Abstract

Abstract Translated from French L'invention concerne un procédé d'obtention d'un équivalent de peau et l'équivalent de peau correspondant (27). Selon ce procédé, on prépare un équivalent de derme (24) en mélangeant des cellules contractiles , un milieu nutritif et du collagène pour former un gel qui se contracte ; on utilise cet équivalent de derme (24) comme substrat pour un équivalent d'épiderme (26) obtenu par ensemencement avec les kératinocytes d'un explant animal ou humain. Selon l'invention, on ensemence le substrat (24) au moyen d'au moins un tronçon de follicule pileux (22) comportant au moins partiellement sa gaine cellulaire, ledit tronçon étant implanté sensiblement perpendiculairement à la surface libre du substrat. The invention relates to a method for obtaining a skin equivalent and the corresponding skin equivalent (27). According to this process, a dermis equivalent (24) is prepared by mixing contractile cells, a nutritive medium and collagen to form a contracted gel; this dermis equivalent (24) is used as substrate for an epidermis equivalent (26) obtained by seeding with the keratinocytes of an animal or human explant. According to the invention, the substrate (24) is seeded by means of at least one section of hair follicle (22) at least partially comprising its cell sheath, said section being located substantially perpendicular to the free surface of the substrate.
