Aging is a process of degenerative change that occurs as a result of time-related accumulation, associated with age-related diseases. Understanding the causes and mechanisms of aging and finding drugs that can effectively delay aging and prevent and cure age-related diseases currently present a great challenge for humans. Aging animal models thus represent an important tool in aging research, and various aging animal models have been created using different aging mechanisms. These different models having specific advantages and disadvantages, making them suitable for different research purposes. This review considers aging rodent models to provide information for aging research.
