Definitions
- the present invention relates to a synthetic polysulfated oligosaccharide having 1 to 4 ose units, its salts, or its complexes, for its use to activate the epidermis, in particular during the healing of wounds.
- Wound healing is a natural biological phenomenon, with mammalian tissue capable of repairing localized lesions through their own repair and regeneration processes.
- the speed and quality of wound healing depend on the general condition of the affected organism, the etiology of the wound, the condition and location of the wound, and whether or not it occurs. infection, as well as genetic factors that may or may not predispose to healing disorders.
- the natural healing of a wound occurs mainly in three successive phases, each of these phases being characterized by specific cellular activities that advance the repair process according to precise chronological phases: the inflammatory phase, the granulation phase (or phase proliferative) including in particular the epidermization step, and the ripening phase.
- the second phase, the proliferative phase thus comprises two stages.
- the first step corresponds to the development of the granulation tissue while the second step corresponds to the actual epidermization step.
- the granulation phase allows the establishment of a transient tissue that will fill the loss of substance resulting from the aggression at the origin of the wound. This transient tissue is called "granulation tissue".
- the latter consists of:
- Neovascular vessels from the peripheral vessels to the lesional focus, there will be a multiplication and then a migration of endothelial cells, first of all in the form of solid cords which are secondarily hollowed out by vascular lumen leading to the reconstitution of new vessels.
- Fibroblasts - myofibroblasts synthesizing collagen and the other elements of the extracellular matrix accompany the neovessels, elaborate a new provisional conjunctive matrix; it is first of all slender, fragile, rich in fibronectin and hyaluronic acid; it carries out a scaffolding allowing the migration of other fibroblasts and neo vessels then forming the connective tissue constituting the dermis.
- this colonization of the wound continues at the higher level by proliferation of keratinocytes above this granulation tissue.
- cutaneous stem cells surrounding the injured area migrate and proliferate to compensate for cell loss and cover the exposed area. This phenomenon takes place in different stages: detachment of the cells from the dermal-epidermal junction; hypertrophy of cells; proliferation and migration of said cells along said dermo-epidermal junction until contact of cells from the opposite bank (contact inhibition); Finally, the cells differentiate and stratify to reconstitute a complete and functional epidermis, this is called the epidermization step.
- wounds include chronic wounds such as venous ulcers, sores or wounds characteristic of diabetic subjects.
- Chronic wounds are defined by a lack of healing after a delay of 6 weeks from the onset of the wound regardless of the treatment applied. To treat this type of wounds, it may be crucial to accelerate the healing process at any of these steps, and particularly at the level of the epidermization step.
- a synthetic polysulphated oligosaccharide having 1 to 4 ose units, and more particularly the potassium salt of sucrose octasulfate makes it possible to increase the rate of cicatrization, by activating the epidermalization, and more particularly the proliferation and migration of keratinocytes at the level of the epidermis.
- the subject of the invention is therefore a synthetic polysulfated oligosaccharide having 1 to 4 ose units, its salts, or its complexes, for its use for activating epidermization, in particular for activating epidermization during wound healing.
- activate epidermization any positive stimulation of the migration, proliferation and / or stratification of keratinocytes at the level of an injured skin epidermis, so as to increase the speed of healing, resulting in accelerated wound closure.
- acceleration epidermization means any increase in the rate of migration and proliferation of keratinocytes at the level of an injured skin epidermis resulting in accelerated wound closure.
