In vitro and ex vivo assays for drug targeting obesity/type 2 diabetes and NASH/MASH
To limit the use of animals and support our customers combatting obesity/type 2 diabetes and NASH/MASH.
Physiogenex offers its experience/expertise and a panel of in vitro and ex vivo services.
Optimize and expedite your preclinical drug development programs with our validated systems of adipocytes (human and rodent), muscle (rodent), hepatocyte steatosis model (HepaRG, monolayer), 3D NASH model (human hepatocytes, Kupffer cells and Stellate cells in spheroids culture).
