Description

DESCRIPTION OF DRAWINGS

[0016] FIG. 1 is photographs illustrating changes in hair with the passage of time after treating a patient with alopecia using a hair growth-promoting composition according to an exemplary embodiment of the present invention.

BEST MODE

[0017] Hereinafter, a hair growth-promoting composition according to an exemplary embodiment in the present disclosure will be described in detail.

[0018] The hair growth-promoting composition contains a stem cell culture solution obtained from a culture medium of mesenchymal stem cells which have been subcultured two or more times. The stem cell culture solution contains metabolites formed during culturing the stem cells in addition to the culture medium containing various additives.

[0019] In detail, a process of obtaining the stem cell culture solution may include: (a) culturing the mesenchymal stem cells; (b) collecting the mesenchymal stem cells which have been subcultured two or more times and three-dimensionally culturing the collected mesenchymal stem cells together with a biocompatible scaffold in a serum-free medium; and (c) collecting a culture medium.

[0020] Here, in (a) the culturing of the mesenchymal stem cells, it is preferable that the mesenchymal stem cells are cultured in a matrix medium and an expansion medium and then subcultured, and in (b) the three-dimensionally culturing the mesenchymal stem cells, it is preferable to obtain the stem cell culture solution at least three times while changing the medium every 3 days. Further, at least one of basic fibroblast growth factor (bFGF) and epidermal growth factor (EGF) may be added to the serum-free medium to perform the culturing.

[0021] In addition, the biocompatible scaffold, which is a cell support having a cell adhesive surface, may be a natural or synthetic polymer. Examples of the biocompatible scaffold include alginate, proteins, collagen, fibrin, hyaluronic acid, cellulose, poly(alpha-hydroxy acid) based polymers, poly(vinyl alcohol), polyanhydride, and the like.

[0022] A mesenchymal stem cell culture solution composition according to the present invention for achieving another object of the present invention is prepared by the method described above, such that the mesenchymal stem cell culture solution composition contains large amounts of growth factors and cytokines, and particularly contains high contents of VEGF and EGF. Preferably, contents of VEGF and EGF contained in the mesenchymal stem cell culture solution composition according to the present invention are equal to or higher than 4 times a content of VEGF and 17 times a content of EGG in a culture solution composition according to the related art, respectively.

[0023] The hair growth-promoting composition according to the present invention contains the stem cell culture solution containing large amounts of bioactive materials obtained by effectively culturing the mesenchymal stem cells in the serum-free medium as an ingredient. The mesenchymal stem cells used in the culturing may be obtained from the bone marrow, the cord blood, the adipose tissue, or the like. Particularly, adipose-derived stem cells have advantages in that it is relatively easy to approach the adipose-derived stem cells, the adipose-derivative stem cells may be simply collected, and a large amount of the adipose-derivative stem cells may be obtained from an individual.

[0024] According to the present invention, a large amount of mesenchymal stem cells may be effectively obtained within a short time by suitably using the matrix medium and the expansion medium in the culturing the mesenchymal stem cells. Further, in the method according to the present invention, the cells may be stably maintained for a long period of time by performing three-dimensional culturing using the biocompatible scaffold in the serum-free medium during a process of obtaining the culture solution, thereby making it possible to produce a large amount of cell culture solution. As described above, the stem cell culture solution produced by the method according to the present invention is characterized in that contents of the growth factors such as VEGF and EGF are significantly high as compared to a culture solution produced by two-dimensional culturing, which is a cell culturing method according to the related art. Since the mesenchymal stem cells are obtained from the human bone marrow, adipose tissue, cord blood, or the like, an amount of the human bone marrow, adipose tissue, cord blood, or the like, capable of being collected is small, and thus, the mesenchymal stem cells obtained from the above-mentioned tissue is also restricted. In order to use the stem cell culture solution for clinical purpose, it is preferable that a large amount of stem cell culture solution is obtained from a restrictive number of cells and contents of bioactive materials contained in the culture solution are high.

[0025] Generally, in order to culture and maintain mesenchymal stem cells, bovine-derived serum is required, but in order to use a cell culture solution for clinical purpose, it is preferable that the bovine-derived serum is not contained in the culture solution. In the case in which the bovine-derived serum is not contained in the culture medium of the mesenchymal stem cells, it is difficult to stably maintain the cells.

[0026] The present invention provides a method capable of stably culturing the mesenchymal stem cells in the serum-free medium in which the bovine-derived serum is not contained. The culture solution obtained by the method as described above contains significantly high contents of the growth factors as compared to a culture solution produced by an existing method. For example, a content of vascular endothelial growth factor (VEGF) contained in the stem cell culture solution obtained by the culturing method according to the present invention is increased by about 4 times as compared to the culturing method according to the related art, such that the stem cell culture solution may provide a significantly improved effect, and thus, the stem cell culture solution may be significantly utilized in view of clinical application.

