- a cryopreservative such as 5 to 20% dimethyl sulfoxide, glycerin, ethylene glycol, propylene glycol
- dimethyl sulfoxide is the most effective and frequently used.
- dimethyl sulfoxide is physiologically toxic, especially at high concentrations, and is known to cause hypertension, nausea and vomiting in patients injected with cryopreserved cells. Due to the toxicity of dimethyl sulfoxide, there is also a problem that the survival rate and function of the thawed cells are lowered during culture or after being injected into a living body.
- cryopreservatives such as glycerin are less effective, it is necessary to suspend the cells and leave them at room temperature or refrigerated for a while before freezing them, or strictly control the temperature with a program freezer or the like. In addition, there are problems such as low freezing protection effect and reduced function after thawing.

- Patent Documents 3 to 4 when manufacturing ice for medicines, foods, and displays, salts such as sodium chloride and saccharides such as glucose and trehalose are also added. Furthermore, the addition of antifreeze proteins and antifreeze glycoproteins produced by plants, fish and insects is known (Patent Documents 3 to 4).
- water is generated at one electrode with an electrochemical reaction.
- water is generated at the cathode electrode.
- a part of the generated water moves to the anode side through the electrolyte membrane.
- the gas flow in the fuel cell may be hindered.
- battery performance may fall by supply of the gas to an electrode being hindered.
- water retention is achieved by providing a hydrophilic coating film such as protein on the inside of the fuel cell, for example, the surface of the gas separator.
- Patent Document 5 a method of adding an antifreeze protein that suppresses the growth of ice crystals from liquid water together with the polymer electrolyte to the curable resin that forms the surface layer of the solid polymer electrolyte membrane (Patent Document 5), but this also has problems such as high cost.
- cryopreservation method including the quick freezing method
- Dimethyl sulfoxide is known to induce differentiation such as HL-60 cells, and some cells are not suitable for preservation.
- antifreeze protein and antifreeze glycoprotein are excellent in the effect of preventing freeze concentration, they are too expensive (1.3 million yen / g) and have limited application to foods.
- an object of the present invention is to provide a cryopreservation agent that is low in toxicity and excellent in the effect of protecting cell tissues, in place of dimethyl sulfoxide.
- the present invention provides an inexpensive and safe product that has the effect of preventing freeze-concentration equivalent to that of antifreeze protein and antifreeze glycoprotein when performing frozen storage and freeze-dry storage of foods and medicines. It is something to try.
- the cryopreservation solution of the present invention contains substantially 1-50% of a polyamine having an amino group in the side chain, and the other composition is a physiological solution such as physiological saline or a culture solution component.
- cryopreservation agents such as dimethyl sulfoxide, which are highly toxic by immersing animal cells and plant cells including various humans in the preservation solution and cryopreserving them in liquid nitrogen or liquid nitrogen vapor. Can be preserved while maintaining the survival rate and physiological activity. Since existing cryopreservatives such as dimethyl sulfoxide, glycerin, and ethylene glycol are not used, toxicity to frozen cells is kept low, and cryopreservation can be performed for a long time while maintaining the function. In addition, since protein components such as fetal bovine serum and albumin are not used, there is no concern about infectious diseases and the difference between lots due to biologics is not affected.
- Polyamines having an amino group in the side chain are considered to have a cell-protecting effect because of their affinity for cell membranes.
- polymer compounds with many carboxyl groups in the molecule have a high affinity with water, and help to expel the intracellular fluid quickly during freezing, thus providing a protective effect during cryopreservation of cells.
- a further excellent cytoprotective effect upon freezing can be expected.
- a polyamino acid having a cationic substituent such as an amino group in the side chain or a polymer compound having an anionic substituent such as a carboxyl group and a high molecular weight having both a cationic substituent and an anionic substituent.
- cryopreservation agent of the present invention is less toxic than DMSO, it does not require washing after thawing, and can be cultured immediately by adding it to the medium as it is.
- the present invention it is possible not only to stably carry out cryopreservation of experimental cultured cells, but also functional cells such as islets and stem cells, and stem cells such as ES cells, mesenchymal stem cells, and iPS cells. Since it can be stored without losing its function, it is expected that the efficiency of cell transplantation will be improved.
- non-freezing polyamino acid of the present invention it is possible to suppress the deactivation of the physiologically active substance when the hydrate containing the physiologically active substance is frozen. Furthermore, by using the non-freezing polyamino acid of the present invention, it is possible to homogenize the diffusion of the components in a frozen product or a freeze-dried product obtained by freezing or freeze-drying a hydrate containing components other than water molecules. it can. Examples of frozen products include ice cream, sherbet, ice confectionery, display ice, and frozen soup.

