title: Animal models for the study of the developmental origins of health and disease.
abstract: Human epidemiological studies have indicated that the risk of developing non-communicable diseases in later life may be related to exposures during the developmental period. Developmental life is a vulnerable period of the lifespan during which adverse environmental factors have the potential to disturb the processes of cell proliferation and differentiation or to alter patterns of epigenetic remodelling. Animal models have been instrumental in demonstrating the biological plausibility of the associations observed in human populations, providing proof of principle to the theory of the developmental origins of health and disease (DOHaD). A variety of large- and small-animal models have made important contributions to the field, providing strong evidence of a causal relationship between early-life exposures and metabolic risk factors in later life. Studies of animal models are continuing to contribute to improving the understanding of the mechanisms of the developmental origins of disease. All models have their advantages and disadvantages, and the model that is most appropriate for any particular study is hypotheses dependent. The present review aims to briefly summarise the contributions that animal models have made to the DOHaD field, before reviewing the strengths and weaknesses of these animal models. It is proposed that the integration of evidence from a variety of different models is required for the advancement of understanding within the field.
