Sommaire:
This book covers the origins and subsequent history of research results in which attempts have been made to clarify issues related to cellular ageing, senescence, and age-related pathologies including cancer. Cellular Ageing and Replicative Senescence revisits more than fifty-five years of research based on the discovery that cultured normal cells are mortal and the interpretation that this phenomenon is associated with the origins of ageing. The mortality of normal cells and the immortality of cancer cells were also reported to have in vivo counterparts. Thus began the field of cytogerontology.
