Xenogeneous antigens reduction of DLSs.

(A) The PCR semi-quantification for porcine endogenous retrovirus (PERV), PERV polymerase (PERV Poly), swine leukocyte antigen DR alpha (SLA-DRA), swine leukocyte antigen 2 (SLA-2), sus scrofa cytochrome b (SsCytb) and porcine beta actin (β-actin) in the DLSs. All the DNA sequences encoding potentially pathogenic or immunogenic antigens were not detected after decellularization process. (B) Immunohistochemistry staining of normal liver tissue and DLSs for α-Gal. Scale bars, 100 μm.