[0027] In the case of three-dimensionally culturing stem cells together with a biocompatible scaffold such as fibrin glue according to the method in the present invention, since the stem cells may be cultured in a bottle having a simple shape without using a plate generally used for culturing cells, economical efficiency is significantly high, and a large amount of culture solution may be easily obtained. Further, in the two-dimensional culturing, since the number of cells is restricted depending on a size of a cell culture surface, contents of bioactive materials secreted from the stem cells are also restricted, but in the case of performing the three-dimensional culturing according to the present invention, since it is possible to adjust the number of cells, it is possible to increase concentrations of the bioactive materials in the culture solution if necessary.

[0028] Generally, in the case of plate-culturing the mesenchymal stem cells in the serum-free medium, the mesenchymal stem cells are not stably maintained, but are detached from the cell culture surface to die. According to the present invention, the mesenchymal stem cells having a property of attaching to something to grow may be stably maintained in a three-dimensional scaffold by culturing the mesenchymal stem cells together with the biocompatible scaffold. In the case of using fibrin glue as an example of the biocompatible scaffold, a survival rate of the mesenchymal stem cells was at least 80% for 14 days, and a high content of VEGF was continuously secreted as compared to the two-dimensional culturing.

[0029] Further, with the method according to the present invention, stability of the cells and the contents of the growth factors secreted in the culture solution may be increased in the case of adding basic fibroblast growth factor (bFGF) and/or epidermal growth factor (EGF) to the serum-free medium to performing the culturing.

[0030] In the present specification, the term “mesenchymal stem cells” means cells capable of having self-proliferation ability and multipotency and expressing cell phenotypes of CD73+, CD90+, CD105+, CD14−, CD20−, CD34−, and CD45−, and the mesenchymal stem cells may be isolated from the bone marrow, the adipose tissue, the cord blood, or the like, but are not limited thereto. However, in a quantitative point of view of the active ingredients of the culture solution, adipose-derived stem cells may be preferable.

[0031] In the present specification, the term “bioactive material” collectively means cytokines, cell growth factors, and the like, which may affect functions of cells or human bodies. The term “stem cell culture solution” means a cell culture supernatant obtained by culturing the stem cells. The stem cell culture solution contains various bioactive materials secreted from the cells during the process of culturing the stem cells.

[0032] The term “biocompatible scaffold” means a support which may have an affinity to cells and be made of a material having a “cell adhesive surface” and to which cells may be three-dimensionally attached and cultured. An example of a nature-derived support may include alginate, proteins, collagen, fibrin, hyaluronic acid, cellulose, or the like, but is not limited thereto. An example of a synthetic polymer may include poly(alpha-hydroxy acid) based polymer, poly(vinyl alcohol), polyanhydride, or the like, but is not limited thereto.

[0033] In the present invention, the three-dimensional culturing may be performed using the biocompatible scaffold such as fibrin glue. With the method according to the present invention, contents of human-derived growth factors, particularly, VEGF and EGF may be significantly increased by three-dimensionally culturing the mesenchymal stem cells together with fibrin glue at the time of culturing the mesenchymal stem cells in the serum-free medium. That is, in the two-dimensional culturing, there is a limitation in increasing the contents of VEGF, and the like, contained in the culture solution even under a hypoxic condition, and the stem cell culture solution may be obtained only once. However, in the three-dimensional culturing, since the stem cells are stably maintained and continuously secret high concentrations of the cell growth factors, it is possible to obtain the culture medium at least three times while changing the culture medium every three days. Further, with the three-dimensional culturing method according to the present invention, since the culturing may be performed in a bottle unlike the plate culturing according to the related art, the stem cell culture solution is possible.

[0034] The mesenchymal stem cells may be cultured through the following processes, and a medium used for culturing the cells is not limited thereto.

[0035] (1) Culturing of Mesenchymal Stem Cells

[0036] After suspending mesenchymal stem cells obtained from the corresponding tissue in a matrix medium and inoculating the suspended mesenchymal stem cells into a culture vessel in a concentration of 10,000 to 40,000 cells/cm.sup.2, the mesenchymal stem cells were cultured. The matrix medium was Dulbecco's modified eagle medium (DMEM) or Dulbecco's modified eagle medium/Ham's F-12 nutrient broth (DMEM/F12) medium containing bovine serum, and the culturing was performed for about 24 hours.

