Our assays and tests

Some examples of assays and tests on 3D ExAdEx tissue models

ExAdEx’s R&D ex vivo platform offers customizable assays and analytical services to meet the specific needs of our partners. Our comprehensive suite of techniques spans molecular, functional, and metabolic activity assays, as well as advanced cell-based analysis and state-of-the-art 3D/4D tissue imaging systems for both scientific and commercial applications.

Our platform enables the testing of pharmacological compounds or active principles across multiple targets within a single study, including stem cells, mature adipocytes, extracellular matrix, vascularization, and lymphatic networks, among others. This multiparametric capability makes ExAdEx models ideal for multi-layered investigations and high-content analysis.

In collaboration with leading French academic partners, specialized technical platforms, and key opinion leaders (KOLs) in adipose tissue biology, we also offer the development of bespoke, on-demand models and assays. These innovative approaches allow for a deeper understanding of mechanisms of action within our pioneering 3D donor-derived native adipose tissue models.
