In a groundbreaking medical development, a woman from Alabama has made headlines by undergoing a pig kidney transplant that lasted an impressive 130 days before being removed due to rejection by her body. Towana Looney, from Gadsden, experienced both the potential and limits of xenotransplantation as she navigated this experimental procedure, which offers hope for patients needing organ transplants. Following her surgery at NYU Langone Health on April 4, Looney returned home, expressing gratitude for the insights gained from her journey.
Despite having been put back on dialysis after the removal of the organ, Looney’s case has provided researchers with invaluable data on organ rejection processes and the challenges faced in kidney transplantation. This situation sheds light on the urgent organ shortage crisis in the U.S., where more than 100,000 individuals are currently awaiting transplants.
As the field of organ transplantation continues to evolve, Looney’s case serves as a pivotal moment in understanding the feasibility of using animal organs to save human lives, illustrating both the promise and complexities of the emerging science of xenotransplantation.

The Procedure and Initial Outcomes
In late 2024, Towana Looney made history by receiving a kidney from a genetically modified pig. This unique operation was a part of ongoing research aimed at addressing the critical shortage of human organs for transplantation. The pioneering surgery was performed at NYU Langone Health by renowned transplant surgeon Dr. Robert Montgomery and his team.
Looney’s journey began on November 25, 2024, when she underwent the transplant. In a remarkable turn of events, she maintained the pig kidney for 130 days, significantly surpassing previous benchmarks for similar procedures. During this time, Looney reported an improved quality of life, referring to herself as “superwoman” due to the extra time away from dialysis, which she had relied on since 2016 due to her underlying health conditions.
Unfortunately, by early April, her body began exhibiting signs of organ rejection, which prompted a decision by her medical team to remove the kidney. Ultimately, Looney underwent a surgery on April 4, 2025, to replace the organ with safer options. Post-surgery, she returned to her dialysis regimen while expressing her gratitude towards the medical team for allowing her to participate in groundbreaking research.
Implications for Future Transplants
The procedure that Looney underwent is part of a larger strategy to utilize genetically engineered animals, particularly pigs, as organ donors for human transplants. The promise of xenotransplantation lies in the potential to alleviate the organ shortage; currently, more than 100,000 individuals in the United States are on transplant waiting lists, with a significant number dying each year while waiting. Gaining insights from Looney’s experience may guide future protocols to improve rate of success in transplant surgeries.
The research findings drawn from Looney’s case will contribute to understanding the biological compatibility between human recipients and animal organs. Specifically, the factors that led to organ rejection in her case are being extensively reviewed, which may help refine future transplant protocols and potentially lead to longer-lasting solutions for future patients.
The intentional genetic modifications made to the pig organ, making it more compatible with the human immune system, are crucial. Scholars and scientists are delving into the combination of genetic changes and immunosuppressive therapies that could yield better outcomes in the future, as evidenced by Looney’s case.
The Case of Pig Organ Transplants
Looney is not alone in her experience; there have been several pivotal cases involving patients receiving pig organs. For instance, just a few months prior to Looney’s surgery, another patient underwent a similar transplant but unfortunately succumbed to complications. These cases raise complex discussions about the ethical considerations of using animal organs for human transplants.
In recent years, advancements in biotechnology have enabled researchers to modify pigs genetically to help bridge the gap in organ availability. These gene-edited organisms are designed to have human-like organs to decrease the likelihood of rejection. Looney’s surgery marks a significant milestone and sheds light on the viability of this approach for people who are critically dependent on transplants.
Nevertheless, the medical community remains cautious. Understanding the immunological factors behind organ rejection is a pivotal area of ongoing research. Looney’s experience may provide critical knowledge to medical professionals striving to enhance the safety and effectiveness of similar procedures in the future.
Insights from Medical Professionals
Evidence of both challenges and hope emerged from discussions with Dr. Montgomery and his colleagues. According to Dr. Montgomery, the decision to remove Looney’s pig kidney arose primarily from observations of immunological reactions and potential health risks that outweighed the benefits of attempting to salvage the organ. He emphasized that this reaction is being extensively studied.
“We did the safe thing,” he noted. “She’s no worse off than she was before this xenotransplant. In fact, she has had a break from dialysis, which is a significant comfort.” This indicates a cautious optimism among medical professionals in approaching xenotransplantation, viewing experiences like Looney’s not merely as failures, but as valuable learning opportunities.
Furthermore, Looney exhibited resilience, engaging proactively with her medical team to understand her options thoroughly. Her spirited attitude and willingness to share her journey highlight the collaborative nature of this innovative field, where patient experiences can inform future medical advancements.
The Broader Context of Organ Transplantation
The broader context of organ transplantation involves an urgent need for innovative solutions to address the growing gap between organ supply and demand. The significant number of individuals waiting for transplants indicates a crisis that demands immediate attention. More than 100,000 individuals on the waiting list face uncertainty as many succumb to their illnesses due to a lack of available organs.
Xenotransplantation represents a potential solution to this crisis by offering another alternative for patients who may not receive a viable human transplant in time. With ongoing research and experimentation, the hope is that breakthroughs in genetic engineering and immunology will facilitate successful animal-to-human organ transplants.
As Looney’s experience has illustrated, the complexities of organ rejection and individual immune responses underscore the challenges faced in making xenotransplantation a mainstream solution for patients. Nevertheless, her case contributes valuable knowledge that enhances the continual exploration of this innovative medical frontier.

Frequently Asked Questions
Question: What is xenotransplantation?
Xenotransplantation refers to the process of transplanting organs or tissues from one species to another—in this case, from animals to humans. The goal is to provide an alternative source of organs to address shortages in human donations.
Question: Why was Looney’s kidney removed?
Looney’s kidney was removed because her body started rejecting the organ. Following the rejection, her medical team deemed it safer to remove it rather than attempt to salvage the transplant, which could have posed additional health risks.
Question: How does genetic modification play a role in organ transplants?
Genetic modification aims to alter the genetic makeup of donor animals, which can help make their organs more compatible with the human immune system. This modification can potentially reduce the likelihood of organ rejection in human recipients.
