Abstract[English]
The invention relates to methods of manufacturing a three dimensional osteochondral tissue by Laser Induced Forward Transfer (LIFT) laser printing, comprising the steps of providing a donor bio-ink comprising aggregates of cartilage and/or bone forming cells, transferring cell aggregates to a receiver substrate into a patterned layer of cell aggregates by pulsed laser energy focused on the bio ink, and repeating steps a) and b) to obtain further patterned layers of aggregates on previously deposited layers.[French]
L'invention concerne des procédés de fabrication d'un tissu ostéochondral tridimensionnel par impression laser LIFT (Laser Induced Forward Transfer), comprenant les étapes suivantes : mise à disposition d'une bio-encre donneuse constituée d'agrégats de cellules cartilagineuses et/ou osseuses, transfert des agrégats cellulaires sur un substrat récepteur en une couche à motifs d'agrégats cellulaires par une énergie laser pulsée concentrée sur la bio-encre, et répétition des étapes a) et b) pour obtenir d'autres couches à motifs d'agrégats sur les couches précédemment déposées.
