を有しうる。
光重合で2コンパートメントレンズを得るための操作(図3)
段階1.中央光学部の調製(溶液A)
光学および環状部の基本材料として、PBS中10%の重量/容量割合で平均分子量3400のポリ(エチレングリコール)ジアクリレート(PEGDA)を用いた。2‐ヒドロキシ‐1‐〔4‐(ヒドロキシエトキシ)フェニル〕‐2‐メチル‐1‐プロパノンをポリマー溶液の0.05%重量/容量の割合で開始剤として用いた。70%エタノール中開始剤溶液を使用直前に調製し、氷上で保ち、光入射を避けた。
ポリマー溶液を得る
環状部の基本ポリマー溶液を得るための操作は、1期で記載されたものと同様であった。しかしながら、この場合にポリマー溶液が細胞を受容して可能な細胞毒性作用を制限するものであるとすれば、後でUV光への暴露のために型へ混合液の投入の瞬間に開始剤を加えた。
活性物質で負荷された生分解性小球を制御放出治療システムとして用いた。この場合には、デキサメタゾン(眼科で広く用いられているステロイド抗炎症剤)で負荷されたポリ(乳酸‐コ‐グリコール酸)(PLGA)ミクロおよび/またはナノ小球を用いることになり、連続水相中にポリマーおよび薬剤の有機溶液を分散させた油相/水相(O/W)エマルジョンから溶媒の蒸発に基づくミクロ/ナノ封入技術を用いた。
800mg PLGA50:50(インヘレント粘度0.17〜0.24dL/g)、2mLジクロロメタンおよび80〜160mgデキサメタゾンを含んでなる有機相を1分間攪拌し、氷上で更に1分間超音波に曝した。1%(Pm72000)で5mLポリビニルアルコール(PVA)を含んでなる水相にこの溶液を滴下し、5000rpmで2分間均質化させた。容量を0.1%のポリビニルアルコールで15mLに調整し、更に1分間均質化させた。このエマルジョンを0.1%の容量20mL PVAへ加え、磁気で3〜4時間攪拌した。成熟ミクロ小球を蒸留水で3回洗浄し、それらを篩にかけ、20〜50μmサイズのものを濾取した。最後に、貯蔵のために真空下2〜4℃で凍結乾燥させた。
15mLジクロロメタン中800mg PLGA50:50(インヘレント粘度0.17〜0.24dL/g)と15mLアセトンに溶解された200mgデキサメタゾンからなる有機相を5分間攪拌した。、次いで5%ポリビニルアルコール(Pm72000)を含んでなる200mLの水相へこの有機相を滴下した。エマルジョンを60Wで10分間の超音波への暴露により形成させ、それを氷上で保った。環境温度で12時間磁気攪拌することにより溶媒の蒸発を行った。成熟ナノ小球を蒸留水で3回洗浄し、4℃にて35,000rpmで1時間の遠心により回収した。最後に、貯蔵のために真空下2〜4℃で凍結乾燥させた。
目の摘出前に、その領域を塩水溶液中ヨウ素溶液で洗浄した。外科用メス(No.12)を用いて角膜を摘出し、氷上に保たれた1%ペニシリンおよびストレプトマイシン含有の抗生物質溶液入りDMEM‐F12培地に集めた。角膜を四分割し、142rpmおよび37℃で30〜45分間にわたりコラゲナーゼの酵素培地(1mL DMEM‐F12中3.3mgコラゲナーゼ〔SIGMA.Ref.C8176〕)へ入れた。この1回目消化の内容物を濾過し、前記と同条件下で更に1時間の消化(2回目消化)を行うために、得られた組織を新鮮コラゲナーゼ培地へ再び再懸濁した。2回目濾過後(上澄は保存する)、操作を繰返し、フィルターに留まる内容物を再び142rpmおよび37℃で2時間半にわたり新鮮酵素培地に再懸濁した。この3回目消化後、上澄を集めた。間質角膜実質細胞を含む2回目および3回目消化からの培地を集め、遠心し、細胞生存性を調べるために既知量のDMEM‐F12へ再懸濁した。この時点で、2つのオプションがある。1)(次のセクションで記載されているように)一次角膜実質細胞を封入すること、またはそれらをインキュベートして封入しうる線維芽細胞を得ること
光開始剤を含有するポリマーPEGDA溶液とデキサメタゾンで負荷されたPLGA小球を含んでなる混合液を調製した。攪拌機でこの組成物を1分間維持した後、4℃で10分間にわたる角膜実質細胞の細胞懸濁液の遠心後に既に得られた細胞タブレットにそれをチップした。
溶液AおよびBを型の対応キャビティへ入れた(4.1)。型を閉じた後(4.2)、それらをサンプルの均質化のための運動に付し、光重合を開始させるためにそれらをUV光に曝した(4.3)。このように、この第一段階では、光学部および環状部に相当する2つの個別疑似ゲルを強度4mW/cm2およびλ=365nmのUV光下において1〜2分間で得た。
