Summary of α-SMA Expression in Normal hLF and dFib RAFT TEs

	Non-AL, hLE−	Non-AL, hLE+	AL, hLE−	AL, hLE+
Normal hLF	−	−	−	−
dFib	+++	+	+++	+

− indicates 0–1 α-SMA positive cells out of 10.

+ indicates 2–4 α-SMA positive cells out of 10.

+++ indicates 8 or more α-SMA positive cells out of 10.

This scoring system is described in the Materials and Methods section.

AL, airlifted; α-SMA, α-smooth muscle actin; dFib, human conjunctival fibroblasts isolated from donors with ocular mucous membrane pemphigoid; hLE, human limbal epithelial cells; hLF, human limbal fibroblasts; RAFT, real architecture for 3D tissue; TEs, tissue equivalents.
