Abstract
The subject matter of the present invention is a device for guiding cell migration comprising a substrate having a textured surface intended to be brought into contact with cells, said textured surface having an anisotropic three-dimensional structure consisting of a network of projections inclined relative to the normal to the plane formed by said textured structure, in the direction imparted by said anisotropic structure.The invention also concerns, according to another aspect, a method for guiding cell migration including the bringing into contact of cells with a substrate having a textured surface and an anisotropic three-dimensional structure, said structure consisting of projections inclined as previously described.The device or method according to the invention can in particular be applied in the fields of dermatology, implantology and tissue engineering.
