Cohen Stanley, 1922, Year won 1986, made a significant contribution to the study of cancer..
Stanley Cohen was born in New York in 1922. At the age of 26, he received his doctorate in chemistry from the University of Michigan. He worked at the University of Colorado and in 1953 moved to Washington University in St. Louis where he undertook cancer research with Rita-Levi Montalcini. Cohen has been a professor of chemistry at Vanderbilt University since 1959.
How does man grow from a single fertilized cell into a complex arrangement of billions of cells each with its own unique function and working together in perfect synchronization? Part of the answer lies in the family of proteins known as growth factors which were first discovered by Stanley Cohen and Levi-Montalcini in the l950’s.
In awarding the 1986 Nobel Prize for medicine and physiology to Stanley Cohen and Rita Levi-Montalcini, the prize committee noted that their work was of fundamental importance in making it possible to understand the mechanisms which regulate cell and organ growth.
Stanley Cohen successfully isolated the nerve growth factor NGF from the salivary glands of rats and even devoloped antibodies against it. In 1962 he succeeded in isolating an additional, epidermal growth factor – EGF.
The very existence of growth factors was questionable prior to the research of Stanley Cohen and Rita Levi-Montalcini. Today scientists are convinced that they exist and recognize their great importance.
