Figure 4. Co-expression of GHSR and taste cell markers in circumvallate papillae (CV) of mice.
(A) GHSR and NTPDase2 are co-localized in a subset of NTPDase2-positive cells (arrow). (B) GHSR and PLCβ2 are co-localized in a subset of PLCβ2-positive cells (arrow). (C) GHSR and α-gustducin are co-localized in a subset of α-gustducin-positive cells. Arrow, cells expressing both. (D) GHSR and NCAM are co-localized in a subset of NCAM-positive cells. Arrow, cell expressing both. (E) GHSR and PGP9.5 are co-localized in a subset of PGP9.5-positive cells (arrow). (F) GHSR and Shh are co-localized in a subset of Shh-positive cells (arrows). (G) GHSR and PLCβ2 are stained in ghrelin null mice as a negative control. (H) GHSR and PLCβ2 are co-stained after the ghrelin antibody was omitted. Scale bars, 20 µm. Blue is TO-PRO-3 nuclear stain.
