In China, Prisoners of Conscience Are Being Murdered for Their Organs to Fuel Transplant Tourism
Organ transplantation can dramatically improve or save lives. A heart transplant can literally give a person a new lease of life, while a kidney transplant frees the recipient from lengthy spells on dialysis.
A people's tribunal in London has recently found that in China, organs are sourced from prisoners of conscience who are killed on demand to fuel the lucrative organ transplantation market.
To protect the integrity of organ transplantation, there are strict ethical guidelines. When organs are sourced from deceased persons, the donation must be voluntary, donors must die naturally before any organs are taken, and death must not be hastened to provide organs. These ethical guidelines protect donors and provide assurance to transplant recipients that their organs have been sourced ethically.
However, not all countries follow these ethical guidelines. A people's tribunal in London has recently found that in China, organs are sourced from prisoners of conscience who are killed on demand to fuel the lucrative organ transplantation market. This conclusion, reported at the United Nations Human Rights Council on September 24, was not reached lightly.
The independent China Tribunal, made up of four human rights lawyers, one surgeon with transplant experience, an academic who specialises in China studies and a businessman with human rights interests, spent over a year looking at written materials and heard evidence from over 50 witnesses in five days of hearings. Their grim conclusion, that prisoners of conscience are murdered for their organs, confirms the findings of earlier investigations.
Questions first arose over China's transplant system when the numbers of transplants rose dramatically after 2000. Transplant capacity rapidly increased; new infrastructure was built and staff were trained. Hospital websites offered livers, hearts and kidneys available in a matter of days or weeks, for a price. Foreigners were encouraged to come to China to avoid lengthy transplant waiting lists in their home countries.
At the time, it was a mystery as to how China had a ready supply of organs, despite having no volunteer donation system. Eventually, in 2006, the Chinese government stated that organs were removed from prisoners who had been found guilty and sentenced to the death penalty. But this explanation did not ring true. Death row prisoners often have poor health, including high rates of infectious diseases, making them poor candidates for donation. By contrast, the organs offered for sale were promised to be healthy.
In 2006, the first clues about the source of the organs emerged. A woman called Annie reported that her surgeon husband had been present during organ removal from Falun Gong practitioners who were still breathing as the scalpels cut into them. A subsequent investigation by two Canadian human rights lawyers examined multiple sources of evidence, concluding that murdered Falun Gong practitioners were indeed the source of the organs.
The evidence included testimony from practitioners who had been imprisoned, tortured, and later released. During imprisonment, many practitioners reported blood and other medical tests examining the health of their organs—tests that were not performed on any other prisoners. Phone calls made to Chinese hospitals by investigators posing as patients were offered rapid access to fresh organs from Falun Gong practitioners. The organs were guaranteed to be healthy, as the practice forbids smoking tobacco and drinking alcohol.
Since 2006, evidence has continued to accumulate. China has a huge transplant industry and no plausible source of voluntary organ donations. Unlike the rest of the world, Chinese waiting times remain very short. Foreigners continue to come to China to avoid lengthy waiting lists. Prisoners of conscience, including Tibetans and Uyghurs as well as Falun Gong practitioners, are still being imprisoned and medically tested.
The Chinese government continues to deny these crimes, claiming that there is a volunteer donor system in place.
The China Tribunal heard from Uyghur witnesses who had recently been inside the notorious labour camps (also called "re-education" centers) in Xin Xiang. The witnesses reported terrible conditions, including overcrowding and torture, and were forced to have medical examinations. They saw other prisoners disappear without explanation following similar medical tests. As recently as 2018, doctors in Chinese hospitals were promising potential patients healthy Falun Gong organs in taped phone calls.
The Chinese government continues to deny these crimes, claiming that there is a volunteer donor system in place. In the Chinese system, prisoners are counted as volunteers.
China's forced organ harvesting from prisoners of conscience has international implications. A recent study found that most published Chinese transplant research is based on organs sourced from prisoners. International ethical guidance prohibits taking organs from prisoners and prohibits publication of research based on transplanted material from prisoners. The authors of that study called for retractions of the papers, some of which are in well-known scientific journals. So far Transplantation and PLOS One are among the journals that have already retracted over twenty articles in response. On questioning from the editors, the authors of the papers failed to respond or could not verify that the organs in the transplant research came from volunteers.
The international community has a moral obligation to act together to stop forced organ harvesting in China.
The China Tribunal concluded that forced organ harvesting remains China's main source of transplant organs. In their view, the commission of Crimes Against Humanity against the Uyghurs and Falun Gong has been proved beyond reasonable doubt. By their actions, the Chinese government has turned a life-saving altruistic practice into our worst nightmare. The international community has a moral obligation to act together to stop forced organ harvesting in China, and end these crimes against humanity.
