Summary of the cell types with positive staining for peptidergic and monoaninergic neuronal makers and their intensity
| Positive cell types |
|||
|---|---|---|---|
| Markers | Leydig cells | Spermatogonia | Myoid cells |
| PGP 9.5 | +++ | ++ | − |
| NPY | ++ | − | ++ |
| CPON | ++ | − | ++ |
| VIP | ++ | − | − |
| DBH | ++ | − | − |
| 5-HT | ++ | − | − |
The relative intensity of each neuronal marker in certain cell types is recorded using the following scoring system: −, no staining; +, weak staining; ++, moderate staining; +++, intense staining.
