Immunohistological analysis of decellularized corneas.
Native (a) and decellularized cornea (b) were immunostained with anti-type I collagen antibody. Representative images of type I collagen immunostaining of decellularized corneas at postoperative 2 weeks (c) and 8 weeks (d). Brown-stained areas indicate the transplanted decellularized corneas. Scale bars: 200 μm in (a,b); 250 μm in (c,d).
