Representative gross histology for granulocytes with H&E staining and T cells with anti-CD3 staining in autologous (A and B), non-decellularized guinea pig (C and D), decellularized guinea pig (E and F) and recellularized guinea pig (G and H) explanted tissues. Arrows highlight cells of interest, either granulocytes (A, C, E and G) or T cells (B, D, F and H). A red star in (G) highlights the lack of granulocyte infiltration in the recellularized guinea pig tissue.
