Stem cells was the theme for this year's Nobel Prize in medicine or physiology wich the researchers Shinya Yamanaka (Japan) and Joseph B. Gurdon (Great Britain) now share.

Mr. Yamanaka to your left and Mr. Gurdon to your right.


Shinya Yamanaka (50) discovered that it is possible to make fully developed cells back in their development to become unripe stem cells once again, and thereby regaining their ability to grow into different kinds of cells.

These stem cells, iPSCs*, mean a new way of developing endogenous human spare parts.

Mr. Yamanaka has since his finding was published in 2006 been a hot topic in the context of the Nobel Prize.


John B. Gurdon (79), the gentleman sharing the prize, had as early as in the year of 1962 questioned the thesis on the impossibility of changing fully developed cells.

In an attempt to test his hypothesis, he replaced the nucleus in the oocyte of a frog with the nucleus of a intestinal cell from a tadpole wich resulted in the egg developing into a tadpole.

Later he also succeded in cloning grown frogs.

At Eton, Gurdon was ranked last out of 250 kids in the subject of biology.

For their work on stem cells Martin Evans, Mario R. Capecchi and Oliver Smithies got a Nobel prize back in 2007 and now for their work this duo got their part. Sad that the actual discoverers of stem cells Ernest McCulloch and James Hill did not get it yet, and McCulloh will never get it since he died the last year
