Testicle. (a) Foetuses: no immunoreactivity for Tβ4 is observed in the immature spermatic ducts (arrow). A mild cytoplasmic immunoreactivity of the peptide is observed in isolated interstitial cells (arrowhead). Scale bar: 25 µm. (b) Adults: a granular cytoplasmic immunoreactivity of Tβ4 is detected in the interstitial cells of the testicle (arrow). A weak immunoreactivity is observed in the cells of the spermatic ducts (arrowhead). Scale bar: 50 µm Inset: cells of the spermatic ducts with a weak immunoreactivity (arrows). Scale bar: 25 µm.
