(FR) ÉCHAFAUDAGE BIOLOGIQUE ET SA MÉTHODE DE FABRICATION
Abstract
(EN)
A biological scaffold in the present invention comprises a main body, a biological material layer, and an optional tissue adhesive layer. The main body at least has a non-constituted collagen matrix. The biological material layer is coated at least on a surface of the main body, and the tissue adhesive layer is disposed at least on another surface of the main body. When the biological scaffold is adhered to a tissue through the tissue adhesive layer, a plurality of cells move from the tissue to either the adhesive layer or the biological material layer for tissue repairing or regeneration.
(FR)
Un échafaudage biologique dans la présente invention comprend un corps principal, une couche de matériau biologique et une couche adhésive tissulaire facultative. Le corps principal a au moins une matrice de collagène non constituée. La couche de matériau biologique est revêtue au moins sur une surface du corps principal, et la couche adhésive tissulaire est disposée au moins sur une autre surface du corps principal. Lorsque l'échafaudage biologique est collé à un tissu par la couche adhésive tissulaire, une pluralité de cellules se déplacent du tissu à la couche adhésive ou à la couche de matériau biologique pour la réparation ou la régénération tissulaire.
