Description	Virtually all Schwann cells and ganglionic satellite cells of peripheral nerves must show a moderate to strong, cytoplasmic and nuclear staining reaction.	The vast majority of adipocytes must show an at least weak to moderate nuclear and cytoplasmic staining reaction.	No staining reaction in epithelial cells in the epithelial mucosa.
