Figure 2. Photomicrographs of rat conjunctival epithelial cells (Cj-ECs) in culture. A, B: Cj-ECs stained intensely for pan-keratin, a marker of conjunctival epithelial cells. C, D: Histochemical reactivity of primary culture of Cj-ECs to AB/PAS. Goblet cells stained intensely with AB/PAS, indicating the presence of both neutral (pink) and acidic (blue) glycoconjugates associated with cells. Magnification: (A, C), 100×; (B, D), 400×.
