Title: Innovations by Gérard Raguenes in Tissue Regeneration
Introduction
Gérard Raguenes is a notable inventor based in Locmaria Plouzane, France. He has made significant contributions to the field of tissue regeneration through his innovative research and patents. With a total of three patents to his name, Raguenes has focused on developing novel methods and applications for marine-derived polysaccharides.
Latest Patents
One of Gérard Raguenes' latest patents is titled "Sulfated depolymerized derivatives of exopolysaccharides (EPS) from mesophilic marine bacteria, method for preparing same, and uses thereof in tissue regeneration." This invention pertains to low-molecular weight sulphated polysaccharide derivatives obtained from native exopolysaccharides excreted by mesophilic marine bacteria found in deep hydrothermal environments. The method involves a two-step process: first, free radical depolymerization of the native EPSs, followed by sulphation of the resulting derivatives. These derivatives have been shown to act as effective wound-healing agents, particularly in the preparation of pharmaceutical compositions aimed at treating or preventing diseases affecting connective tissues, such as skin and gum tissues. The research demonstrates that the polysaccharide derivative GY 785 DRS can stimulate fibroblast proliferation in reconstructed connective tissues at a concentration of 10 µg/mL.
