Our assays and tests

Some examples of assays and tests on ExAdEx 3D models

ExAdEx R&D ex vivo platform includes some tailored assays and analyses to fit your needs and claims substantiation goals with various techniques ranging from molecular to functional assays, metabolic activity, cell analysis as well as advanced 3D/4D tissue imaging tools for scientific or marketing purposes.

The effect of pharmacological compounds or active principles can be tested on different targets within the same study: Stem Cells, Mature Adipocytes, Extra-cellular Matrix, Vascularisation, Lymphatic network, etc). That’s the power of our ExAdEx models: a multiparametric tool for multiple layers of investigation.

Working in close collaboration with French academics partners and specialized technical platforms, as well as KOLs in adipose tissue biology, we can also develop tailored, on-demand models and new assays for a deeper comprehension of mechanisms of actions on the first 3D human adipose tissue models.
