1 Thymus - Epithelial Reticular CellsThis image from the medulla shows many epithelial reticular cells, which have a pale cytoplasm, large nucleus, and prominent nucleolus. These cells form a meshwork which contains developing lymphocytes. One macrophage or PAS cell is visible. PAS stains its phagocytic inclusions bright pink. Note the...epithelial reticular; Hassall's corpuscle; PASUCLA Histology
2 Thymus - MedullaIn this image of the medulla, identify lymphocytes, PAS cells, and an epithelial reticular cell. UCLA Histology Collection.medulla; PASUCLA Histology
3 ThyroidA low magnification of the thyroid gland stained with PAS. The fact that the colloid is PAS+ indicates that the colloid (thyroglobulin) is a glycoprotein. UCLA Histology Collection.PAS; ThyroidUCLA Histology

5 Cells / Organelles - HepatocytesPAS stains cytoplasmic glycogen granules pink. Identify the nucleus and the nucleolus of a hepatocyte. UCLA Histology Collection.PASUCLA Histology
6 ThyroidA higher magnification of the PAS stained thyroid gland. Again, the follicles are filled with PAS positive colloid or thyroglobulin, a glycoprotein which is the stored form of thyroid hormone. Shrinkage artifacts are present within the colloid but not within the epithelial cells. The arrow indicates...PAS; ThyroidUCLA Histology
