Stem cells help prevent death

Bioquark is about to begin a trial in which he will try to return patients with brain death to life using stem cells. The controversial study raises numerous scientific and ethical issues, which involve many experts in the field. All points to the fact that scientists set ever higher goals when it comes to the human body – first the world’s first human transplantation, then the fight against aging, and now this is the complete abolition of death. Yes, you read it right. A company called Bioquark decided to bring back people with clinically dead brains. The Philadelphia biotechnology company is expected to launch the project later this year.

Initially, the test was planned to be held in 2016 in India, but was not allowed. Assuming that the plan will remain the same, scientists will take 20 patients who will undergo various types of treatment. First, there will be an injection of stem cells that will be isolated from the patient’s own blood or fat. Then a protein mixture will be introduced into the spinal cord, which will stimulate the growth of new neurons. Laser therapy and nerve stimulation will be performed for 15 days to induce neurons to form bonds. Meanwhile, scientists will monitor the behavior and EEG for changes caused by treatment.

r described dozens of such cases and notes that the method may have partial success in some patients in a coma. But coma and brain death are different things, and the Bioquark process raises more questions than answers.

One of the problems that scientists find in this study is informed consent. As a participant in the tests, he will be able to give his consent and how the scientists will sign their work – given that the participants are legally dead – how then can they finally confirm the death of the brain? What will happen if the brain activity is partially restored? What will be the patient’s mental state? Is it possible to damage the brain even more?

In 2016, neurologist Ariana Lewis and bioethical Arthur Kaplan wrote that this test is “doubtful,” “has no scientific basis,” and “at best ethically controversial, and at worst – is openly unethical.” Dr. Cooper also doubts the methods of Bioquark and does not believe that they will help a patient with a dead brain. This method assumes the presence of a functional brainstem – the structure through which motor neurons pass before it is correctly connected to the bark. If there is no functional brainstem, nothing will come out.

Surgeon-pediatrician Charles Cox, not participating in Bioquark, agrees with Cooper: “This is not the craziest thing I’ve ever heard, but I think that the probability of success is close to zero. I think the resurrection of someone technically would be a miracle. “
