Epithelial cells lining the airway, skin, and digestive tract are the interface between the body and the environment and serve both as physical barrier and key player in the toxicological response to chemical and environmental exposures. The three epithelial barriers are target organs of toxicity, modulate the absorption of chemicals from the environment, mediate local and systemic immunological responses, and participate to xenobiotic biotransformation. The epithelium functions in the context of a microenvironment, which is regulated by interactions between epithelial cells, stromal cells, and the extracellular matrix; however, most in vitro and high-throughput models of the epithelium utilize monocultures grown under standard “cells on plastic” conditions. As a result, these traditional in vitro epithelial models may not accurately recapitulate the topological organization, morphological hallmarks, and cell-cell communication that would normally be present in vivo. These limitations can be overcome through the development and application of three-dimensional, multi-cell type organotypic in vitro models, which more accurately represent the in vivo epithelial microenvironment, in pharmacology and toxicology studies. The development of organotypic epithelial models has advanced considerably in recent years and the application of these models has the potential to transform the use of in vitro models in the field of toxicology.

About the Meeting:

This meeting will provide opportunities for toxicologists that are interested in, or currently using, organotypic models and technology developers to meet face-to-face to foster collaborations that will move the field forward. In addition to presenting the state of the science, this conference will include moderated discussion sessions for attendees and speakers to discuss advances, future needs and data gaps, and applications of these models in the investigation into the cellular and molecular mechanisms of toxicity. The presentations will focus around developments in in vitro organotypic airway, skin, and intestinal epithelial models that may inform mechanistic understanding by toxicologists across academia, government, and industry. Further, presentations will discuss practical considerations when incorporating these tools into next generation in vitro research and safety evaluation.

The American Society for Cellular and Computational Toxicology (ASCCT) recently held its 6th Annual Meeting at the headquarters of one of its founding organizations, the Institute for In Vitro Sciences. Meeting attendees participated in several oral presentation sessions, a poster session, panel discussion, awards ceremony, and mentoring event, all focused on the development and implementation of alternative, nonanimal toxicology science and policy. As in 2016, the meeting was held at a time and place to coincide with the Science Advisory Committee for Alternative Toxicological Methods (SACATM), an advisory group for the US-based Interagency Coordinating Committee for the Validation of Alternative Methods. This structure fits well with ASCCT’s mission to increase the cooperation and dialog between toxicologists from government, industrial, academic, and non-profit organizations.

The meeting started September 21st with a focus on acute systemic toxicity thanks to a pair of plenaries touching on policy and scientific advances and challenges. Anna Lowit from the US EPA presented EPA-OPP's Initiative to Modernize the Acute "6-Pack” and Dan Wilson from Dow Chemical Company presented a Progress Report on Efforts to Replace Acute Systemic Toxicity Tests with Mechanistic Alternative Approaches. After several talks from submitted abstracts on acute systemic toxicity, updates on FDA CFSAN efforts to modernize regulatory toxicology and the establishment of a new Canadian alternatives center were provided by Suzanne Fitzpatrick from the US Food and Drug Administration and Charu Chandrasekera from the Canadian Centre for Alternatives to Animal Methods, respectively.

The day ended with the awarding of the Tox21 Student Award to Wenyi Wang from Rutgers University for her work titled Mechanistic Evaluation of Chemicals that Induce Oral Acute Toxicity by Mitochondrial Membrane Disruption: Big Data Profiling and Analysis; the Edward Carney Award for Predictive Toxicology was given to Ellen Garcia from Virginia Tech for her presentation Characterization of two lung cell lines for use in cell division focused, single-cell toxicity assays.

Under the Lautenberg Chemical Safety Act (LCSA), the EPA is tasked with creating a strategic plan for developing and implementing methods which reduce and replace vertebrate animal testing. The second day of the meeting began with a plenary providing a Progress Report on Development of a Strategic Plan to Reduce, Refine or Replace Use of Vertebrate Animal Testing Under the Lautenberg Act from Gino Scarano of US EPA. Another platform presentation session followed Dr. Scarano’s presentation, and the day was rounded out with an active and engaging closing panelist and audience discussion to provide EPA feedback and advice, and discuss views, roles, and responsibilities of all stakeholders involved in Lautenberg Act implementation.

Thanks to all who attended, spoke, and participated in the planning! A full report will be put together for publication in the coming months, and all are welcome to join in the planning for the 7th Annual Meeting in the fall of 2018. Contact Secretary Kristie Sullivan to get involved.

Thank you to all who helped make our fifth meeting the best yet. Attendees were treated to plenary lectures on read across by Dr. Thomas Hartung of Johns Hopkins University and on stem cells in toxicology by Dr. Mahendra Rao of Mahendra Rao, LLC. Sixteen presentations showcasing advances in the field of toxicology, as well as a mentoring session with young scientists, a poster session, and dynamic panel discussion rounded out the program.

We were honored to host the wife and brother of the late Dr. Edward Carney to award the 2nd annual Ed Carney Award for Predictive Toxicology, which went to Emma Bowers for her presentation Modeling a complex in vivo response in vitro: Exploring heterogeneity and mechanisms associated with ozone adaptation. After winning the William and Eleanor Cave Award for his career achievements in in vitro toxicology, Dr. Ray Tice established the Tox21 Student Award, which will be given for the next five years. This year, the award went to Ellen Garcia for her presentation Single-cell analysis reveals that silver nanoparticle exposure leads to multi-nucleation through defective cell division.

Finally, members elected Ellen Berg to the Board of Directors
