| Abstract: | The localization of fibronectin was demonstrated in the rat anterior pituitary by the highly sensitive double bridge peroxidase-antiperoxidase (PAP) method. The fibronectin immunopositive cells were characterized by stellate-like morphology. The cells immunostained for fibronectin were observed to be identical to those for S-100 protein in adjacent mirror sections, whereas the S-100 protein has been specifically immunodetected in the folliculo-stellate (FS) cells of the anterior pituitary. The present study indicates that the fibronectin is present in the FS cells, suggesting that FS cells might play a role in the regulation of pituitary function through the interaction of fibronectin with hormone secreting cells. |
