Expert opinion on the identification, risk assessment, and mitigation of microorganisms and parasites relevant to xenotransplantation products from pigs

Xenotransplantation, Volume 30, Issue 5, September/October 2023., 2023
Abstract Xenotransplantation has the potential to address shortages of organs available for clinical transplantation, but concerns exist regarding potential risks posed by porcine microorganisms and parasites (MP) to the health of human recipients. In this study, a risk‐based framework was developed, and expert opinion was elicited to evaluate porcine ...
