Adult man consists of billions of cells. However, he begins from a single cell which contains the genetic material coding for the complete individual. The first cell divides, and in the beginning, the daughter cells are identical. Soon, however, the cells begin to exhibit slightly different characteristics. This unique specialization of cells is te...
The discovery of nerve growth factor (NGF) in the beginning of the 1950’s is a fascinating example of how a skilled observer can create a concept out of apparent chaos. Until this time, experimental neurobiologists did not understand how the development of the nervous system was regulated to result in the final complete innervation of the body. The...
In 1953, biochemist Stanley Cohen, joined the research group in St. Louis. Three years later they had purified a nerve growth-promoting extract from mouse tumour which contained both protein and nucleic acids. To determine which of these components was active, Stanley Cohen added snake venom containing a high concentration of a nucleic acid-degradi...
NGF is found in mammals, birds, reptiles, amphibians and fishes. Many cell types in these species synthesize and release NGF during development. The growth of nerve fibres is stimulated via this mechanism. Nerve fibres grow towards the source of NGF which is taken up in the fibre ends and transported back to the nerve cell body. One can imagine tha...
During the course of his studies of NGF Stanley Cohen observed an unexpected acceleration of development when he injected salivary gland extract to newborn mice. The mice displayed precocious eyelid opening and tooth eruption. The explanation was that the salivary gland extract contained another growth factor apart from NGF. Cohen termed this subst...
During the last decade, several growth factors have been isolated and characterized by different research groups. For example, somatomedin or insulin-like growth factor, which mediates the growth-promoting effect of growth hormone, was isolated from human plasma. Platelet derived growth factor (PDGF) was isolated and shown to stimulate growth of me...
Clarification of the mechanisms regulating the growth and survival of cells as well as their differentiation are of great interest to basic science. However, this knowledge can be expected to improve our understanding of the pathogenesis of several clinical disorders such as malformation and errors of development, degenerative changes such as occur...

As of 2021, the prize has been awarded to 224 individuals, twelve of them were women (Gerty Cori being the first to be awarded in 1947). [7] There have been nine years in which the Nobel Prize in Physiology or Medicine was not awarded (1915–1918, 1921, 1925, 1940–1942).
