitro. RAW264.7 cells, NIH3T3 cells or U937 cells were cultured in hypoxic condition (5% or 0.5%) for 8 h (A,C,D) or indicated time period (B). The induction of Vegf (A), angiogenic factors (C) or pro-inflammatory factors (D) was then examined by RT-PCR analyses (A,C,D, n = 6) and the secretion of VEGF by ELISA (B, n = 6). Data represents as Mean and S.E.M. Statistical analysis was done by a non-parametric Mann–Whitney test or by a Kruskal–Wallis test followed by a Steel test. *p < 0.05, **p < 0.01.

The images of immunofluorescent staining of IA lesions for VEGF (green), the marker for macrophages, CD68 (red), the marker for smooth muscle cell, α-smooth muscle actin (SMA, gray), nuclear staining by DAPI (blue), and merged images are shown. The images from immunohistochemistry without a primary antibody were served as a negative control. Magnified images corresponding to the square in the upper panels are shown in the lower panels. Scale bar: 50 μm.
