The Society of Toxicology in conjunction with the US FDA Center for Food Safety and Applied Nutrition (CFSAN) have partnered to provide this colloquia series. The series presents scientific information that is high-quality, cutting-edge, future-oriented toxicological science to provide a well-grounded foundation to inform the work of US FDA employees.
On April 19, 2019, SOT and the US FDA hosted a colloquium on "Alternative Methods for Predictive Safety Testing: 3D Bioprinted Tissue Models."
Bioprinting of 3D human tissues is a newly developing field that is currently being pursued by private industry, academia, and government. Human 3D bioprinted tissues represent a valuable in vitro approach for chemical, personal care product, cosmetic, and preclinical toxicity/safety testing. Bioprinting applications are appealing alternative methods for cosmetics testing especially given the current regulatory situation in the European Union that bans animal testing on new cosmetic products. Bioprinting of skin, liver, and kidney is already appearing in toxicity testing applications for chemical exposures and disease modeling. The use of 3D bioprinted tissues and organs may provide future alternative approaches for testing that may more closely resemble and simulate intact human tissues to more accurately predict human responses to chemical and drug exposures.
