The agent according to the present invention contains a horse placenta hydrolyzate as an active ingredient, and is selected from the group consisting of (a) mitochondrial activator, (b) type I collagen production promoter and (c) wound healing agent 1 or Two or more agents.

本発明において用いられるプラセンタは、ウマプラセンタ(ウマ由来のプラセンタ)である。ウマはブタやウシなどと比較して体温が5〜6℃高いため寄生虫の心配がないばかりか、奇蹄類に分類されるウマは、狂牛病(牛海綿状脳症)や***などの偶蹄類に発症する病気にかからない。また、ウシのように反芻をしないウマの内臓は清潔でデリケートなため、添加物やホルモンを受けつけず、他の家畜のように薬物を多用できないうえに、ウマは抗原度が非常に低くアレルゲンになりにくいとされている点でブタ由来のプラセンタやウシ由来のプラセンタよりも優れている。 本発明において用いるウマプラセンタは、ウマの胎盤であれば特に限定されないが、粉砕品(ミンチ品)であると扱いやすく、好適である。また、ウマプラセンタには、血液やその他の部位が付着あるいは混在していることが考えられるため、あらかじめ洗浄などがされているものが好ましい。 The placenta used in the present invention is equine placenta (placenta derived from horse). Horses do not have to worry about parasites because their body temperature is 5 to 6 degrees Celsius higher than that of pigs and cows. Horses that are classified as Perissodactyla include mad cow disease (bovine spongiform encephalopathy) and foot-and-mouth disease. Not affected by the disease that occurs in artiodactyla. In addition, since the internal organs of horses that do not ruminate like cows are clean and delicate, they do not accept additives and hormones, they cannot use drugs as often as other livestock, and horses have a very low antigenicity and become an allergen. It is superior to porcine-derived placenta and bovine-derived placenta in that it is said to be difficult to become. The horse placenta used in the present invention is not particularly limited as long as it is a placenta of a horse, but a crushed product (minced product) is preferable because it is easy to handle. Further, since it is considered that blood or other parts are attached or mixed in the horse placenta, it is preferable that the placenta has been washed in advance.

本発明において、ウマプラセンタの加水分解に用いられる酵素は、プロテアーゼであれば特に限定されないが、システインプロテアーゼ(システインエンドペプチダーゼ)が好適であり、果実由来のシステインプロテアーゼがより好適である。そのようなプロテアーゼとしては、例えば、パパイン、キモパパイン、アスクレパイン、ブロメライン(ブロメリン)、ジンギパイン(ジンギバイン)、フィカイン(ファカイン、フィシン)、アクチニダイン(アクチニジン)、ジアリールヘプタノイド代謝産物(生ウコン由来のクルクミン)などを挙げることができる。 In the present invention, the enzyme used for hydrolysis of horse placenta is not particularly limited as long as it is a protease, but cysteine protease (cysteine endopeptidase) is preferable, and fruit-derived cysteine protease is more preferable. Examples of such proteases include papain, chymopapain, asclepain, bromelain (bromelin), zingipain (zingibain), ficaine (facaine, ficin), actinidyne (actinidine), diarylheptanoid metabolites (curcumin derived from raw turmeric). And so on.

本発明に係る剤は、細胞のミトコンドリアを活性化する作用を有する。すなわち、本発明に係る剤はミトコンドリア活性化剤である。当該細胞は、哺乳動物の細胞であれば特に限定されないが、ヒト細胞が好適であり、ヒト線維芽細胞がより好適である。また、細胞のミトコンドリアが活性化されているか否かを検出するための手法は、特に限定されず、当業者によって適宜選択可能な手法を用いることができる。本明細書実施例においては、ローダミンを用いた細胞染色および蛍光強度値の測定により検出している。 The agent according to the present invention has an action of activating cell mitochondria. That is, the agent according to the present invention is a mitochondrial activator. The cells are not particularly limited as long as they are mammalian cells, but human cells are preferable, and human fibroblasts are more preferable. Further, the method for detecting whether or not the mitochondria of cells are activated is not particularly limited, and a method that can be appropriately selected by those skilled in the art can be used. In the examples of the present specification, detection is performed by cell staining using rhodamine and measurement of fluorescence intensity value.

