図1は細胞培養部材1の断面説明図であり、図2は培養部位13を取り除いた細胞培養部材1の説明図であり、図2(a)は断面説明図、図2(b)は平面説明図である。
続いて第一の細胞種にかかる細胞培養方法を説明する。細胞の培養に先立ち、細胞培養部材を準備する。
ホットプレート(50℃)上で易接着処理のしてあるPETフィルム(テイジンテトロンフィルムG274)上にアガロース水溶液(80℃、5%)をバーコーティングした。オーブン中で40℃、30分間加熱乾燥した。
播種(培養)細胞はHUVECを使用した。HUVECを所定の培養液で培養後、1日前にmediumをmedium199+0.5%FCS(仔牛血清)+1%P/S (ペニシリンストレプトマイシン)に交換して培養した。当該培養は飢餓処理(starvation処理)である。細胞培養実験直前に、コラゲナーゼ処理によりHUVECをはがした。得られたHUVECをPKH26により蛍光標識した。
24well plate下部にVEGF含浸ゼラチンパターニング基材を静置し、24well cell culture insert上部に培養部位であるマトリゲル(matrigel)層を作製した。マトリゲルの濃度は10mg/mlであった。当該マトリゲル溶液を20μl用いたものと、50μl用いたものの2種類の細胞培養部材を使用した。マトリゲル溶液20μlの場合にマトリゲル層の厚さは約0.7mmであり、マトリゲル溶液50μlの場合にマトリゲル層の厚さは約1.7mmであった。コントロールは、24well plate下部に純水含浸ゼラチンパターニング基材を静置し、24well cell culture insert上部に培養部位であるマトリゲル(matrigel)層を同様に作製した。
培養終了後、プレートリーダーでcell culture insert下部の蛍光強度を測定することで、培養部位(マトリゲル層)下部へ移動したHUVEC細胞数を評価した。