Abstract
Description
ε-ポリ-L-リジン(チッソ社製、分子量4000)は25%水溶液のものを、ポリアリルアミン(日東紡、分子量5000(PAA-05L)、15000(PAA-L)、60000(PAA-H))は20%水溶液のものを用い、分子中のアミノ基に対し、モル%で0-100%の無水コハク酸(和光純薬工業製)を添加することでアミノ基のブロック率の異なるポリアミンを作成した。それぞれのポリアミン溶液をダルベッコ改変培地(DMEM、シグマアルドリッチ製)に0-10w/w%となるように添加した。この際、pHが7.0-8.0の範囲内になるように1Nの塩酸もしくは水酸化ナトリウム水溶液で中和した。また、溶液の浸透圧はWescor社製5520型蒸気圧法オズモメーターにて測定し、浸透圧の調整には10%塩化ナトリウム水溶液を用いた。
1×106個のL929, MG63, Caco-2細胞(大日本住友製薬), colon26, HT1080, B16F1, KB細胞(ATCC)をクライオバイアル(Simport Plastics)中で各凍結保存液1mLに懸濁し、-80℃のフリーザー中で凍結保存を行った。1週間後、37℃の温浴中で速やかに融解し、DMEMで洗浄したのち、トリパンブルー染色により生死判定を行った。また、解凍した細胞は6wellカルチャーディッシュに1×105個ずつ播種し、6時間後、24時間後のそれぞれの生存率をトリパンブルー染色により評価した。比較例としては一般的によく用いられている保存液である10%DMSO/ウシ胎児血清(FBS)を用いた。
L929細胞を用いた毒性試験を行った。10%ウシ胎児血清を含有したダルベッコ改変イーグルMEM培地(DMEM)に懸濁させたL929細胞を、96wellマイクロプレートに1.0×103cell/well播種し、37℃で72時間培養後、ε-ポリ-L-リジン、及び、種々の濃度の無水コハク酸を添加したポリリジンを、最終濃度0-10%となるように添加し、48時間後、未添加系をコントロールとして細胞の増殖が50%阻害される濃度をIC50とし、MTT法で求めた。その結果を表2に示す。比較例はDMSO系(10%DMSO/ウシ胎児血清)とした。表2の結果から知られるように、PLL無水コハク酸58%、63%、79%のIC50は、DMSO系の場合の2~3倍であった。すなわち、上記実施例で用いた部分ブロック化ポリリジンの毒性は、従来一般的な凍結保存液の1/2~1/3と判断された。特には、図1のデータにて細胞生存率が高かったPLL無水コハク酸63%と、PLL無水コハク酸58%とにおいて、IC50の値が特に大きかった。
ラット間葉系幹細胞(RMSC)の凍結保存を行った。比較例の保存液は10%DMSO/ウシ胎児血清であり、実施例の保存液はPLL無水コハク酸63%の7.5%溶液(図4中に7.5%PLL(0.63)と表示)である。
臍帯血は、血液抗凝固剤(EDTA2Na)を10.5mg充填された7mLプラスチック製真空採血管(テルモ株式会社製、ベノジェクト2真空採血管)を使用してヒト臍帯より採取した。次いで、このように抗凝固剤を添加したヒト臍帯血中に、7.5%となるようにPLL無水コハク酸63%(7.5%PLL(0.63))を添加し、-80℃のフリーザー中で3ヶ月間凍結保存した。37℃の温浴中で速やかに融解し、希釈等を行わないままのヒト臍帯血を一部採取して、造血幹細胞の表面マーカーであるCD34の発現率をフローサイトメトリー法を用いて測定した。CD34造血幹細胞数をフローサイトメトリーを用いて、文献(A. Higuchi et al., J. Biomed. Mater. Res., 68A, 34-42 (2004))記載の常法により測定した。すなわち、CD34造血幹細胞数は、Stem-Kit(ベックマン・コールター社製)を用いて、そのマニュアル(国際血液療法・移植学会 ISHAGEガイドライン)に従って行った。3ヶ月後においても、CD34造血幹細胞数は、初日に計測された70%前後の細胞数が観察された。一方、10%DMSO溶液で凍結保存したヒト臍帯血中のCD34造血幹細胞数は、初日に計測された20%前後の細胞数であった。このように、ε-ポリ-L-リジンを添加した保存液でヒト臍帯血を保存すると、CD34造血幹細胞を未分化の状態で長期間保存できることが明らかとなった。
PLL(ε-ポリ-L-リジン)および無水コハク酸処理PLLの不凍タンパク質活性を調べた。すなわち、氷の再結晶を阻害する効果について調べた。不凍タンパクには種々の特殊な活性が知られており、氷の表面に吸着することなどにより、熱ヒステリシス、氷の再結晶成長抑制、氷晶の六方晶もしくはバイピラミッド状への形態変化を引き起こすことが知られている(特許文献3~4)。
凍結濃縮防止(凍結融解寒天ゲル);寒天末(1級試薬 ナカライテスク(株)社製)にPLL無水コハク酸63%を添加して5%溶液を調整し、この溶液に赤色インクを添加しプラスチック容器に入れ-20℃にて凍結した後、常温で解凍した。結果を図7の写真に示す。左が無添加のもの、右がPLL琥珀酸誘導体5%添加のものである。無添加のものは赤色の部分(不透明な上半部)と、透明な部分(ゲルを載せた箇所の右上に影を生じさせているが、ゲルの下方のペーパータオルのメッシュ模様が透けて見えている部分)とに、明らかに分離しているのが解かる。一方、PLL琥珀酸誘導体5%添加物は解凍ゲル全体が均一に赤色を呈し、凍結濃縮が防止できているのが知られた。
