[The formation of psammoma bodies in the choroid plexus of the human brain].
Formation of psammoma bodies (PB) in choroid plexus of human telencephalon was studied using histochemical and immunocytochemical methods. PB formation was found to start during childhood. In early stages of development PB are not calcified and are formed by fibroblasts possessing a series of cytological diversities from the fibroblasts of the surrounding connective tissue. Cytoplasm of PB forming fibroblasts contains greater amount of vimentin. A suggestion is made on existence of special population of fibroblasts with an ability to form PB in connective tissue.
