title: The common marmoset (Callithrix jacchus) as a model in toxicology.
abstract: The common marmoset, Callithrix jacchus, is the smallest nonhuman primate commonly used in biomedical research. Marmoset characteristics and propensities have enabled them to be used in a wide range of research as a model of human disease, physiology, drug metabolism, general toxicology, and reproductive biology. This paper provides a general overview of the marmoset with special emphasis on the benefits and disadvantages of this species as a model for inclusion in preclinical drug development programmes. In view of its small size in comparison with other nonrodent species marmosets have become of value for toxicology studies with biotechnology products where compound supply is limited. In general toxicology studies, marmosets have been successfully used to meet regulatory endpoints also for specific investigatory purposes. The widespread use of this species has allowed extensive background information to become available and a summary of the most frequently measured parameters are presented. Marmosets apparently represent an interesting animal model for comparative research on primate reproductive physiology. However, several basic aspects of reproductive processes exhibit cardinal discrepancies to those described for macaques and human. Thus, from the viewpoint of reproductive toxicology, the relevance of the marmoset primate model for human reproduction remains unclear to date and further research is obviously needed. Given our current knowledge of marmoset reproductive features, the use of this animal model cannot be recommended for reproductive toxicology assessment.
