In our group, new cell models and endpoints are being established and used to obtain information relevant for human health and safety without animal experiments. One example is the evaluation of new flame retardants, synthesized and developed to replace poly-brominated PBDE compounds that are being phased out because of toxicological concerns (ref 1).
In this area we develop 2D and 3D models, especially for toxicity to dopaminergic neurons (ref. 2), and we combine neurons with other cell types to generate more complex environments for pharmacological studies of neuro-protectants (ref. 3) and for studying toxicant metabolism and action (ref. 4)
