Scientific Focus
Peter Gruss's work focused on gene regulation processes. He was particularly interested in the genetic and cellular-biological building blocks that switch genetic programmes on and off in tumour viruses and in the course of embryonic development. In experiments on mice, he successfully identified significant controlling genes (known as Pax genes) which regulate the development of various organs. A study of the pancreas which he conducted enabled him to detect genes involved in the development of insulin-producing islets of Langerhans. This also provided the basis for differentiating stem cells in insulin-producing cells.

Famous quotes containing the words scientific and/or focus:
“There is one great fact, characteristic of this our nineteenth century, a fact which no party dares deny. On the one hand, there have started into life industrial and scientific forces which no epoch of former human history had ever suspected. On the other hand, there exist symptoms of decay, far surpassing the horrors recorded of the latter times of the Roman empire. In our days everything seems pregnant with its contrary.”
—Karl Marx (1818–1883)
“If your child is going to develop a healthy personality with the capacity to remain intact and grow, she must learn how to test reality, regulate her impulses, stabilize her moods, integrate her feelings and actions, focus her concentration and plan.”
—Stanley I. Greenspan (20th century)
