Abstract: The present invention relates to a platelet lysate foam obtained from blood derivative (allogenic or autologous) which retains the biological properties of the platelet lysate and has optimal properties, in particular mechanical but also storage, which allow sale thereof and make handling thereof easier. The present invention also relates to the use of a platelet lysate foam for therapeutic purposes, cell culture and cell therapy. The present invention also relates to a process for getting a platelet lysate foam by a process of drying in a supercritical CO2 atmosphere.

Abstract: The present invention relates to a porous biomaterials surface activation method by coating with a layer of apatitic nanocrystals in order to increase their surface reactivity. The method according to the invention is characterized by the following steps: a) preparing a nanocrystalline apatitic calcium phosphate analogous to bone mineral by mixing a calcium salt solution with a phosphate salt solution in a Ca/P ratio ranging between 1.3 and 2 at a temperature ranging between 0 and 60 ° C., b) slurrying the mixture obtained in step a) in an aqueous solution so as to obtain a fluid, homogeneous paste containing 80 to 98% of water, c) bringing a porous biomaterial into contact with the suspension obtained in step b), d) drying the porous biomaterial at a temperature below 100 ° C.