また、本発明に係る剤は、細胞におけるI型コラーゲンの産生を促進する作用を有する。すなわち、本発明に係る剤はI型コラーゲン産生促進剤である。細胞におけるI型コラーゲンの産生が促進されているか否かを検出するための手法は、特に限定されず、当業者によって適宜選択可能な手法を用いることができる。本明細書実施例においては、エライザによる測定により検出している。 Further, the agent according to the present invention has an action of promoting the production of type I collagen in cells. That is, the agent according to the present invention is a type I collagen production promoter. The method for detecting whether or not the production of type I collagen in cells is promoted is not particularly limited, and a method that can be appropriately selected by those skilled in the art can be used. In the examples of the present specification, detection is performed by measurement with an ELISA.

さらに、本発明に係る剤は、細胞組織の創傷治癒する作用を有する。すなわち、本発明に係る剤は創傷治癒剤である。上述の通り、従来、プラセンタエキス(プラセンタ抽出物)が含むことが知られているEGF(上皮細胞増殖因子)、HGF(肝細胞増殖因子)、FGF(線維芽細胞増殖因子)などの成長因子は、タンパク質であるがゆえに、加水分解反応により分解・失活してしまうため、本発明に係る創傷治癒剤は、従来のプラセンタエキス(プラセンタ抽出物)の奏する創傷治癒効果とは異なるといえる。細胞における創傷治癒効果を確認するための手法は、特に限定されず、当業者によって適宜選択可能な手法を用いることができる。本明細書実施例においては、スクラッチ法による細胞遊走試験により確認している。 Furthermore, the agent according to the present invention has an action of healing wounds of cell tissues. That is, the agent according to the present invention is a wound healing agent. As described above, growth factors such as EGF (epithelial cell growth factor), HGF (hepatocyte growth factor), FGF (fibroblast growth factor), which are conventionally known to contain placenta extract (placenta extract), Since it is a protein, it is degraded and inactivated by a hydrolysis reaction, so it can be said that the wound healing agent according to the present invention is different from the wound healing effect exhibited by the conventional placenta extract (placenta extract). The method for confirming the wound healing effect on cells is not particularly limited, and a method that can be appropriately selected by those skilled in the art can be used. In the examples of the present specification, confirmation was made by a cell migration test by the scratch method.

また、本発明におけるウマプラセンタ加水分解物は、構成成分としてペプチドを最も多く含有する加水分解物であることが、後述する実施例より明らかとなっている。また、本発明におけるウマプラセンタ加水分解物は、構成成分として1,000以上3,000未満の分子量を有するペプチドを最も多く含有することが、後述する実施例より明らかとなっている。なお、本発明において、「構成成分としてペプチドを最も多く含有する」とは、構成する成分の全重量を基準として(構成する成分の重量%を基準として)、ペプチドを最も多く含有することを意味し、「構成成分としてペプチドを最も多く含有する」は、「(ウマプラセンタ加水分解物において)構成成分としてのペプチドが最大組成比率の第一組成物である」と置換可能に用いられる。 Further, it has been clarified from the examples described later that the horse placenta hydrolyzate in the present invention is a hydrolyzate containing the largest amount of peptides as constituent components. Further, it has been clarified from the examples described later that the horse placenta hydrolyzate according to the present invention contains most of peptides having a molecular weight of 1,000 or more and less than 3,000 as a constituent. In the present invention, the phrase "contains the largest amount of peptides as constituent components" means that it contains the largest amount of peptides based on the total weight of constituent components (based on the weight% of constituent components). However, the phrase "contains the most peptide as a constituent" is used interchangeably with "(in the horse placenta hydrolyzate) the peptide as a constituent is the first composition having the maximum composition ratio".

Regarding the number of cells, as shown in Fig. 2, no difference was observed between each test substance and each concentration group. From this, it became clear that the cell growth promoting properties of each test substance were not observed. As for the amount of mitochondria, as shown in FIG. 3, a significant increase in the amount of mitochondria was observed in the horse-placenta hydrolyzate-added group after 3 days of culture. The effect of increasing the amount of mitochondria was not observed. On the other hand, no increase in mitochondrial amount was observed in porcine-derived low-molecular-weight high-grade gelatin and porcine-derived medium-molecular-weight high-grade gelatin. From these results, it was revealed that the addition of horse placenta hydrolyzate caused a short-term increase in the amount of mitochondria in fibroblasts.

