Figure 3. Representative photographs and H-E stained sections of the porcine corneas decellularized by various methods. The left column shows photograph of native cornea (A), cornea treated with Triton® X-100 (C), cornea treated with SDS (E) and cornea decellularized by UHP (G). The right column shows H&E stained section of native cornea (B), cornea treated with Triton® X-100 (D), cornea treated with SDS (F) and cornea decellularized by UHP (H). Epithelial cells and keratocytes are seen in the corneas treated with Triton® X-100 or SDS but not in the cornea treated with UHP. Scale bar, 50 µm.
