Abstract
Description
本発明は、TRPチャネルのアゴニストおよび/またはTRPCのアンタゴニストを含む、細胞、組織または器官用保存液に関する。 The present invention relates to cell, tissue or organ preservatives containing agonists of TRP channels and / or antagonists of TRPC.
細胞、組織、または器官を用いた実験や臓器移植等を実施する場合、実施に供する前に細胞、組織、または器官の適切な保存が必要とされる。例えば、臓器移植において、摘出された臓器がレシピエントに移植されるまで品質の低下を抑えるために適切に保存しておく必要がある。 When conducting experiments using cells, tissues, or organs, organ transplantation, etc., proper preservation of cells, tissues, or organs is required before the performance. For example, in organ transplantation, it is necessary to properly store the excised organ until it is transplanted to a recipient in order to prevent deterioration of quality.
これまでに、冷蔵保存液であり、フリーラジカルを捕捉する物質を含み、低温での細胞状態のバランス最適化(pH緩衝、膠質浸透圧、エネルギー基質、イオン濃度)が図られたHypothermosol(商標)が知られている。また、冷蔵で短期間保存するための保護液であり、生体由来物質および保存補助剤を含まず、無機塩類とグルコースのみで構成された液であるCPS(商標)−1が知られている。さらに、肺組織/細胞の冷蔵保存液であり、細胞外液に近いイオン組成で、DMSOや血清タンパク質が含まれない保存液であるStemSurvive−lungが知られている。また、特許文献1には、細胞傷害に対して細胞を保護するために使用できるクロマン誘導体が開示されている。 Hyposthermosol ™, which is a refrigerated storage solution, contains a substance that traps free radicals, and has been optimized for the balance of cell state at low temperature (pH buffer, oncotic pressure, energy substrate, ion concentration). It has been known. Further, CPS ™ -1, which is a protective liquid for short-term storage in a refrigerator, does not contain a biological substance and a storage aid, and is composed only of inorganic salts and glucose, is known. Further, StemSurvive-rung, which is a refrigerated storage solution for lung tissue / cells and has an ionic composition close to that of extracellular fluid and does not contain DMSO or serum protein, is known. In addition, Patent Document 1 discloses a chroman derivative that can be used to protect cells against cytotoxicity.
臓器移植に際し、ドナーから提供された臓器は代謝低下を目的に低温保存された状態で輸送されている。摘出臓器は血流が遮断され阻血状態となるが低温での代謝抑制により阻血の影響を軽減させている。それでも、臓器移植時の阻血許容時間は心臓で4時間、肺で8時間と臓器に依っては短く、低温保存時間の延長が強く求められている。 At the time of organ transplantation, the organs donated by the donor are transported in a cryopreserved state for the purpose of lowering metabolism. Blood flow is blocked in the excised organ and it becomes ischemic, but the effect of ischemia is reduced by suppressing metabolism at low temperature. Nevertheless, the permissible time for ischemia at the time of organ transplantation is as short as 4 hours for the heart and 8 hours for the lungs, depending on the organ, and there is a strong demand for extension of the cryopreservation time.
また、再生医療に関する研究開発が進み、細胞が原料となる再生医療等製品も開発される状況で、製品の凍結保存はもちろん、冷蔵保存や輸送時の保存の必要性が顕在化してきている。臓器に限らず細胞等の保存性能が高い保存液は未だ希求されているといえる。 In addition, research and development related to regenerative medicine is progressing, and products such as regenerative medicine using cells as raw materials are being developed, and the necessity of refrigerating storage and storage during transportation as well as cryopreservation of products has become apparent. It can be said that there is still a need for a preservation solution having high preservation performance not only for organs but also for cells and the like.
本発明者らは、驚くべきことに、特定のTRPチャネル作用物質を含む保存液を用いることにより、細胞、組織、または器官を良好な状態に保ったまま保存できることを見出した。本発明は、これらの知見に基づくものである。 The inventors have surprisingly found that cells, tissues, or organs can be preserved in good condition by using a preservation solution containing a specific TRP channel agonist.

