The 2007 Nobel prize for medicine or physiology has been awarded to a stem-cell research team, the Karolinska Institute said today.
Mario Capecchi, Martin Evans and Oliver Smithies won the prestigious 10 million Swedish crown (€1.09 million) prize for their work on introducing genetic changes in mice using embroynic stem cells.
Mr Capecchi was born in Italy and is a US citizen, and both Mr Evans and Mr Smithies are British-born.
Medicine is traditionally the first of the Nobels awarded each year. The prizes for achievement in science, literature and peace bearing the name of Alfred Nobel were first awarded in 1901 according to the will of the Swedish dynamite millionaire.