続いて、ミトコンドリア活性評価について、図4に示すように、培養7日間以降の長期処理においてウマプラセンタ加水分解物処理によりミトコンドリア活性が顕著に増大したが、ブタ由来低分子量ハイグレードゼラチンおよびブタ由来中分子量ハイグレードゼラチンにおいては、ミトコンドリア活性増大作用は認められなかった。また、ミトコンドリア賦活作用の陽性対照として使用したレスベラトロールは培養21日間処理においてのみミトコンドリア活性増大作用が認められた。これらのことから、ウマプラセンタ加水分解物は、正常ヒト線維芽細胞のミトコンドリアの活性を増大させることが明らかとなった。また、I型コラーゲン産生評価について、図5に示すように、培養14日間、21日間においてウマプラセンタ加水分解物処理でI型コラーゲンの産生が増大したが、ブタ由来低分子量ハイグレードゼラチンおよびブタ由来中分子量ハイグレードゼラチンにおいてコラーゲンの増加は認められず、むしろ、一部減少が認められた。I型コラーゲン産生促進の陽性対照として使用したビタミンC(アスコルビン酸)ではいずれの培養区においても顕著なI型コラーゲン増加作用を示した。また、各被験物質中のコラーゲンがI型コラーゲンとして検出される可能性があることから、事前に被験物質を含む試験培地のコラーゲンを測定したが、いずれの培地においてI型コラーゲンは未検出レベルであった。これらのことから、ウマプラセンタ加水分解物は、正常ヒト線維芽細胞のI型コラーゲンの産生を促進させることが明らかとなった。 Subsequently, as to the evaluation of mitochondrial activity, as shown in FIG. 4, the mitochondrial activity was significantly increased by the treatment with horse placenta hydrolyzate in the long-term treatment after 7 days of culture. In high-molecular-weight gelatin, the effect of increasing mitochondrial activity was not observed. Further, resveratrol used as a positive control for mitochondrial activation was observed to increase mitochondrial activity only after treatment for 21 days in culture. From these results, it was revealed that the horse placenta hydrolyzate increases the activity of mitochondria of normal human fibroblasts. Regarding the evaluation of type I collagen production, as shown in FIG. 5, the production of type I collagen was increased by the treatment with horse placenta hydrolyzate during 14 days and 21 days of culture. In medium-molecular-weight high-grade gelatin, an increase in collagen was not observed, but rather a partial decrease was observed. Vitamin C (ascorbic acid), which was used as a positive control for promoting type I collagen production, showed a remarkable type I collagen-increasing action in all culture groups. In addition, since collagen in each test substance may be detected as type I collagen, collagen in the test medium containing the test substance was measured in advance. there were. From these, it was revealed that the horse placenta hydrolyzate promotes the production of type I collagen by normal human fibroblasts.

以上をまとめると、ウマプラセンタ加水分解物は、ヒト線維芽細胞のミトコンドリア量を増加させ、ミトコンドリアの活性を増大し、かつ、コラーゲン産生を促進する作用を有していることが明らかとなった。また、ウマプラセンタ加水分解物は、短期的な処理によってもミトコンドリア量を増加させ、さらに長期的な処理によりミトコンドリア活性を増大させることも明らかとなった。I型コラーゲンの産生が促進されたのは、 ヒト線維芽細胞中のミトコンドリアの活性に伴い、ヒト繊維芽細胞のI型コラーゲン産生能が高まったと考えられる。また、細胞数自体は各培養期間において変化がないことから、ウマプラセンタ加水分解物による、ヒト線維芽細胞のミトコンドリア量を増加させ、ミトコンドリアの活性を増大し、かつ、コラーゲン産生を促進する作用については、細胞増殖を伴う作用ではなく、細胞機能自体を促進したものと考えられる。 In summary, it was revealed that horse placenta hydrolyzate has the actions of increasing the amount of mitochondria in human fibroblasts, increasing the activity of mitochondria, and promoting collagen production. It was also clarified that the horse placenta hydrolyzate increased the amount of mitochondria by a short-term treatment and increased the mitochondrial activity by a long-term treatment. It is considered that the production of type I collagen was promoted because the ability of human fibroblasts to produce type I collagen increased due to the activity of mitochondria in human fibroblasts. In addition, since the cell number itself does not change during each culture period, there is an effect of increasing the mitochondrial amount of human fibroblasts, increasing the activity of mitochondria, and promoting collagen production by the horse placenta hydrolyzate. Is considered to have promoted the cell function itself, not the action involving cell proliferation.

