Description

[Technical field]

[0001] The present invention relates to a composition for promoting hair growth. [Background technology]

[0002] Hair grows and falls out in a certain cycle, and is controlled by various factors secreted from hair papilla cells, outer root sheath cells, etc. Known such factors include hepatocyte growth factor (HGF), vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF), GLI transcription factor, Wnt protein, etc. (Non-Patent Documents 1 and 2).

[0003] Here, Patent Document 1 discloses that taurine extends the hair growth phase and is therefore excellent in promoting hair growth.

[0004] Patent Document 2 discloses that rice extract promotes the production of hepatocyte growth factor and is therefore highly effective in promoting hair growth.

[0005] Patent Document 3 discloses that bamboo shoot extract activates hair papilla cells and promotes the production of vascular endothelial growth factor and fibroblast growth factor, and thus has excellent hair growth promoting effects. [Prior art documents] [Patent documents]

EXAMPLES

[0049] Next, the present invention will be specifically described with reference to examples, but the present invention is not limited to the following examples.

[0050] In order to investigate the effects of pantothenyl ethyl ether, pyridoxine hydrochloride, or tocopherol acetate on hair growth from multiple viewpoints, the following tests were carried out. In the following tests, cells were cultured in a CO2 (5%) incubator.

[0051] The gene expression levels shown as the results of the test examples are corrected values, and in Test Example 1, β-actin (ACTB) was used as the housekeeping gene.

[0052] <Test 1: Evaluation of PGF gene expression> (1) Verification of the effects of pantothenyl ethyl ether Total RNA was extracted from hair papilla cells and the expression level of the PGF gene was analyzed according to the following procedure.

[0053] Human hair dermal papilla cells (HFDPC) (manufactured by Toyobo Co., Ltd.) suspended in DMEM containing 10% FBS were added at 4 × 10 4 The cells were seeded on a collagen-coated 24-well plate at 1.5 cells / well and cultured at 37°C for 48 hours. After confirming by microscopic observation that there were no problems with cell growth, a solution prepared with 0.1% FBS-containing DMEM was added to the cells so that the final concentrations of pantothenyl ethyl ether were 0.03, 0.1, and 0.3 v / v%. After culturing at 37°C for 24 hours, the cells were harvested and the gene expression level of PGF was measured by real-time PCR. Evaluation was performed with n=3. As a control, a sample without pantothenyl ethyl ether was used.

[0054] (2) Verification of the effects of pyridoxine hydrochloride or tocopherol acetate Similarly, PGF gene expression was evaluated using pyridoxine hydrochloride at final concentrations of 0.01, 0.03, or 0.1 w / v%, or tocopherol acetate at final concentrations of 0.01, 0.03 v / v, or 0.1 v / v, instead of pantothenyl ethyl ether.

[0055] These results are shown in Figures 1 to 3. As is clear from Figure 1, it was found that pantothenyl ethyl ether acts on dermal papilla cells and enhances PGF gene expression in a concentration-dependent manner. Similarly, as shown in Figures 2 and 3, it was found that pyridoxine hydrochloride and tocopherol acetate also act on dermal papilla cells and enhance PGF gene expression in a concentration-dependent manner.

[0056] <Test 2: Evaluation using mouse whisker organ culture> Mouse whisker organ culture was performed according to the following procedure: Nine-day-old mice (B6C3F1) were used for evaluation.

[0057] Specifically, first, whisker hair follicles were isolated on the 0th day of organ culture and photographed under a microscope. Then, the hair follicles were cultured in 10% FBS-containing RPMI1640 medium containing 0.3 w / v% pantothenyl ethyl ether, 0.015 w / v% pyridoxine hydrochloride, or 0.024 w / v% tocopherol acetate in a 24-well plate. After 3 days from the start of culture, the hair follicles were photographed again, the whisker length was measured, and the length extended during the 3-day culture was calculated. Evaluation was performed with n=9. As a control, only 10% FBS-containing RPMI1640 medium without any added components was used. The results are shown in Figure 4.

[0058] Similarly, hair follicles were cultured in 10% FBS-RPMI1640 medium containing 0.3 w / v% pantothenyl ethyl ether, 0.015 w / v% pyridoxine hydrochloride, and 0.024 w / v% tocopherol acetate in a 24-well plate, and the length of the hair follicles extended over 3 days of culture was calculated. After 24 hours of organ culture, hair papilla tissue was isolated from the hair follicles, and total RNA was extracted from the hair papilla cells to analyze the expression level of the PGF gene. The results are shown in Figures 5 and 6, respectively.

[0059] As shown in FIG. 4, when pantothenyl ethyl ether, pyridoxine hydrochloride, or tocopherol acetate was used alone, the mouse whisker organ did not elongate significantly.

[0060] On the other hand, when the three components of pantothenyl ethyl ether, pyridoxine hydrochloride, and tocopherol acetate were combined, mouse whisker organs were significantly elongated, as shown in Figure 5. Furthermore, when the three components were administered in combination, PGF gene expression was enhanced in hair papilla cells, as shown in Figure 6.

[0061] These results indicate that the combination of the three components, pantothenyl ethyl ether, pyridoxine hydrochloride, and tocopherol acetate, enhances the production of PGF and promotes hair elongation.

[0062] <Test 3: Evaluation of sulfotransferase (SULT) 1A1 gene expression> (1) Verification of the effects of pantothenyl ethyl ether Total RNA was extracted from human hair follicle keratinocytes and the expression level of the SULT1A1 gene was analyzed according to the following procedure.

[0063] Human hair follicle keratinocytes (HHFK) (ScienCell Research Laboratories, Inc., product number 2440) suspended in keratinocyte medium (ScienCell Research Laboratories, Inc., product number 2101NZ) were added at 5 × 10 4The cells were seeded on a 24-well plate at 1000 cells / well and cultured at 37°C for 48 hours. After confirming that there was no problem with cell growth by microscopic observation, a solution prepared with Defined Keratinocyte-SFM (Thermo Fisher Scientific; product number 10744019) was added to the cells so that the final concentration of pantothenyl ethyl ether was 0.03, 0.1, or 0.3 v / v%. After culturing at 37°C for 24 hours, the cells were collected and the gene expression level of SULT1A1 was measured by real-time PCR. Evaluation was performed with n=3. As a control, a solution without pantothenyl ethyl ether was used. The results are shown in Figure 7.

[0064] (2) Verification of the effects of pyridoxine hydrochloride Similarly, SULT1A1 gene expression was evaluated using pyridoxine hydrochloride at final concentrations of 0.01, 0.03, and 0.1 w / v% instead of pantothenyl ethyl ether. The results are shown in FIG.

[0065] As shown in Figure 7, pantothenyl ethyl ether acts on human hair follicle keratinocytes and enhances SULT1A1 gene expression in a concentration-dependent manner. Similarly, as shown in Figure 8, pyridoxine hydrochloride also acts on human hair follicle keratinocytes and enhances SULT1A1 gene expression in a concentration-dependent manner. These results suggest that pantothenyl ethyl ether and pyridoxine hydrochloride have the effect of promoting the conversion of minoxidil to minoxidil sulfate in vivo.
