CCN3 co‐localized with CA4 in mouse taste bud cells of CvP and FuP. Double‐labeled immunostaining for CA4 and CCN3 in CvP and FuP of a WT mouse (A) and a Ccn3‐KO mouse (B). Double‐labeled immunostaining for GNAT3 and CCN3 in CvP and FuP of a WT mouse (C) and a Ccn3‐KO mouse (D). Double‐labeled immunostaining for ENTPD2 and CCN3 in CvP of a WT mouse (E) and a Ccn3‐KO mouse (F). Scale bar, 20 μm. (G) Venn diagrams illustrating the overlap of CCN3 (red) and CA4 (green) immunoreactivity in CvP (a) and FuP (c), and the overlap of CCN3 (red) and GNAT3 (green) immunoreactivity in CvP (b) and FuP (d) in WT mice. Double‐labeled cells are shown in yellow. Cell counts are demonstrated in Table 1. WT mice (n = 7) and Ccn3‐KO mice (n = 8).
