Use of derivatives of exopolysaccharides (EPS) depolymerized sulfated, as cicatrizing

Derivatives polysaccharide low molar mass and sulfated native exopolysaccharides (EPS) native excreted by marine mesophilic bacteria from deep hydrothermal means belonging to the genus Alteromonas or Vibrio for use as healing agents of connective tissue, especially connective tissues dermal and gingival being such derivatives capable of being obtained by the process comprising the following steps: - a step of radical depolymerization of said native EPS, for obtaining derivatives depolymerized low molar, exceeding 100,000 g / mol mass, - a step subsequent sulfation of depolymerized derivatives, possibly freeze-dried, comprising the addition of at least one sulphating agent in an amount sufficient to obtain 10 derived polysaccharide sulfated having a rate of substitution of sulfate groups between 10 and 45% in weight of the total weight of the sulfated polysaccharide derivative, said sulfation step optionally followed by a dialysis step being.
