Confocal examination of tight junction and MUC4 expression of the corneal epithelium in the CEC mice. Mice treated with fractions of ADSC-CM with molecular size < 10 kD or < 3kD showed better expression of (A) ZO-1 and K12, (B) ZO-1 and occludin, and (C) MUC4 than those treated with fractions > 10 kD or > 3 kD. (N = 3).
