Adult Stem Cells and Cancer
In recent years, acceptance of the concept of adult stem cells has increased. There is now a hypothesis that stem cells reside in many adult tissues and that these unique reservoirs of cells not only are responsible for the normal reparative and regenerative processes but are also considered to be a prime target for genetic and epigenetic changes, culminating in many abnormal conditions including cancer.

Famous quotes containing the words adult, stem, cells and/or cancer:
“This is no argument against teaching manners to the young. On the contrary, it is a fine old tradition that ought to be resurrected from its current mothballs and put to work...In fact, children are much more comfortable when they know the guide rules for handling the social amenities. Its no more fun for a child to be introduced to a strange adult and have no idea what to say or do than it is for a grownup to go to a formal dinner and have no idea what fork to use.”
—Leontine Young (20th century)
“Ignorance, the root and stem of all evil.”
—Plato (c. 427347 B.C.)
“The twelve Cells for Incorrigibles ... are also carved out of the solid rock hill. On the walls of one of the cells human liberty is clearly inscribed, with the liberty in significant quotation marks.”
—Administration in the State of Ariz, U.S. public relief program (1935-1943)
“I wish more and more that health were studied half as much as disease is. Why, with all the endowment of research against cancer is no study made of those who are free from cancer? Why not inquire what foods they eat, what habits of body and mind they cultivate? And why never study animals in health and natural surroundings? why always sickened and in an environment of strangeness and artificiality?”
—Sarah N. Cleghorn (19761959)
