I merely maintain that cells in an >organism have to compete in the organism's body environment as they have to >in nature. If one looks at the physiological changes that take place in >animals as they age you actually see the success of cells able to compete >more effectively in a changing environment.

Poison is >injected into a patient that makes the environment unsuitable for cancer >cells. This is called chemotherapy. What Hayflick and others observe in >vitro is that cells with a limited lifetime compete more effectively for >resources than cells with an extended lifetime. It is a well known fact that >cells in vitro undergo substantial changes. Jan (John) Coetzee Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=3196
