Xenotransplantation: Current Challenges and Emerging Solutions
A Brief History of Xenotransplantation. In the 17th century, the first reported case of xenotransplantation (and blood transfusion) to humans was conducted by Jean-Baptiste Denis who transfused the blood of a lamb into a 15-year-old male suffering from a fever 10.Denis subsequently continued to transfuse blood from lambs and calves but with variable outcomes, so the French and English ...

In this paper I will discuss some background on organ transplantation, notable instances of successful organ ... the corresponding objections and rebuttals, and close with policy proposals pertaining to my thesis. Background Xenotransplantation is not a new phenomenon; it is a continuation of past medical research. The earliest documented ...
Xenotransplantation: Past, Present, and Future
Past. The concept of xenotransplantation is not new, and there have been numerous clinical attempts during the past 300 years or more [].Clinical blood xenotransfusion was attempted in the 17 th century by Jean Baptiste Denis, corneal xenotransplantation from pig-to-human followed in the early 19 th century, and attempts were made at nonhuman primate (NHP) kidney xenotransplantation in the ...
Xenotransplantation: A New Era
Since the 1990s, utilization of donor xenografts from pigs has been the main focus of study. Xenotransplantation utilizing pig xenografts could provide a theoretically endless supply of alternative allografts ( 10 ); however, a number of barriers exist for the use of porcine xenografts in clinical practice.

Xenotransplantation provides its readership with rapid communication of new findings in the field of organ and tissue transplantation across species barriers, and investigates and reports on the controversial theological, ethical, legal and psychological implications of xenotransplantation. Part of the Transplant Peer Review Transfer network ...
Xenotransplantation: Current Status in Preclinical Research
Thanks to genetically modified pigs and immunosuppressive therapy, survival time results for xenografts have improved considerably in preclinical xenotransplantation models. These results in NHP models indicate that the use of xenotransplantation in clinical applications is approaching. In this article, we (a) describe our understanding of ...

Full article: Xenotransplantation
The transplantation of living cells, tissues or organs from one species to another is termed xenotransplantation. The history of xenotransplantation is as old as allogeneic transplantation itself. Early attempts were made at a time when the immunologic basis of organ rejection were poorly understood. The advent of potent immunosuppressive ...
Xenotransplantation: Advancing Medical Innovation Through Cross-Species
Addressing the critical issues of immunological rejection and the risk of viral infections is essential in xenotransplantation. Zhou et al. 5 provide an in-depth review of the viral infections associated with the procedure, highlighting the necessity for sensitive diagnostics and effective antiviral therapies. Meanwhile, Suh et al. 6 reveal that additional genetic modifications do not always ...
Frontiers
Figure 1 Mechanisms of rejections during xenotransplantation.(A) Hyperacute rejection occurs within minutes to hours and is caused by the binding of the host's pre-existing antibodies to α-Gal antigens on the graft, which results in complement activation and membrane attacking complex (MAC) formation. This reaction causes endothelial cells lysis, fibrinoid occlusion, and vasculature ...

Xenotransplantation: Current Challenges and Emerging Solutions
The improved life expectancy of humans over the past decades has increased the prevalence of a growing number of chronic diseases 1.The increasing application of organ transplantation, the last resort and definitive treatment for end-stage organ failure, has resulted in a disparity in the supply and demand for such organs 1.Therefore, xenotransplantation has become an appealing solution to ...

Expert consensus on clinical trials of human xenotransplantation in
The history of xenotransplantation started from the experiments of skin grafts and corneal transplantation in the 19th century, while the development of solid organ transplantation from animals to humans was not seen until the 1960s [].The experiments of kidney, heart, and liver xenotransplantation were attempted without lasting success [].After a few decades of investigation, significant ...
Ethical and Societal Issues Occasioned by Xenotransplantation
Xenotransplantation animals will be kept under deprived laboratory conditions that similarly fail to meet the animals' natures. This is a significant concern for society in general. There are also issues of "bad ethics" arising from scientists' disavowal of ethical concerns in science. ... In a 2004 paper, neuroscientist and physician ...
Xenotransplantation—the current status and prospects
The immunologic barriers to successful xenotransplantation are primarily related to the presence of natural anti-pig antibodies in humans and NHPs that bind to antigens expressed on the transplanted pig organ (the most important of which is galactose-α1,3-galactose [Gal]), 5 and activate the complement cascade, which results in rapid ...

Xenotransplantation may offer a transformative solution to the worldwide organ shortage crisis 1,2,3. To proceed to clinical studies, a clinically ready porcine donor must be engineered and its ...
"Xenotransplantation challenges us as a society":
Xenotransplantation has come closer to clinical application. While it provides hope for patients with irreversible organ failure, it also raises ethical, psychosocial, and regulatory issues. These issues challenge us both as human beings and in our relationship to animals and should be discussed among broader society. In order to elicit well ...
Xenotransplantation literature update March 2021-March 2023
There has been an invigorated focus on unique challenges posed by pig-to-human xenotransplantation, and specific attention will be given to this aspect. In this issue, we aimed to cover the gap and compiled the most relevant publications from March 2021 to March 2023.
THE CASE FOR XENOTRANSPLANTATION
Xenotransplantation, specifically the transplantation of organs and cells from genetically-engineered pigs, could resolve this problem. Diabetic monkeys have remained normoglycemic and insulin-independent after pig islet transplantation for >1 year, and a pig heterotopic (non-life-supporting) heart transplant recently reached the one-year ...
