One of the most important contemporary issues in modern toxicology is the adequacy and suitability of scientific data derived from laboratory animals for human toxicological risk assessment. Whole animal model sys-tems are utilized because the direct use of human beings for toxicological research and testing is severely limited by ethical considerations. Sources of human toxicity data for toxicological evaluations come from anecdotal reports on people accidentally exposed to toxic chemicals, from epidemiological studies of occupationally exposed populations, and occasionally the general public, and from clinical trials of pharmaceuticals in which chemical agents are tested in human populations before their introduction for general use. Skin testing of commercial products, such as cosmetics, in human volunteers is another area of human testing. However, these mechanisms are not available for broad application to toxicological research and testing. In all of these cases, human data are obtained only after the chemical is introduced into the human environment. By utilizing in vitro methodologies, the toxicological response of human tissues to xenobiotics can be directly assessed under controlled experimental conditions in advance of human exposure. This approach has the distinct advantage that it eliminates the necessity to extrapolate experimental observations from animal models to man (Fig. 1). Thus, many of the confounding factors that make interspecies extrapolation a difficult task, particularly when there are conflicting data from various species, are eliminated. This is not to say that in vitro toxicological research and testing employing human tissues and cells can eliminate all questions of extrapolation. Even when a particular in vifro model has been validated vis-&vis in vivo responses to a variety of chemicals, one is still left with the question of how to relate an EC50 measurement in vitro to an equivalent dose to humans via a particular route of exposure (inhalation, ingestion, dermal contact. or parenteral for pharmaceuticals). A major toxicological challenge for the future will be to develop the quantitative methodology to predict in viva exposure-risk relationships from in vitro dose-response relationships. In the meantime, the use of human tissues for irz pi-
