ABSTRACT
Aging is a complex biological process marked by the gradual degradation of cellular functions and tissues due to multiple factors, including oxidative stress, genomic instability, telomere shortening, epigenetic changes, and cellular senescence. Understanding these aging mechanisms is crucial for developing strategies to extend healthy lifespans and combat age-related diseases. Various experimental models have been employed to investigate aging, ranging from in vitro cell cultures to single-cell organisms and complex primates. Each model has distinct advantages and limitations, making them valuable tools in aging-related research. This review provides an overview of experimental aging models, including in vitro systems, invertebrate models, and preclinical vertebrate models, and discusses their pros and cons. We assess these models’ ability to replicate the complexities of human aging and their translational potential. Emphasizing the importance of considering alternative animal models, we aim to gain a more comprehensive understanding of aging processes and their relevance to human health.
Keywords: Aging; animal models; experimental models
