Alternatives to animal-derived extracellular matrix hydrogels? An explorative study with HepaRG cells in animal-free hydrogels under static and dynamic culture conditions

Frontiers in Toxicology
New approach methodologies (NAMs) aim for animal-free chemical risk assessments. However, many in vitro NAM models still depend heavily on Matrigel and collagen despite the ethical, reproducibility, and biomedical concerns regarding the use of animal ...
