Fig 1: Expression of corneal stromal ECM markers at the protein level. A- and R-SLATEs were imaged by immunofluorescence confocal microscopy and detection of A) collagen-I and keratocan, B) collagen-V and lumican, C) ALDH1 and decorin, D) CHST6 and aSMA, or E) ALDH3 and fibronectin was analyzed by tridimensional reconstruction of a 300 × 300 µm area from tissues. Cell nuclei were identified by DAPI staining. Signal specificity was evaluated using F) secondary antibody-only controls.
