STRUCTURAL, IMMUNOCYTOCHEMICAL AND ULTRASTRUCTURAL STUDY OF FOLLICULOSTELLATECELLS AND FOLLICULAR CAVITIES OF LAMB (<i>OVIS ARIES</i> L.)
Abstract
We have studied the structure and ultrastructure of adenohypophyseal folliculo-stellate cells of 6 males and 6 females of sheep belonging to the Segureña breed, aged 3 months and weigthing 24 kg. Immunocytochemical technique (ABC) with serum against bovine S-100 protein bovine serum and electron microscopy were utilized. Folliculo-stellate cells are evenly distributed through the whole gland, making up 20-30% of all cells. These cells are specifically labelled with S-100 anti-protein bovine serum. These cells lack secretory granules and show few organelles. When they form cavities show a large amount of agranular endoplasmic reticulum, microvilli narrow and with scarce content or without it at all.Downloads
