Overview: developmental toxicology: new directions.

Abstract

Since regulatory agencies began implementing the use of standardized developmental toxicology protocols in the mid-1960s, our knowledge base of embryo-fetal development and technologies for experimentation has grown exponentially. These developmental toxicology protocols were a direct result of the thalidomide tragedy from earlier that decade, when large numbers of women were exposed to the drug and over 10,000 cases of phocomelia resulted. In preventing a recurrence of such tragedies, the testing protocols are immensely successful and the field of toxicology has been dedicated to using them to advance safety and risk assessment of chemicals and pharmaceuticals. Recently, our perspectives on toxicity testing have been challenged by a growing awareness that while we have excelled in hazard identification, we are in dire need of improved methodologies for human health risk assessment, particularly with respect to the large numbers of environmental chemicals for which we have little toxicology data and to the growing sentiment that better alternatives to whole animals tests are needed. To provide a forum for scientists, researchers, and regulators, the Developmental and Reproductive Toxicology Technical Committee of the Health and Environmental Sciences Institute organized a 2-day workshop titled "Developmental Toxicology-New Directions" to evaluate lessons learned over the past 30 years and discuss the future of toxicology testing. The following four articles describe different presentations and discussions that were held over the course of those 2 days.
