PAX3 expression in conjunctival and organ-cultured corneoscleral tissues. (A) Double immunostaining of conjunctival tissue sections showing PAX3+ cells (arrows) at the basal layer of conjunctival epithelium. These cells do not express PAX6, cytokeratin 13 (CK13), or CK15 (red) but do express vimentin (arrow, red) and melanocyte markers Melan-A (red) and SOX10. The dashed line represents the basement membrane. (B) Double immunostaining of organ-cultured corneoscleral tissue demonstrating PAX3+ cells (arrows) expressing Melan-A (red). Nuclear counterstaining with DAPI (blue).
