Adrenal gland – A weak to moderate PGP9.5 positivity can occur in cortical cells adjacent to the medulla.

Adrenal gland – Strong PGP9.5 immunostaining in all medullary cells.

Aorta media – PGP9.5 staining is seen in some fibres of the media of the aorta.

Appendix, mucosa

Appendix, muscular wall

Bone marrow

Breast

Bronchus, mucosa – In the bronchus mucosa, PGP9.5 immunostaining occurs in a fraction of cells. A “mosaic pattern” displaying a mixture of positive and negative cells is typically seen.

Cerebellum (molecular layer, Purkinje cell layer, granule cell layer) – Strong PGP9.5 positivity in all neuronal cells and in axons. Glia cells are negative.

Cerebellum (white matter)

Cerebrum, grey matter – Strong PGP9.5 positivity in all neuronal cells and in axons. Glia cells are negative.

Cerebrum, white matter

Colon descendens, mucosa

Colon descendens, muscular wall – Strong PGP9.5 immunostaining of nerve fibres and ganglions in the muscular wall.

Duodenum, Brunner gland

Duodenum, mucosa

Epididymis – In the epididymis, PGP9.5 immunostaining is seen in a small fraction of cells in distal tubuli and collecting ducts. The staining intensity is variable and sometimes a “mosaic pattern” is seen.

Esophagus, squamous epithelium

Fallopian tube, mucosa – In the fallopian tube, a moderate PGP9.5 immunostaining is seen in scattered epithelial cells.

Liver

Lung

Lymph node

Ovary, stroma – The ovarian stroma exhibits a moderate PGP9.5 immunostaining.

Pancreas – In the pancreas, a strong PGP9.5 immunostaining is seen in virtually all cells of islets of Langerhans. In addition small nerve fibres stain positive.

Parathyroid gland

Parotid gland – In the parotid gland, a strong PGP9.5 immunostaining is seen in small nerve fibres.

Pituitary gland, anterior lobe

Testis – In the testis, a strong PGP9.5 immunostaining is seen in spermatogonia. PGP9.5 staining decreases sharply in spermatocytes where it is only faint. A moderate PGP9.5 staining is seen in Leydig cells while Sertoli cells remain PGP9.5 negative.

Thymus – Scattered PGP9.5 positive cells occur in the thymus.

Thyroid gland

Tonsil – Weak PGP9.5 immunostaining is seen in a fraction of lymphocytes in the tonsil.

Tonsil, surface epithelium – Staining of the epithelium surface represents ink (no true immunostaining).
