Fear of Immune Response to Induced Stem Cells Overstated

Induced pluripotent stem cells

Scientists report that induced pluripotent stem cells (iPS) have a similar immune response in mice as embryonic stem cells (ES).

The exact causes of infertility, which can affect around 10% of couples, are often unknown. In some cases, it may be a result of the body’s inability to produce viable gametes. A new study of the development of germ cells from humans could help scientists learn how to create them in the laboratory.

Just days after Kyoto University biologist Shinya Yamanaka won the Nobel Prize for his discovery of induced pluripotent stem cells (iPS), Hisashi Moriguchi, a visiting researcher at the University of Tokyo, claimed to have modified that technology to treat a person with terminal heart failure. Eight months after the treatment, the patient was reported to be healthy.
