Use of decellularized pig lung scaffolds recellularized with human lung cells in xenogeneic transplantation is potentially limited by expression of immunogenic galactosylated cell surface glycoproteins. Use of alpha 1,3 galactosyltransferase knock out (α-gal KO) pigs presents a potential alternative. Comparison of decellularized wild type (WT) vs α-gal KO pig lungs by histologic, immunohistochemical, and mass spectrometric techniques demonstrated no obvious differences in histologic structure was observed but an approximate 25% difference in retention of residual proteins including retention of α-galactosylated epitopes in WT lungs. Comparable robust initial recellularization and subsequent growth and proliferation was observed in wild type (WT) vs α-gal KO pig lungs following compartmental inoculation of human lung bronchial epithelial cells (HBE), human lung fibroblasts (HLF), and human bone marrow-derived mesenchymal stromal cells (MSCS) and of human pulmonary vascular endothelial cells (CBF). These initial sutides support further investigation of decellularized α-Gal KO pig lungs for xenogeneic lung regeneration.
