Stability of SLATEs exposed to collagenase. A) Representative phase-contrast micrographs of A- and R-SLATEs immediately after self-release (T₀) and after collagenase treatment at different time intervals, up to 48 h (T₃–T₄₈). Human corneal stromal slices (Human cornea) and plastic-compressed high-density collagen gels were used as control matrices. Scale bar, 100 μm. B) Quantification of tissue degradation over time was evaluated from average ± S.D. percentage of weight loss of three individual samples, from three independent experiments (n = 3).
