A biological catalyst for the regeneration of tissues, obtainable directly from an adipose starting material, includes adipose material in liquid solution in a quantity of between 1.0 and 1.5 grams per millilitre of adipose starting material, in which a quantity of between 2 and 30 milligrams of proteins is present, said proteins comprising at least: from 0 to 60 picograms of PDGF, from 300 to 1300 picograms of VEGF, from 10 to 100 picograms of TGFb1, from 3000 to 7500 picograms of FGFb, from 400 to 4000 picograms of IL-1 RA. The biological catalyst is obtained from a method including at least the steps of collecting an adipose starting material; centrifuging the adipose material, to separate the collected material at least into an oily fraction, an aqueous fraction and a cellular fraction; removing the surface oily fraction; collecting the aqueous fraction and the cellular fraction, in which the above-mentioned proteins are found.
