Over the past year, a series on commentaries have appeared in the Toxicological Sciences Forum Series related to the 2007 National Research Council (NRC) publication, Toxicity Testing in the 21st Century: A Vision and A Strategy. The first article in the series provided an overview of the vision and was accompanied by an editorial by the three editors of Toxicological Sciences. During the past year, eight invited commentaries from the academic, industrial, and regulatory sectors have provided diverse perspectives on the vision, noted challenges to its implementation, and highlighted aspects of toxicity testing that were not addressed in the original NRC report. Here, we offer a summary of the main points raised by the commentators in tabular form, identify a number of common themes, and finish the series by providing our perspective on several key issues in charting the path forward to move from discussion to action.
