The Stem Cell Divide Gallery Photo 1

Using His Head
Photograph by Max Aguilera-Hellweg, M.D.

Pathologist Rudolf Virchow is credited with being the first to suggest, in the 1800s, that disease begins at the cellullar level. A human skull displayed at the Berlin Museum of Medical History, which houses Virchow's collection of medical specimens, is the product of stem cells—the immature cells that give rise to every part of the human body. (Read Aguilera-Hellweg's field notes.)
