Xenotransplantation Using Lyophilized Acellular Porcine Cornea with Cells Grown in vivo and Stimulated with Substance-P - Biomaterials Science and Engineering - page 392

Fig. 2. Hematoxylin-eosin staining of amniotic membranes (A, B), lyophilized acellular
porcine corneas (C, D), and collagen sheets (E, F) (B, D, F soaked in substance-P).
Amniotic membranes and lyophilized acellular porcine corneas had more keratocytes (black
arrow) than collagen sheets. Lyophilized acellular porcine corneas were shown to have less
inflammatory cells (black arrowhead) than amniotic membranes and collagen sheets.
Keratocytes were more visible in implants treated with substance-P. Original magnification:
