Nobel Stem Cells

Nobel Prize in Medicine awarded for induced stem cells

This year, the award was awarded to John Gardon (Sir John B. Gurdon) and Shinya Yamanaka (Shinya Yamanaka) for their work in the field of developmental biology and the production of induced stem cells. The award ceremony is scheduled for December 10, 2012.

Sir John Gardon is a British biologist known for his work on cell nucleus transplantation. He was born in 1933, and graduated from Oxford University in 1960. The scientist received his doctorate from the California Institute of Technology. In 1962, Gardon conducted an experiment in which he replaced a nucleus from a frog egg with a nucleus taken from an intestinal cell. Subsequently, normal tadpoles developed from such an egg. As a result of the experiment, evidence was obtained that the genome of highly specialized cells stores information sufficient for the operation of all cells of the body, and their specialization can be reversible.

Shinya Yamanaka was born in Osaka in 1966. He graduated from Kobe University, and defended his doctoral thesis at Osaka University in 1962. The research for which Yamanaka received the Nobel Prize was conducted 40 years after Gardon's experiments. In 2006, a Japanese scientist published an article with co-authors in which he showed that by activating only four genes in connective tissue cells, they can be turned into stem cells. Subsequently, any cells of the body can develop from such cells.
