The object of the invention is essentially a new application connection, which is a copolymer salt of 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid and 2-hydroxyethylphosphonate ether.

More specifically, the present invention relates to the use of this compound as an agent to stimulate and/or accelerate the proliferation and/or differentiation of fibroblasts, in particular for the manufacture of a composition intended to stimulate healing or alternative for the manufacture of a composition intended for use ex vivo to generate cells for skin grafts.

The invention also relates to a bandage for the treatment of wounds containing this compound, alone or in combination with other active ingredients.

It is known that open wounds, including burns, ulcers, neuropathic ulcers, venous or arterial ulcers, diabetic ulcers, decubitus ulcers, bullous lesions, exudative wounds, superficial dermal-epidermal damage, which can be chronic or acute, the vast majority of wounds.

One of the primary goals in the treatment of wounds, regardless of its nature or origin, is the closure of this wound.

In addition, it is known that wound healing is a natural biological phenomenon is s, where human and animal tissue is able to repair localized damage through the process of repair and regeneration, which are specific to it.

In General, wound healing occurs in three phases: phase purification, the phase of granulation and epithelialization phase, where each of these three phases is characterized by specific cellular activities that cause the progression of the process of reparation in accordance with the exact chronological sequence.

Phase purification is characterized by the appearance of early inflammatory events. Immediately after injury begin secretion, originating from blood and lymphatic vessels. Coagulation induced activation of thrombokinase, which is released when it is accompanied by the formation of fibrin. After about 10 minutes starts exudation, which should provide protection against infection and cleansing wounds. About 4 days later, the damage comes in the proliferative phase. The body begins to compensate for the loss of the substance of the new cloth. For this purpose fibroblasts initially produce mucopolysaccharides, which serve as a matrix for the development of collagen fibers of the connective tissue. Between 6-th and 10-th day, on average, starts phase of differentiation. Begins the maturation of collagen fibers. The wound is reduced the od of the influence of special cells, myofibroblasts. Granulation tissue is gradually becoming depleted water and contains fewer vessels, thus becoming stronger. Then it is converted into scar tissue, which, in turn, stimulate the contraction of the scar.

During the second phase of healing, known as the phase of granulation tissue, fibroblasts play an important role. The granulation phase lasts about 3 weeks, and during the normal healing process takes place epithelialization phase. Fibroblasts proliferate in the wound, as well as precursor cells keratinocytes from the wound edges, from hair follicles and sweat glands. After 3 days, fibroblasts produce collagen fibers which are oriented in accordance with the forces to which they are exposed. Their proliferation is controlled by a set of defined factors. As a General rule, this proliferation is stopped when the granulation tissue made up for the loss of substance, and when the proliferation of fibroblasts reached the level of the edges.

The fibroblast is one of the main agents in the healing process. Indeed, about 6 days more than half of fibroblasts present in the wound, converted to myofibroblast. These cells are characterized by the presence in their cytoplasm of the contractile myofibrils, which cause the reduction of the wound and, therefore, slimming the surface area of the wound and accelerate its closing.

These cells, therefore, play an indispensable role in reducing wound, which is the main phenomenon of spontaneous closure in abdominal wound. More than 40% of myofibroblasts (containing contractile protein, smooth muscle actin alpha) are present in the granulation tissue. When the wound heals, these cells die, although the signal that triggers their disappearance, is not fully understood.

The fibroblast is also a key cell proliferative phase. The secretes fibroblast collagen type III, and then the collagen type I and heparan sulfate, which are fundamental components of the dermal extracellular matrix, but also hyaluronic acid, chondroitin sulfate, fibronectin and collagenase, leading through the result to the closure of the wound.

The healing process, even for small wounds or holes, can last for several hours, several days or several weeks or even more in some circumstances, as, for example, in the case of ulceration, where the wound can be kept for much longer periods of time, i.e. months or years.

During this period of healing, if he lasts a short or long time, the wound may be susceptible to infestations of any type (pathogenic organisms or foreign substances) up until regen is the situation of new tissue will not completely close the hole.

To prevent any infection of the wound is usually treated to remove any contaminants (dust, debris, etc.), capable of introduction of pathogenic substances in the area of the damaged region. Consistently conducts the removal of dead tissue in this area and disinfection. In some cases, introducing a certain number of stitches to facilitate wound closure. Once these stages are carried out, the wound support in an environment conducive to healing. To do this, use different types of bandages to prevent the introduction of pathogens and/or their proliferation.

