Cell Proliferation Induced by PDGF‑AA and Neutralization by Mouse PDGF R alpha Antibody.

Recombinant Human PDGF-AA (221-AA) stimulates proliferation in the NR6R-3T3 mouse fibroblast cell line in a dose-dependent manner (orange line), as measured by Resazurin (AR002. Proliferation elicited by Recombinant Human PDGF-AA (250 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse PDGF Ra Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1062). The ND₅₀ is typically 0.2-1.6 µg/mL.

(h–k) IF labeling of brain tumor sections for cell type specific markers. Nuclei labeled with DAPI are shown in blue. Tumor cells with high PDGFR alpha expression were highly proliferative, as seen by proliferation marker Ki67 (h), and express the OPC cell lineage markers Olig2, Sox2, Sox10, and Ng2, as well as the neural stem cell marker Nestin (i–k). Tumor cells were negative for immunosignal of astroglial marker GFAP, mature oligodendrocyte marker APC-CC1, and neuronal marker NeuN (l–n). Scale bars: 10 μm (a–g), 20 μm (h–n).

PDGFR alpha and ciliary axonemes early in development. (A) High-resolution microscopy and (B,C) 3D IHC reconstructions of 15 µm wildtype tissue show phosphorylated PDGFR alpha (red) present along ciliary axonemes (acetylated tubulin, green) (arrowheads highlighted in C) at E13. By P0, the receptor localizes to the endocardium where cilia are absent (arrows).

Impact of LPC surgery on mice subjected to running wheel. (A) Workflow and representative eriochrome cyanine-stained sections with lesion in the ventrolateral white matter delineated by dashed lines. Figure was drawn using BioRender. (B) Representative images of LPC lesion (left) and contralateral normal appearing white matter (right) 4 days post injury stained for mature oligodendrocytes (CC1) in red, OPCs (PDGFR alpha) in green, oligodendrocyte lineage cells (OLIG2) in white, and DNA (DAPI) in blue. (C) Representative images of LPC lesion 4 days post injury stained for myelin and myelin debris (MBP) in red, axons (NFH) in green, and astrocytes (GFAP) in white, and DNA (DAPI) in blue. In both (B) and (C), the lesion is outlined by the irregular dashed line while the non-involved contralateral site is denoted by the rectangle dashed line. Scale bar represents 100 μm.

Reduced number of MSCs at the periodontitis site in aged mice. Immunofluorescence images show the number of platelet-derived growth factor receptor alpha (PDGFR alpha)+ MSCs (red) in the furcation area in young and aged mice. Cell nuclei were stained with DAPI (blue). Bar: 100 µm. The graph shows the quantitative analysis indicating that the number of PDGFR alpha+ Mesenchymal stem cells (MSCs) is decreased in aged mice, more prominently at day-10 after ligation. The bar graph represents the mean ± standard deviation of at least three independent samples. * p < 0.05, ** p < 0.01, *** p < 0.001, two-way ANOVA, Tukey test (n = 3).
