Fig. 6. Co-localization of PTX3 and HA in ovulated cumuli.
Ptx3+/ cumuli were stained for HA (red), PTX3
(green) and chromatin (blue), as reported in Materials and methods, and the
innermost (A-D) and outermost (E-H) layers of a cumulus were photographed
using a fluorescence microscope. HA histochemical staining (A,E); PTX3
immunostaining (B,F); merging of the two signals (C,G); and staining of
cumulus cell nuclei (D,H). Cumuli incubated with secondary probes only showed
no specific staining (data not shown).