Therefore, in the treatment of wounds, it is important to stimulate the phenomenon of wound closure to prevent, for example, invasion of the wound microorganisms or foreign substances and, consequently, infection of the wound. The need to have funds for the induction or stimulation of the wound-healing process.

For the purpose of inducing or accelerating the healing of wounds you can enter a number of active agents. These active agents may act at different levels and in different phases of healing. They vary according to the stage and type of wound to be treated. These active agents may, for example, be a factor in the growth of fibroblasts and/or keratinocytes (such as the main factor in growing the and fibroblasts) or pseudovector growth (such as mannose-6-phosphate), glycosaminoglycans (such as hyaluronic acid, collagen and so on), hormones such as estradiol, dehydroepiandrosterone, and so on), polysaccharides (such as dextran), etc.

It was discovered, unexpectedly and surprisingly, it is also possible to stimulate and/or accelerate the proliferation and/or differentiation of fibroblasts and, therefore, stimulate healing through connection, which is a copolymer salt of 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid and 2-hydroxyethylphosphonate ether.

Preferably the above-mentioned salt of 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid is a sodium salt.

This copolymer is a product which is in itself known, in particular, in the field of cosmetics due to its emulsifying/stabilizing properties and good thickening ability.

Such a product, for example, sold by SEPPIC under the trade name Sepinov EMT 10®.

Thus, in accordance with the first aspect, the object of the present invention is the use of a copolymer salt of 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid and 2-hydroxyethylphosphonate ester for the manufacture of a composition intended to stimulate and/or accelerate the proliferation of fibroblasts in vivo or ex vivo, and in which lastnosti, for the manufacture of a composition intended to stimulate healing.

The above-mentioned copolymer can be applied in vivo or ex vivo.

As an example of the application of ex vivo may be mentioned the use of this compound for the preparation of culture medium for stimulating the proliferation of fibroblasts. It turns out that this application is useful for autologous skin grafts or skin epidermal layer. This is because with this type of transplant techniques of cell culture used in order to obtain a sufficient surface area of the skin from a small sample taken from the patient or the patient. The use of a copolymer according to the present invention makes it possible to accelerate the proliferation of fibroblasts and, therefore, it appears that it is useful for this type of treatment.

In the context of its application in vivo the above-mentioned copolymer can be applied for the manufacture of a composition, which will enable its direct application to the wound and surrounding area, or even on the mucous membrane, preferably by topical application. Preferably the copolymer include in a bandage.

Typically, the above-mentioned copolymer can be used alone or in combination with other active substances, which provide the ability to induce or is Smriti healing, or which may play a favorable role in the treatment of wounds, such as, for example, antimicrobial agents, or pain relievers. This combination of active agents provides the combined conservative treatment of wounds. Among the active substances that can be applied in the context of the invention, one can mention, as examples, bactericidal or bacteriostatic agents (bleach, chlorhexidine, of silver salts, zinc salts, metronidazole, neomycin etc), agents for stimulating healing (hormones, peptides etc), enzymes to stimulate cleansing of the wound (pepsin, trypsin, and so on), protease inhibitors or metalloproteinase, pain relievers or local anesthetics (lidocaine, cinchocaine) or nonsteroidal anti-inflammatory drugs (ibuprofen, Ketoprofen, fenoprofen, diclofenac).

Preferably the above-mentioned copolymer should be used in combination with the sulfated saccharide or a salt or complex of sulfated saccharide. This sulfated saccharide may, for example, be octasulphate sucrose in the form of a complex or salt with a metal such as Na, K, Ca, SB, Ba, Al, Zn, si, Zr, Ti, Mn, or Os, or with an organic base, such as an amino acid. In particular, preferred results are obtained when the above-mentioned copolymer is used in combination potassium octasulphate sucrose, which is an active ingredient known for its action in the healing process.

Studies of cell proliferation in vitro unexpectedly given the opportunity to show that the copolymer salt of 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid and 2-hydroxyethylphosphonate ester exhibits activity on the proliferation of fibroblasts at a very low dose. Specifically, this activity see, when the copolymer is present in the culture medium at a concentration of 0,00064 mg/ml

Also it is shown that, particularly preferably, the above-mentioned copolymer is also active in several days. Tests conducted in vivo, given the opportunity to detect activity on the proliferation of fibroblasts in 72 hours after the inclusion of the specified copolymer in the culture medium. Particularly preferably, when the copolymer include in a bandage. Specifically, the same bandage can be applied for several days, and at the same time it remains active without the need for its replacement.