The Cellular Secrets of “Young Blood” Are Starting to Be Unlocked
The quest for an elixir to restore youthful health and vigor is common to most cultures and has prompted much scientific research. About a decade ago, Stanford scientists stitched together the blood circulatory systems of old and young mice in a practice called parabiosis. It seemed to rejuvenate the aged animals and spawned vampirish urban legends of Hollywood luminaries and tech billionaires paying big bucks for healthy young blood to put into their own aging arteries in the hope of reversing or at least forestalling the aging process.
It was “kind of creepy” and also inspiring to Fabrisia Ambrosio, then thousands of miles away and near the start of her own research career into the processes of aging. Her lab is at the University of Pittsburgh but on this cold January morning I am speaking with her via Zoom as she visits with family near her native Sao Paulo, Brazil. A gleaming white high rise condo and a lush tropical jungle split the view behind her, and the summer beach is just a few blocks away.
Ambrosio possesses the joy of a kid on Christmas morning who can't wait to see what’s inside the wrapping. “I’ve always had a love for research, my father was a physicist," she says, but interest in the human body pulled her toward biology as her education progressed in the U.S. and Canada.
Back in Pittsburgh, her lab first extended the work of others in aging by using the simpler process of injecting young blood into the tail vein of old mice and found that the skeletal muscles of the animals “displayed an enhanced capacity to regenerate.” But what was causing this improvement?
When Ambrosio injected old mice with young blood depleted of EVs, the regenerative effect practically disappeared.
The next step was to remove the extracellular vesicles (EVs) from blood. EVs are small particles of cells composed of a membrane and often a cargo inside that lipid envelope. Initially many scientists thought that EVs were simply taking out the garbage that cells no longer needed, but they would learn that one cell's trash could be another cell's treasure.
Metabolites, mRNA, and myriad other signaling molecules inside the EV can function as a complex network by which cells communicate with others both near and far. These cargoes can up and down-regulate gene expression, affecting cell activity and potentially the entire body. EVs are present in humans, the bacteria that live in and on us, even in plants; they likely communicate across all forms of life.
Being inside the EV membrane protects cargo from enzymes and other factors in the blood that can degrade it, says Kenneth Witwer, a researcher at Johns Hopkins University and program chair of the International Society for Extracellular Vesicles. The receptors on the surface of the EV provide clues to the type of cell from which it originated and the cell receptors to which it might later bind and affect.
When Ambrosio injected old mice with young blood depleted of EVs, the regenerative effect practically disappeared; purified EVs alone were enough to do the job. The team also looked at muscle cell gene expression after injections of saline, young blood, and EV-depleted young blood and found significant differences. She believes this means that the major effect of enhanced regenerative capacity was coming from the EVs, though free floating proteins within the blood may also contribute something to the effect.
One such protein, called klotho, is of great interest to researchers studying aging. The name was borrowed from the Fates of Greek mythology, which consists of three sisters; Klotho spins the thread of life that her sisters measure and cut. Ambrosio had earlier shown that supplementing klotho could enhance regenerative capacity in old animals. But as with most proteins, klotho is fragile, rapidly degrading in body fluids, or when frozen and thawed. She suspected that klotho could survive better as cargo enclosed within the membrane of an EV and shielded from degradation.
So she went looking for klotho inside the EVs they had isolated. Advanced imaging technology revealed that young EVs contained abundant levels of klotho mRNAs, but the number of those proteins was much lower in EVs from old mice. Ambrosio wrote in her most recent paper, published in December in Nature Aging. She also found that the stressors associated with aging reduced the communications capacity of EVs in muscle tissue and that could be only partially restored with young blood.
Researchers still don't understand how klotho functions at the cellular level, but they may not need to know that. Perhaps learning how to increase its production, or using synthetic biology to generate more copies of klotho mRNA, or adding cell receptors to better direct EVs to specific aging tissue will be sufficient to reap the anti-aging benefits.
“Very, very preliminary data from our lab has demonstrated that exercise may be altering klotho transcripts within aged extracellular vesicles" for the better Ambrosio teases. But we already know that exercise is good for us; understanding the cellular mechanism behind that isn't likely to provide additional motivation to get up off the couch. Many of us want a prescription, a pill that is easy to take, to slow our aging.
Ambrosio hopes that others will build upon the basic research from her lab, and that pharmaceutical companies will be able to translate and develop it into products that can pass through FDA review and help ameliorate the diseases of aging.
Podcast: Should Scientific Controversies Be Silenced?
The "Making Sense of Science" podcast features interviews with leading medical and scientific experts about the latest developments and the big ethical and societal questions they raise. This monthly podcast is hosted by journalist Kira Peikoff, founding editor of the award-winning science outlet Leaps.org.
The recent Joe Rogan/Spotify backlash over the misinformation presented in his recent episode on the Covid-19 vaccines raises some difficult and important bioethical questions for society: How can people know which experts to trust? What should big tech gatekeepers do about false claims promoted on their platforms? How should the scientific establishment respond to heterodox viewpoints from experts who disagree with the consensus? When is silencing of dissent merited, and when is it problematic? Journalist Kira Peikoff asks infectious disease physician and pandemic scholar Dr. Amesh Adalja to weigh in.