[0037] (2) Culturing in Expansion Media

[0038] After removing the matrix medium, the cultured mesenchymal stem cells were cultured in an expansion medium to proliferate adherent cells. The expansion medium was a DMEM or DMEM/F12 medium containing bovine serum (10%), epidermal growth factor (EGF, 0.1˜100 ng/ml), and/or basic fibroblast growth factor (bFGF, 0.1˜100 ng/ml) and served to rapidly proliferate the adherent mesenchymal stem cells to increase an amount of cells within a short time on a large scale.

[0039] (3) Sub-Culturing

[0040] When cells occupied 80 to 90% of a bottom of the culture vessel, the expansion medium was removed, and the cells were detached from the culture vessel by trypsin treatment. For subculturing, the cells were diluted at 1:3 to 1:4, and the diluted cells were cultured together with the expansion medium in a novel culture vessel. Additional subculturing may be performed by the above-mentioned method.

[0041] (4) Culturing with Biocompatible Scaffold

[0042] The cultured cells were washed with phosphate-buffered saline (PBS) three times or more to remove fetal bovine serum (FBS), and the resultant cells were cultured in a serum-free medium in a state in which the cells were attached to a biocompatible scaffold. Since cell culturing in the scaffold does not require a general cell culture vessel, the cells may be cultured in a sterilized bottle or culture bag on a large scale, which has an advantage in that the cells may be conveniently cultured with a lower cost.

[0043] The stem cell culture solution may contain vascular endothelial growth factor (VEGF), hepatocyte growth factor (HGF), fibroblast growth factor (FGF), transforming growth factor beta1 (TFG-β1), and epidermal growth factor (EGF) as growth factors, and contain collagen, fibronectin, laminin, and hyaluronic acid as extracellular matrix proteins.

[0044] The hair growth-promoting composition may contain 0.001 to 0.1 parts by weight of zinc based on 100 parts by weight of the stem cell culture solution. Further, the hair growth-promoting composition may contain 5 to 50 parts by weight of a panthenol based compound based on 100 parts by weight of the stem cell culture solution. As an example of the panthenol based compound, there is D-panthenol, or the like, and other panthenol derivatives, or the like, may be used.

[0045] The hair growth-promoting composition may contain 0.0001 to 0.1 parts by weight of a water-soluble vitamin based on 100 parts by weight of the stem cell culture solution. As the water-soluble vitamin, D-biotin, or the like, may be used, and other water-soluble vitamins in various forms may be additionally used.

[0046] Each of the ingredients, that is, zinc, the panthenol based compound, the water-soluble vitamin, and the like, are mixed with the stem cell culture solution in an aqueous solution state. As a result, the hair growth-promoting composition contains an aqueous solvent, and 100 to 300 parts by weight of the aqueous solvent may be contained based on 100 parts by weigh to the stem cell culture solution. As the aqueous solvent, a water ingredient such as a saline solution, or the like, is preferable.

[0047] The hair growth-promoting composition may exhibit a hair growth effect only by nebulizing or spraying the hair growth-promoting composition on the scalp or uniformly applying the hair growth-promoting composition on the scalp. That is, since there is no need to administer the hair growth-promoting composition to the scalp by injection, alopecia treatment may be simplified.

[0048] Hereinafter, results obtained by performing a test for proving the hair growth effect of the hair growth-promoting composition according to the exemplary embodiment of the present invention will be described.

Example: Preparation of Hair Growth-Promoting Composition for Test

[0049] A hair growth-promoting composition having the ingredient composition illustrated in the following Table 1 was prepared.

TABLE-US-00001 TABLE 1 Ingredient Stem Cell Culture Zn Aqueous solution Solution D-Panthenol D-biotin Volume 2 cc 1 cc (1 mg) 1 cc (250 mg) 1 cc (0.12 mg)

[0050] Evaluation of Hair Growth Property of Hair Growth-Promoting Composition for Test

[0051] FIG. 1 is photographs illustrating changes in hair with the passage of time after treating a patient with alopecia using a hair growth-promoting composition according to an exemplary embodiment of the present invention.

[0052] A target patient was treated with the hair growth-promoting composition prepared in the Example described above once a week by spraying 7 cc of the hair growth-promoting composition.

[0053] Referring to FIG. 1, it may be confirmed that with the passage of time, hair growth clearly occurred as compared to a state before treatment. Particularly, it was confirmed that effective hair growth may occur by treatment only for 2 months. The effect may be somewhat changed depending on a type of patient with alopecia, but it was judged that excellent effect and efficacy of the hair growth-promoting composition was sufficiently confirmed.
