Mouse Epiregulin Antibody

Cell Proliferation Induced by Epiregulin and Neutralization by Mouse Epiregulin Antibody.

Recombinant Mouse Epiregulin (Catalog # 1068-EP) stimulates proliferation in the Balb/3T3 mouse embryonic fibroblast cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Mouse Epiregulin (3 ng/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Mouse Epiregulin Monoclonal Antibody (Catalog # MAB1068). The ND₅₀ is typically 0.2-1 µg/mL.

EREG acts as a potential factor for vaginal epithelial cell proliferation and differentiation. A Heatmap of the expression levels of ErbB signaling pathway signature genes in the vagina of control and Rptor cKO mice in the presence or absence of E2 administration. B qPCR was performed to verify the genes in the frame in A. n = 7 (OVX control mice), n = 5 (OVX Rptor cKO mice), n = 6 (OVX control mice treated with E2), n = 5 (OVX Rptor cKO mice treated with E2). Values are expressed as the mean ± SEM. C Representative images of the immunofluorescence staining of EREG in the vagina in OVX control and Rptor cKO mice administrated with or without E2. Nuclei were stained with DAPI. Microscopy with magnification ×20. Scale bars: 75 μm. D OVX control and Rptor cKO mice were administrated with E2 and/or EREG. The vaginas were harvested for PAS staining, Ki67 immunofluorescence staining, and TUNEL staining. In PAS staining, nuclei were stained with hematoxylin. Scale bars: 50 μm. In Ki67 immunofluorescence staining and TUNEL staining, nuclei were stained with DAPI. Microscopy with magnification ×20. Scale bars: 75 μm. E Expression levels of Krt6a, Krt6b, Krt10, Krt13, Krt16 in the vagina of the mice were quantified using qPCR. n = 6 (OVX control mice treated with E2), n = 5 (OVX Rptor cKO mice treated with E2), n = 4 (OVX Rptor cKO mice treated with E2 and EREG). Values are expressed as the mean ± SEM. F The vaginas as indicated in D were harvested for immunofluorescence staining of YAP1, nuclei were stained with DAPI. n = 6 (OVX control mice treated with E2), n = 5 (OVX Rptor cKO mice treated with E2), n = 4 (OVX Rptor cKO mice treated with E2 and EREG). The experiments were repeated three times. Microscopy with magnification ×20. Scale bars: 75 μm.
