Hans SpemannBorn 27 Jun 1869; died 12 Sep 1941 at age 72.German embryologist who was awarded the Nobel Prize for Physiology and Medicine (1935) for his discovery of embryonic induction, an effect involving several parts of the embryo in directing the development of the early group of cells into specific tissues and organs. Working extensively on the early development of the newt, he showed that the in the earliest stage, tissues may be transplanted to different areas of the embryo, and it then develops based on the new location and not from where it came. For example, early tissue cut from an area of nervous tissue might be moved to an area of skin tissue where it then grows into the same form as the surrounding skin. |