Typically, the copolymer used in the context of the present invention may be included in any type of composition, such as, in particular a solution, cream, gel, mass (sludge), in particular elastomeric mass, or bandage. The copolymer may be included in the compress. The term "compress" as meaning any type AB is orbimage material, usually used in dressings, such as, for example, textile materials, which may be an absorbent nonwoven materials (e.g., based on viscose), possibly combined with non-absorbent non-woven materials (such as polyester). It may also include overabsorbed fiber (such as Lanseal® Fibres, commercially available from Toyobo company, Ltd) or polyurethane foam.

In particular, the copolymer may be present in the mass, part of the dressing, or on a separate layer dressings, or as an alternative, the coating covering the surface of the bandage, designed to bring it into contact with the wound for its treatment.

The term "bandage" is here meant to include any type of well-known bands, and preferably the edge of the dressing. These dressings are commercially available, e.g. under the trade names Tulle Gras®(Solvay Pharma), Physiotulle®(Coloplast) or even Urgotul®(Laboratoires Urgo) and described in the patent EP 1143895.

These border dressings, as a rule, are in the form of a sieve or mesh, covered with a mass, usually elastomeric mass. They may also consist of masses without fabric or mesh-shaped layer, which may or may not have through holes depending on the type of wound that dressings (layer, which has through holes, etc is doctitle use on exudative wound, when the mixture has or has weak absorbent ability, holes, thus, enable the evacuation of exudate from the wound).

The present invention also finds application for the manufacture of bandages, based on hydrogels and hydrocolloids, which include the above-mentioned copolymer. Known dressings based on hydrocolloids are commercially available, for example, under the names Algoplaque®(Laboratoires Urgo), Duoderm®(Convatec) and Comfeel®(Coloplast). Such dressings are described in the following patent applications: FR 2392076, FR 2495473 and WO 98/10801 and EP 264299.

The copolymer used in the context of the present invention can be incorporated into the absorbent element, such as a wrap or foam, for example, by depositing it on the surface intended to bring into contact with the wound, as described in patent application WO 2006/007844.

The present invention also finds application for the manufacture of edge dressing in combination with an absorbent layer, such as foam or wrap, or hydrocolloid in combination with absorbent foam. Such dressings are known and are commercially available, e.g. under the trade names UrgotulDuo®and Cellosorb®(Laboratoires Urgo). In such bands the above-mentioned copolymer may be included in the mass and/or the absorbent layer.

Edge dressing, preferably use is Jaimie in the context of the present invention, consist of elastomeric mass, i.e. consisting of one or more than one elastomer selected from block copolymers of styrene-olefin-Sterol, and one or more than one compounds selected from plasticizers, adhesive resins, and optionally antioxidants.

Such elastomeric mass is well known to specialists in the art and described, for example, in the book "Advances in Pressure Sensitive Adhesive Technology", published by Donatas Satas in April 1995 Chapter 7, "Wound dressings", s-171.

When it is incorporated into the dressing, such as the edge of the bandage, the above-mentioned copolymer can be applied at a concentration of from 1% to 5 wt.% relative to the mass of the elastomeric mass. It is shown that this concentration is sufficient to activate fibroblasts and, therefore, to stimulate healing.

Typically, the above-mentioned copolymer should be present in the bandage in number, which can range between 0.1% and 20 wt.% regarding the mass, in which it is included, and preferably between 1% and 5 wt.%.

According to the second aspect of the present invention is coated dressings described above, which includes a copolymer salt of 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid and 2-hydroxyethylphosphonate ether.

To demonstrate the activity of the above-mentioned copolymer in fibroblasts was Prov who were in vitro study, using two types of experiments:

1. Copolymer, alone or in combination with the active substance (in this case potassium sucrose by octasulphate) was added directly to the culture medium of fibroblasts at various concentrations.

In this case, the various cultivation of the copolymer, of one or in combination with potassium sucrose by octasulphate thus prepared was added to the culture medium.

Breeding copolymer Sepinov EMT 10 at 0.011 mg/ml and potassium sucrose octasulphate when 0,00064 mg/ml, therefore, tested in culture medium containing fibroblasts.

2. Copolymer, alone or in combination with the active substance (in this case potassium sucrose by octasulphate) included in the matrix edge of the bandage, and then the bandage was applied to the culture wells containing fibroblasts.

In this case, the various border dressings containing copolymer at various concentrations, in combination or not in combination with potassium sucrose by octasulphate were made in accordance with the method described below. Edge dressing that does not contain neither of these two active agents, was also fabricated and tested for comparison.
