Coexpression of vimentin and glial fibrillary acidic protein in glial cells of the adult rat pineal gland.
In the present work, coexpression of vimentin (VIM) and glial fibrillary acidic protein (GFAP) is demonstrated in the glial cells of the adult rat pineal gland. Serial consecutive Epon semithin sections (0.5 microns thick) were alternately immunostained for VIM and GFAP. GFAP positive cells and processes were found in the proximal region of the pineal gland, near the pineal stalk. Most of these cells were also immunostained for VIM in adjacent semithin sections. The significance of the coexpression VIM-GFAP and the restricted location of GFAP positive cells is discussed in relation with the maturation of pineal glial cells.
