Toward Good Read-Across Practice (GRAP) Guidance

Aug 16, 2017
Grouping of substances and utilizing read-across of data within those groups represents an important data gap filling technique for chemical safety assessments. Categories/analogue groups are typically developed based on structural similarity and, increasingly often, also on mechanistic (biological) similarity. While read-across can play a key role in complying with legislation such as the European REACH

Stem Cell-Based Methods for Identifying Developmental Toxicity Potential

Aug 16, 2017
There is an increasing need for reliable, high-throughput in vitro developmental toxicity screens in both the pharmaceutical and chemical industries. Establishing predictive human cell-based assays to aid in the early discovery-phase detection of potential developmental toxicants is strongly warranted as these tests could reduce product development time and costs. Stemina authors include Jessica Palmer, Bob

A Human Induced Pluripotent Stem Cell-Based In Vitro Assay Predicts Developmental Toxicity Through a Retinoic Acid Receptor-Mediated Pathway for a Series of Related Retinoid Analogues

Aug 16, 2017
[Accepted manuscript] The relative developmental toxicity potency of a series of retinoid analogues was evaluated using a human induced pluripotent stem (iPS) cell assay that measures changes in the biomarkers ornithine and cystine. A Human Induced Pluripotent Stem Cell-Based In Vitro Assay Predicts Developmental Toxicity …

Supporting Read-Across Using Biological Data

Aug 16, 2017
Read-across, i.e., filling toxicological data gaps by relating to similar chemicals for which test data are available, is usually done based on chemical similarity. Besides structure and physico-chemical properties, biological similarity based on biological data adds extra strength to this process. In the simplest case, chemically similar substances also show similar test results in relevant
