A seminal research paper in the saga of questionable stem cell medical treatments has just been retracted, largely due to ethical concerns.
The 2017 paper touted the safety of injecting stem cells derived from patients’ fat cells into their arthritic knees. It implied that the treatment was successful in its sample of 10 patients.
Its purported conclusions were then broadcast by U.S. Stem Cell, a Florida clinic that has since come under legal fire by the Food and Drug Administration. In 2019, the FDA obtained a permanent injunction from federal court forbidding the firm from continuing its treatments.

A team of scientists from the U.S., China, and Spain reported Thursday they have created the first embryos that were part human and part monkey and kept them alive for up to 20 days in laboratory dishes.
The ethically controversial creation of chimeras containing cells from multiple species is part of a drive to make experimental models to help scientists better understand early development, devise new treatments for human disease, and possibly find methods to grow organs for transplant inside other animals, such as pigs or sheep. Such chimeras can be used in experiments that can’t be done with human embryos, for example, but combining human cells with those of primates ushers in new and urgent ethical concerns.

From Central America to Ukraine, unlicensed clinics are offering stem cell therapies as a treatment for autism.
Stem cells are used mainly to treat blood disease. Their effectiveness on autism is unproven and the FDA has not licensed their use for the condition.
One prominent clinic providing such treatment is Panama s Stem Cell Institute, whose founder has celebrity backing.
Experts told Business insider the clinic gains legitimacy from a program at Duke University researching stem cells and autism.
Parents seeking treatment for autistic children at unlicensed clinics cite Duke s work as a justification, although it has produced no proof the treatments work.
