Fig. 2From: Progesterone distribution in the trigeminal system and its role to modulate sensory neurotransmission: influence of sexProgesterone receptor immunoreactivity in TG. PR immunoreactivity was localized in neuronal nucleus (thin arrows) and in cytoplasm (thick arrows). In addition, PR immunoreactivity was seen in the cytoplasm of satellite glial cells (arrowheads). There was observed a very weak expression of PR in the Schwann cells (asterisk). Blue colors represent nucleus staining with DAPIBack to article page
