Figure 3. Angiogenic factors expression in placenta.

Figure 3.

Panel A to E shows the angiogenic expression in the placenta using immunofluorescence staining of VEGF, PlGF, VEGFR-1, VEGFR-2, and HIF-1α, respectively, with its semiquantitative analysis; VEGF: vascular endothelial growth factor; PlGF: placental growth factor; VEGFR-1: vascular endothelial growth factor receptor-1; VEGFR-2: vascular endothelial growth factor receptor-2; HIF-1α: hypoxia-inducible factor-1α. The examination was conducted using a fluorescence microscope Olympus IX71 with 400x magnification. The immunofluorescence figures were captured using a mobile device, which could explain the absence of a scale bar.
