Google is trying to protect its users from advertising “dubious stem cell therapies.” The company noted that they will cease to provide a platform for those who "use people, offering them unverified treatment."

According to hightech.fm , this policy has been developed in conjunction with the US Food and Drug Administration (FDA). She fights clinics that use unproven and potentially dangerous stem cell treatments. According to the agency, hundreds of clinics across the country have begun introducing stem cell therapy, which the FDA has not approved as safe and effective.

Google explained that different types of stem cell treatments are at different stages of development. Bone marrow stem cell transplantation is a well-established treatment for a number of oncological diseases. But since then, new treatments have appeared that are just beginning to undergo clinical trials. Despite this, some clinics in the USA already offer their clients.

Such clinics “want to get clients' money, but cannot explain why their treatment methods are generally effective,” said bio-ethics expert Art Kaplan, who is the founder of the medical ethics department at the New York University School of Medicine. He calls these clinics "sketchy", meaning that they pay more attention to commercial activity, rather than real help to their patients.

“There are unscrupulous clinics that have benefited from studies of regenerative medicine and give deceptive, and sometimes corrupt, assurances to patients based on unproven, and in some cases dangerous, methods,” said FDA Commissioner Scott Gottlieb.

Over the past 15 years, more than $ 20 billion has been invested in the stem cell industry. The increase in unauthorized treatment has led the FDA to sue individual clinics.
