This module will discuss how ToxCast and Tox21 technologies can be used in practice. The US EPA Endocrine Disruptor Screening Program will be discussed in detail and we will demonstrate how the ToxCast platform replaced in vivo tiered approaches in EDSP and, thus, acelerate the process of . In the second lesson of this module, the development of in silico models for toxicity testing will be discussed.

The first lesson in this module will explain the concept of read-across, why it is important for regulatory risk assessment, and how it can be implemented by industry in response to REACH legislation. The organotypic cultures lesson will teach you about existing in vitro cell-based models starting from simple monolayer cultures of cell lines and ending with complex combined organ-on-a-chip and human-on-a-chip approaches.

In this module you will learn about important component of in vitro toxicology such as in vitro to in vivo extrapolation (IVIVE) and physiologically based biokinetic modeling. You will learn why it is important to consider biokinetics in vitro and see some example of biokinetics modeling in vitro. This lesson will also give you a biometry prospective of in vitro toxicology. You will learn which methods can be used to analyze big data.
