Description
東京芝浦臓器から購入したウシ心膜の脂肪組織を除去した後、生理食塩水で洗浄した。洗浄後のウシ心膜組織(2 cm×2 cm)をプラスチックパックに入れ、5 mLの生理食塩水を加えてシーリングした後、冷間等方加圧装置で30℃、10000気圧の高静水圧処理(昇圧15分、圧力維持10分、減圧15分)を行った。
スパッタリング装置の基板ホルダーに上述した手順で得た脱細胞化組織をセットし、基板ホルダーの上にドット形状のパターンマスクを被せ、Ti(チタン)をターゲット材としてセットし、反応性スパッタリング(不活性ガス:Ar、反応性ガス:O2)を実施した。なお、本実験では、電力100 W、O2流量0.1 sccm、Ar圧力1 Pa、T-S距離50.0 mmという条件の下、ターゲット材を金属モードに維持した状態で、5つの脱細胞化組織をそれぞれ異なる成膜時間でスパッタリングすることにより、5つの試料(Ti薄膜のパターンが形成された脱細胞化組織)を得た。
冷間等方加圧装置を使用して、上述した試料(Ti薄膜をパターン成膜した脱細胞化組織)を生理食塩水で水戻しを行った。その後、ポリウレタンで作製した疑似生体(ファントム)の内部に、上述した試料を埋植し、当該試料の直下に金属クリップを埋植した。
