<p>The invention concerns a method for the preparation of an acellular organic tissue of human or animal origin for revitalization, in particular for the introduction of living cells, comprising a stage in which the acellular organic tissue (2; 12) is provided with a plurality of holes (4; 14) made through its surface (8; 18) and extending towards the inside of the tissue (2; 12), wherein the plurality of holes (4; 14) is made by means of one or more needles. The holes (4; 14) intersect partially, thus forming holes (4; 14) partially communicating with each other. The invention also concerns a corresponding acellular organic tissue (2; 12) of human or animal origin prepared for revitalization, in particular for the introduction of living cells, comprising holes (4; 14) that are punctures made with needles and extending from the surface of the tissue (8; 18) towards its inside. The holes (4; 14) intersect at least partially and are therefore holes (4; 14) partially communicating with each other.</p> |
