Les deux organisations appliqueront la biologie du cheveu et la bio-impression pour explorer cette possibilit\u00e9. Si elles y parviennent, il s'agira d'une v\u00e9ritable solution pour les millions de personnes qui souffrent de la perte de cheveux. Rien qu'en Grande-Bretagne, plus de huit millions de femmes en souffrent. Le march\u00e9 propose de nombreux produits qui promettent de r\u00e9veiller les follicules pileux endormis, mais il n'existe pas de rem\u00e8de d\u00e9finitif.<\/p>\n<p>Au c\u0153ur du partenariat entre L'Or\u00e9al et Pioetis se trouve la technologie de bio-impression 3D assist\u00e9e par laser de la biotech, qui dessine des bioinks et les scanne \u00e0 l'aide de faisceaux laser pour une plus grande pr\u00e9cision. L'impression 3D de Pioetis peut atteindre une r\u00e9solution cellulaire de dix microns, ce qui est \u00e9tonnant compte tenu du niveau de complexit\u00e9 de la fabrication. La biotechnologie permet \u00e9galement d'obtenir des taux de viabilit\u00e9 cellulaire allant jusqu'\u00e0 95%. Apr\u00e8s l'impression 3D, il faut compter environ trois semaines de maturation avant de pouvoir tester les tissus.<\/p>\n<p>Fabien Guillemot, PDG et directeur scientifique de Poietis, note que la compr\u00e9hension de la structure et du fonctionnement des cellules du follicule permet aux chercheurs de mieux comprendre ce dont elles ont besoin pour rester en bonne sant\u00e9 et donc pr\u00e9venir l'amincissement et la chute des cheveux. Il ajoute que la technologie de bio-impression assist\u00e9e par laser a la capacit\u00e9 unique d'imprimer des cellules une par une dans la plus haute r\u00e9solution. Elle fonctionne essentiellement comme une imprimante 3D \u00e0 jet d'encre et cr\u00e9e une superposition complexe de micro-gouttes de cellules sur une surface. Le temps rend ce concept tout \u00e0 fait r\u00e9volutionnaire. Dans un d\u00e9lai pr\u00e9cis, les cellules peuvent se transformer en follicules pileux pleinement fonctionnels.<\/p>\n<p>L'Or\u00e9al imprime de la peau humaine en 3D dans ses laboratoires pour tester ses produits de soin et de maquillage. Il est donc logique que la m\u00eame technologie soit appliqu\u00e9e aux soins capillaires. Toutefois, les follicules pileux sont beaucoup plus complexes et le processus prendra donc du temps.<\/p>\n<p>Cr\u00e9dit photo : 3ders<\/p>\n<p><a href=\"http:\/\/www.bbc.com\/news\/technology-37484835\">Source<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>French cosmetic giant L\u2019Oreal and biotech firm Pioetis have signed an agreement to research on the viability of bio-printing a hair follicle, the small organ that produces hair.
