title: The presence of progesterone receptors in arachnoid granulations and in the lining of arachnoid cysts: its relevance to expression of progesterone receptors in meningiomas.
abstract: Progesterone receptors (PR) were identified with an enzyme immunoassay in cytosols from human arachnoid granulations and arachnoid cysts. Meningiomas presumably originate from subdural endothelium which is abundantly present in these structures. In the three cases studied, oestrogen receptors were absent. The presence of PR in subdural endothelium may provide further ground for the expression of PR in meningiomas.