6.スクラッチ法による細胞遊走試験
創傷治癒の過程では、傷に向かって線維芽細胞が増殖・遊走して創が収縮・閉鎖されることが知られており、これを利用してウマプラセンタの加水分解物による細胞遊走促進作用を検証することとした。具体的な試験方法は下記の通りである。
6. Cell migration test by scratch method In the process of wound healing, it is known that fibroblasts proliferate and migrate toward the wound, and the wound contracts and closes. It was decided to verify the cell migration-promoting effect of the. The specific test method is as follows.

[6−1]細胞遊走試験の試験方法
あらかじめ、60mmのDishの裏側に十字の線を描いておき、そこに、ヒト正常線維芽細胞を4000個/cmの割合で播種し、当該細胞がコンフルエントになるまで培養した後、コンフルエントな状態となった当該細胞を専用のスティックで剥がし、スクラッチした。続いて、本実施例に係るウマプラセンタ加水分解物試料を添加した培地または添加しない培地に交換し、0時間、24時間および48時間後に画像を撮影し、スクラッチによる十字の線を参考にして、空白部分への進む距離を測定した。なお、1ウェルにおいて2、3箇所測定して平均し、n数は4または5とした。その結果を図6に示す。
[6-1] Test method for cell migration test In advance, a cross line was drawn on the back side of the 60 mm dish, and human normal fibroblasts were seeded at a rate of 4000 cells/cm 2 , and the cells were After culturing until the cells became confluent, the cells in the confluent state were peeled off with a dedicated stick and scratched. Subsequently, the medium was added with or without the horse placenta hydrolyzate sample according to the present example, and images were taken after 0 hours, 24 hours, and 48 hours, with reference to the cross line due to scratch, The distance traveled to the blank part was measured. In addition, the number of n was set to 4 or 5 by averaging measured values at 2 and 3 points in one well. The result is shown in FIG.

[6−2]結果
図6に示すように、本実施例で用いるウマプラセンタの加水分解物を添加した場合(100μg/mL)は、当該添加しない場合と比較して、0時間、24時間、48時間と時間が経過するにつれ、ヒト正常線維芽細胞が増殖するとともに遊走活性が向上する。このことから、本実施例で用いるウマプラセンタの加水分解物は、創傷治癒能を有することが明らかとなった。また、上述の通り、従来、プラセンタエキス(プラセンタ抽出物)に含まれることが知られているEGF(上皮細胞増殖因子)、HGF(肝細胞増殖因子)、FGF(線維芽細胞増殖因子)などの成長因子は、タンパク質であるがゆえに、加水分解反応により分解・失活してしまうため、本発明に係る創傷治癒剤は、従来のプラセンタエキス(プラセンタ抽出物)の奏する創傷治癒効果とは異なるといえる。
[6-2] Results As shown in FIG. 6, when the hydrolyzate of horse placenta used in this Example (100 μg/mL) was added, 0 hours, 24 hours, As the time elapses for 48 hours, normal human fibroblasts proliferate and their migration activity improves. From this, it was revealed that the hydrolyzate of horse placenta used in this example has a wound healing ability. As described above, EGF (epithelial cell growth factor), HGF (hepatocyte growth factor), FGF (fibroblast growth factor), etc., which are conventionally known to be contained in placenta extract (placenta extract), Since the growth factor is a protein, it is decomposed and inactivated by a hydrolysis reaction. Therefore, the wound healing agent according to the present invention is different from the wound healing effect exhibited by the conventional placenta extract (placenta extract). I can say.
