Genetic modification of the source pig offers the opportunity to improve the engraftment and survival of islet xenografts. The type of modification can be tailored to the transplant setting; for example, intraportal islet xenografts have been shown to benefit from the expression of anticoagulant and anti-inflammatory transgenes, whereas cytoprotective transgenes are probably more relevant for encapsulated islets. The rapid development of pig genetic engineering, particularly with the introduction of genome editing techniques such as CRISPR-Cas, has accelerated the generation of new pig lines with multiple modifications. With pre-clinical testing in progress, it is an opportune time to consid..
