FIG. 4.

Normal human ocular mucosal tissues labeled with anti-gp340. (a) Normal human conjunctiva. Immunostaining with anti-gp340 shows localization in the basal layers of the conjunctiva and in isolated cells within the underlying loose connective tissue. The brace delineates the conjunctival epithelium, and the arrowheads indicate unlabeled goblet cells. (b) Normal human lacrimal gland. Immunostaining with anti-gp340 shows localization acini (circle), but not in connective tissue (*). (c) gp340-positive basal cells in the peripheral cornea (arrow). (d) Labeled cells are absent from the central cornea. Bar = 100 μM.
