초록 | To overcome the hyperacute immune rejection during pig-to-non-human primates xenotranasplantation, we have produced and bred ${ alpha}$ -1,3-galactosyltransferase knock-out ( $GalT^{-/-}$ ) pigs. In this study, the somatic cells and tissues from the $GalT^{-/-}$ pigs were characterized by an analysis of the expression of Gal ${ alpha}$ -1,3-Gal ( ${ alpha}-Gal$ ) epitope. Briefly, ear fibroblast cell lines of 19 homozygous $GalT^{-/-}$ pigs were established and cryopreserved. The expression of ${ alpha}-Gal$ epitope in the cells was measured by fluorescence activated cell sorter (FACS) analysis using BS-I-B4 lectin. Also, the homozygous ( $GalT^{-/-}$ ) cells and tissues samples were immunostained with BS-I-B4 lectin for analysis of ${ alpha}-Gal$ epitope expression. The results showed that the expression of ${ alpha}-Gal$ epitope in $GalT^{-/-}$ cells (0.2 %) were significantly (p $GalT^{-/+}$ ) (9.3 %) and wild type ( $GalT^{+/+}$ ) (93.7 %) fibroblast cells. In the immunostaining results, while the expression of ${ alpha}-Gal$ epitope was detected a partly in $GalT^{-/+}$ cells and mostly in $GalT^{+/+}$ cells, it was almost not detected in the $GalT^{-/-}$ cells. Also, immunostaining results from various tissues of the $GalT^{-/-}$ pig showed that the expression of ${ alpha}-Gal$ epitope was not detectable, whereas various tissues from $GalT^{+/+}$ pig showed a strong expression of ${ alpha}-Gal$ epitope. Our results demonstrated that ${ alpha}-Gal$ epitope expressions from $GalT^{-/-}$ pigs were successfully knocked out to prevent hyperacute immune rejection for further study of xenotransplantation. |
