Survival of adult islet grafts from transgenic pigs with N‐acetylglucosaminyltransferase‐III (GnT‐III) in cynomolgus monkeys

Abstract:  Background:  Because of a severe shortage of human donor pancreases, pig islets are considered to be an attractive donor source. Our previous in vitro study revealed that adult pig islets have strong non‐Galα1‐3Galβ1‐4GlcNAc‐R (α‐Gal) antigenicity, including the Hanganutziu‐Deicher (H‐D) antigen, especially in N‐linked sugars. In this study, the issue of whether islets from N‐acetylglucosaminyltransferase‐III (GnT‐III) transgenic pigs can prolong their survival in cynomolgus monkeys was examined.