(9)PBS(リン酸緩衝生理食塩水、Phosphate buffered salts)100μlで2回洗浄して、細胞培養培地(15%牛胎児血清、1%ペニシリン/ストレプトマイシン、2mMグルタミン、およびMEM用非必須アミノ酸を含むEMEM培地(DSファーマバイオメディカル株式会社製)/F−12 Ham培地(Sigma社製)の50/50の混合培地)を100μl加え、37℃炭酸ガスインキュベーターで回復培養前サンプルとして60分間培養をし、24時間回復培養後サンプルとして24時間回復培養を行った。
(10)生細胞数測定試薬SF(ナカライテスク株式会社製)溶液を回復培養前サンプルと、24時間回復培養後サンプルとのそれぞれの各ウェルに10μlずつ添加した。
(11)炭酸ガスインキュベーター内で4時間呈色反応を行った。
(12)マイクロプレートリーダーを用い、回復培養前サンプル(回復培養前)と、24時間回復培養後サンプル(24時間の回復培養後)の細胞について、450nm(参照波長:650nm)の吸光度を測定した。マイクロプレートリーダーはSpectraMax Plus 384 Microplate Reader(Molecular Devices社製)を用いた。
上記の結果を図5に示す(グラフの縦軸は、各サンプルにおける回復培養前のサンプル(48h保存時)の吸光度を100としたときの24時間回復培養後のサンプルの相対値である)。
After storage for 48 hours (8), the cells were cultured in a carbon dioxide incubator at 37 ° C. for 60 minutes.
(9) Wash twice with 100 μl of PBS (Phospate buffered salts) to add cell culture medium (15% bovine fetal serum, 1% penicillin / streptomycin, 2 mM glutamine, and non-essential amino acids for MEM). Add 100 μl of EMEM medium (50/50 mixed medium of DS Pharma Biomedical Co., Ltd.) / F-12 Ham medium (manufactured by Sigma), and incubate for 60 minutes as a sample before recovery culture in a 37 ° C. carbon dioxide gas incubator. Then, after the recovery culture for 24 hours, the recovery culture was performed for 24 hours as a sample.
(10) 10 μl of a solution of a reagent for measuring the number of living cells SF (manufactured by Nacalai Tesque, Inc.) was added to each well of the sample before recovery culture and the sample after recovery culture for 24 hours.
(11) A color reaction was carried out in a carbon dioxide incubator for 4 hours.
(12) Using a microplate reader, the absorbance of 450 nm (reference wavelength: 650 nm) was measured for the cells of the pre-recovery culture sample (before recovery culture) and the 24-hour recovery culture sample (after 24-hour recovery culture). .. As the microplate reader, a SpectraMax Plus 384 Microplate Reader (manufactured by Molecular Devices) was used.
The above results are shown in FIG. 5 (the vertical axis of the graph is the relative value of the sample after 24-hour recovery culture when the absorbance of the sample before recovery culture (when stored for 48 hours) in each sample is 100).
図5の結果によれば、本発明のTRPチャネル作用物質を用いた場合、24時間の回復培養後で、イシリンを添加した場合の方が、本発明のTRPチャネル作用物質を添加しないものに比べて、吸光度(相対値)が高くなり、細胞の増殖能がより保存されていることが分かる。 According to the results of FIG. 5, when the TRP channel agonist of the present invention was used, the case where icylin was added after the recovery culture for 24 hours was better than the case where the TRP channel agonist of the present invention was not added. Therefore, it can be seen that the absorbance (relative value) is increased and the proliferative ability of the cells is more conserved.
一方、図5には示していないが、市販品であるROKEPIE(商標)(Sulfateq B.V.社製)、Hypothermosol(商標)(BioLife Solutions社製)、またはCPS(商標)−1(株式会社細胞科学研究所製)を、本発明のTRPチャネル作用物質(イシリン)の代わりに添加して上記の回復能の評価を行った。これらの市販品では、24時間の回復培養後で、回復培養前と比べて吸光度はほとんど上昇せずに、コントロールと同様に細胞の増殖が止まってしまうことが分かり、本発明のTRPチャネル作用物質(イシリン)の方が細胞の増殖能の保存の点で優れた効果を示すことが分かった。 On the other hand, although not shown in FIG. 5, commercially available products such as ROKEPIE (trademark) (manufactured by Sulfateq VV), Hyperthermosol (trademark) (manufactured by BioLife Solutions), or CPS (trademark) -1 (manufactured by BioLife Solutions Co., Ltd.) (Manufactured by Cell Science Laboratory) was added in place of the TRP channel agonist (icirin) of the present invention, and the above-mentioned recovery ability was evaluated. It was found that in these commercially available products, after 24 hours of recovery culture, the absorbance was hardly increased as compared with that before recovery culture, and cell proliferation stopped as in the control, and the TRP channel agonist of the present invention was found. It was found that (icillin) was more effective in preserving the proliferative capacity of cells.
