Ambrosia in Monterey, Calif. Is preparing to conduct the first trials of human rejuvenation using blood plasma. The method is based on the results of a study of parabiosis in mice, in which the circulatory systems of old and young animals are combined. Science reports.
The founder of the firm is the physician Jesse Karmazin. He plans to study the anti-aging effect of plasma in young people, which will be transfused into volunteers aged 35 and over. In total, 600 people will participate in the experiment, who will pay 8 thousand dollars for this. Donors must not be over 25 years old. Each recipient will receive 1.5 liters of plasma over two days. Before the procedure and one month after it, the blood of the volunteers will be tested for biochemical changes. Participants will be required to cover the costs of obtaining plasma from a blood bank, laboratory tests, insurance, and bioethics committee approval.
The experiment, however, has already been criticized by some experts. There is no clinical evidence that the trials can be successful in humans, they said. In addition, Tony Wyss-Coray, author of a 2014 study that showed the beneficial effects of blood from young mice on older mice, believes such studies are abusing people's trust and generating unnecessary public anxiety.
Tony Wyss-Coray is the founder of Alkahest at Stanford. He is conducting a series of studies on the effects of blood plasma in young people on 18 volunteers with Alzheimer's disease. The aim of the trial is to evaluate the safety of the method and its effectiveness in reducing the manifestation of symptoms. The company itself covers the costs of the participants.
