Thanks Lyn. You are a star. The second paper seems to be the most comprehensive/and qualified. The key paragraph.
”Initially, PSA expression was reported to be exclusive to the epithelial cells of the prostate gland, but later it was found that low levels of PSA are also present in other tissues and biologic fluids. PSA immunoreactivity has been detected in the mammary glands, salivary glands, pancreas, breast milk, thyroid gland, placenta, amniotic fluid and semen, as well as in various malignant tis- sues. By RT-PCR, PSA encoding transcripts have been de tected in the endometrium, trachea, thyroid gland, salivary gland, pancreas, placenta and uterus, and low levels have also been detected in the pituitary gland, testis and peripheral leuko- cytes. Some of the cited findings are contradictory and were in most cases obtained by the use of a single method. Extrapros- tatic expression of hK2 has not been studied extensively; never- theless low levels of immunoreactivity have been found in saliva, amniotic fluid, mammary gland and breast milk, and transcripts encoding hK2 have been observed in the prostate, thyroid gland, endometrium and pituitary gland.”
Cant see the Adrenal gland mentioned anywhere and the paper looks like it is discussing where PSA is secreted (e.g. Fluids) and where it comes from. But I will be asking more questions and refer to this at my next meeting.
