Gözden geçirmenin amacı: Bu çalışmanın amacı, ksenotransplantasyondaki son ilerlemeyi vurgulamak ve sağlık sisteminin bir klinik deneyi onaylaması olası hale gelmeden önce kalan engelleri/adımları tartışmaktır.
Bulgular: Klinik öncesi modellerde yaşamı destekleyen ksenogreftlerin uzun süreli hayatta kalması, ksenotransplantasyonun klinik deneylerinin tartışılmasına yol açmıştır. FDA onayına dayalı klinik kardiyak ksenotransplant raporları ve beyin ölümü gerçekleşmiş insanlara renal ksenotransplantlar, klinik denemelerin daha fazla değerlendirilmesine yol açmıştır. Transplant topluluğu ve bilim kurulları arasındaki tartışmalar, ksenotransplantların klinik bir denemesinin onaylanmasından önce kritik sonraki adımları belirledi. Bu adımlar, klinik bağışıklık bastırma protokolünün ve genetiği değiştirilmiş bir kaynak hayvandan alınan organın, en az 6 aylık tekrarlanabilir hayatta kalma süresine sahip insan olmayan primatlarda test edilmesini içerir. Ek olarak, uygun viral sürveyans protokolleri ve ksenogreftlerin uygun insan fizyolojisini desteklediğine dair onay, muhtemelen sağlık örgütü onayı için kritik unsurlar olacaktır. Son olarak, insan ölü modelinde yapılacak daha ileri çalışmaların, ksenogreftlere karşı insan immün ve fizyolojik tepkileri hakkında kritik bilgiler sağlaması muhtemeldir.

Sonuç: Bu gözden geçirme, insan dışı hayvan modellerindeki mevcut ilerlemeyi ve insan ksenotransplantasyonuna ilişkin son çalışmaları vurgulamaktadır. Ayrıca, klinik bir ksenotransplantasyon denemesi onaylanmadan önce ulaşılması gereken kalan engelleri ve şu anda anlaşılan klinik gerekliliklerini gerekliliklerini de açıklamaktadır.
