Photomicrographs were taken at x400 final magnification. CK-15 N-cadherin Merge A B C epithelium stroma Supplementary Figure 2. Co-localization of CK-15 and N-cadherin to LESC clusters. Double immunofluorescence was conducted on sections of adult human corneas to co-localize CK-15 (A, green) with N-cadherin (B, red). Sections were counterstained with DAPI and images triple merged (C). Arrows identify CK-15+/N-cadherin+ basal limbal epithelial cells. Photomicrographs were taken at x400 final magnification.
