The present invention relate to three dimensional porous polysaccharide matrices able to induce mineralization of a tissue in osseous site, as well as in non-osseous site, in the absence of stem cells or growth factors.

Porous polysaccharide scaffold comprising nano-hydroxyapatite and use for bone formation

The present invention relate to three dimensional porous polysaccharide matrices able to induce mineralisation of a tissue in osseous site, as well as in non-osseous site, in the absence of stent cells or growth factors.

Bioprinting station () comprising:&#x2014;a Bioprinting device () adapted to deposit a pattern of biological material () onto an area of interest () of a substrate (),&#x2014;an imaging system () adapted to acquire an image of the substrate () and to reveal on the acquired image the area of interest () with respect to a remaining part () of the substrate (), the acquired image of the substrate () being processed so as to detect the revealed area of interest () on the acquired image and to determine the pattern corresponding to the area of interest () detected on the acquired image.

Bioprinting station, assembly comprising such bioprinting station and bioprinting method

The present invention provides a method of extracting organic substances present in coral, which consists in treating the coral with a fluid or a mixture of fluids in the supercritical state without modifying the crystalline structure of said coral, at a temperature of less than 270&#xb0; C. and at a pressure which is much higher than the critical pressure of said fluid or mixture of fluids, for example of the order of at least 3 times, and preferably at least 5 times said critical pressure. It also provides coral obtained by said method and bone substitutes fabricated from said coral.
