This title provides updated knowledge on the basic features and mechanisms of cellular ageing. Contributions consider genetic and environmental factors, failure of genetic and cellular repair mechanisms, and the epigenetic modifications that determine the final lifespan of cells. The book also provides an understanding on how aging mechanisms in mice, a most frequently used model, differ with that of humans who receive better tumour surveillance because of stringent controls on ageing mechanisms. It also appraises the use of modern technology for ageing studies and its intervention. This book serves as an excellent reading on cellular ageing for undergraduate students, researchers and experts of this area.
