Reviewed milestones, validation shifts, standards, datasets, and debates linked to public evidence.
Evidence from Transplantation indicates that Pig-to-human xenotransplantation has had limited success, with one patient surviving over 72 hours in 1923. This is tracked as a clinical because it changes how Xenotransplantation is understood, validated, or applied.
Evidence from Transplantation indicates that Pig peripheral blood progenitor cell transplantation (PCTx) alone causes a thrombotic thrombocytopenic (TTP)-like microangiopathic state. This is tracked as a commercial because it changes how Xenotransplantation is understood, validated, or applied.
Evidence from Transplantation indicates that Successfully generated transgenic mice and pigs expressing human CD46. This is tracked as a breakthrough because it changes how Xenotransplantation is understood, validated, or applied.
Evidence from Xenotransplantation indicates that Pig-to-non-human primate model is the standard for in vivo xenotransplantation studies. This is tracked as a standard because it changes how Xenotransplantation is understood, validated, or applied.
Evidence from Xenotransplantation indicates that Low pre-formed anti-pig antibody titers are crucial for xenograft survival. This is tracked as a clinical because it changes how Xenotransplantation is understood, validated, or applied.
Evidence from Xenotransplantation indicates that Xenotransplantation carries a risk of transmitting porcine microorganisms, primarily viruses, to recipients. This is tracked as a clinical because it changes how Xenotransplantation is understood, validated, or applied.
Evidence from New England Journal of Medicine indicates that Successful xenograft function and weaning from ECMO. This is tracked as a standard because it changes how Xenotransplantation is understood, validated, or applied.
Evidence from Scientific reports indicates that Significant differences in E3-angles were observed between porcine and baboon left ventricles. This is tracked as a clinical because it changes how Xenotransplantation is understood, validated, or applied. It is supported by 2 papers in the same timeline signal.
Evidence from Viruses indicates that Retroviral transmembrane envelope proteins possess immunosuppressive activity. This is tracked as a review because it changes how Xenotransplantation is understood, validated, or applied.
Evidence from Frontiers in Immunology indicates that Gene editing, particularly CRISPR-Cas9, has enabled significant progress in kidney and heart xenotransplantation in pig-to-nonhuman primate models. This is tracked as a clinical because it changes how Xenotransplantation is understood, validated, or applied. It is supported by 2 papers in the same timeline signal.
Evidence from New England Journal of Medicine indicates that Genetically modified pig kidneys functioned in human recipients for 54 hours. This is tracked as a method because it changes how Xenotransplantation is understood, validated, or applied.
Evidence from Xenotransplantation indicates that Xenograft rejection differs significantly from allograft rejection. This is tracked as a clinical because it changes how Xenotransplantation is understood, validated, or applied. It is supported by 2 papers in the same timeline signal.
