Figure 1. Growth initiation and morphological characteristics of limbal, oral, and conjunctival cultures. A: Growth initiation from the three explant cultures is shown. B: Confluent cultures of limbal, oral, and conjunctival cells are shown. C: Hematoxylin and eosin staining of sections of limbal, oral, and conjunctival cultures are illustrated. D: PAS staining of the three explant cultures is also shown. The inset in conjunctival culture shows goblet cells detected in native conjunctival tissue.
