Increasing Predictivity in Toxicity and Safety Pharmacology

Applying Relevant Human Model Cells

The toxicity and safety assessment of new pharmaceuticals and chemicals is a complex process that incorporates information from in silico analyses, in vitro studies, and animal testing. Over the past decade there has been an growing need for validated, physiologically relevant, and predictive human model cells. Several factors have contributed to this need:

iCell® and MyCell® Products offer a novel approach to in vitro safety testing that overcomes many limitations of existing models. Some of the benefits include:

  • Biological relevance – human cell models
  • Purity – ensures reproducible and consistent results
  • Scalability – our production process allows for large number of cells that eliminate the need for repeat sourcing and validation

The importance of iCell and MyCell products to the field of safety assessment is best evidenced by a proposed new regulatory paradigm (Gintant G, Sager PT, Stockbridge N, 2016, Sager PT, et al., 2014) to validate and standardize the use of stem cell-derived cardiomyocytes in in vitro assays for predicting cardiac arrhythmia.
