• the principle of this test is to study cell migration to the well center of the 96-well plate. It consists in placing a stopper in wells, to create a detection zone of 2 mm in diameter.

Plates without stoppers and with active ingredients are incubated at 37 ° C for 24 hours in DMEM 0% FCS.

• the percentage of activity relative to TGFp is calculated by:
• TGFP at 5 ng / ml induces the migration of the keratinocytes in a reproducible manner
