Abstract
The invention relates to a method for preparing a polymer scaffold that comprises the steps of providing a piece of a fabric of filaments of a first biodegradable or biocompatible polymer, applying a coating of a second polymer to said arrangement of filaments, and stretching the piece along its axis of longitudinal extension, thereby obtaining an aligned microfibrillar scaffold. The invention further relates to a method for providing an artificial tissue, and to a microfibrillar scaffold of aligned filaments obtained by the method of the invention.
