From: Characterisation and localisation of the endocannabinoid system components in the adult human testis
Immunohistochemical expression of the endocannabinoid-synthesising enzymes, NAPE-PLD and DAGLA, in the adult human testis. The images on the left show a general expression pattern, and a higher magnification of an area within a stippled line is shown on the right. All pictures show a low magnification image of negative controls in the right upper corner. NAPE-PLD was present in Leydig and Sertoli cells. DAGLA was present predominantly in the nuclei of germ cells, with only weak reaction detected in Sertoli and Leydig cells. L (leptotene) and P (pachytene) indicate early and late spermatocytes, respectively.
