Description
多孔性
層の多孔性は、本明細書中では、細孔空間からなる層体積の層の総体積と比べた割合として定義される。多孔性は、以下の等式を用いて中実分率および空隙分率で構成される多孔性構成体の嵩密度を中実分率の密度と比較することによって計算される:
生体適合膜複合材料中の層の厚みを、横断面SEM画像の定量的画像解析(QIA)によって測定した。接着剤に膜を固定し、液体窒素で冷却したかみそりの刃を用いて手でフィルムを切断し、その後、横断面が垂直になるように裏面接着剤付きフィルムを立てることにより、横断面SEM画像を生成した。その後、Emitech K550X スパッタコータ(Quorum Technologies Ltd.UKより市販)および白金標的を用いて、試料をスパッタコーティングした。その後、Thermo Scientific社のFEI Quanta 400走査型電子顕微鏡を用いて、試料を画像化した。
非強化および強化プラスチックおよび電気絶縁材料の曲げ特性についてのASTM D790-17規格の試験方法に基づいて、剛性試験を行なった。この方法は、生体適合膜複合材料層および/または最終的デバイスの剛性を決定するために使用した。
5500 Series Instron(登録商標)Electromechanical Testing Systemを用いて、材料の引張り強度を試験した。別段の指摘の無いかぎり、何らかのコーティングを適用する前に材料を試験した。D412FまたはD638-V型ドッグボーンダイを用いて、試料を切断した。その後、試料をInstron(登録商標)テスターグリップ内に装填し、破損に至るまで20in/min(D412F試料について)または3in/min(D683-V試料について)の恒常な速度で試験した。試験面積(ゲージ幅×材料厚みとして定義される)により、最大荷重を正規化して、引張り強度を定義した。材料を、直交する方向(D1およびD2)で試験し、各方向における最大応力を用いて、以下の等式により材料の幾何平均引張り強度を計算した:
5500 Series Instron(登録商標) Electromechanical Testing Systemを用いて、最大引張荷重について材料を試験した。D412FまたはD638-V型ドッグボーンダイを用いて、対象の軸に配向した状態で試料を切断した。その後、試料をInstron(登録商標)テスターグリップ内に装填し、破損に至るまで20in/min(D412F試料について)または3in/min(D683-V試料について)の恒常な速度で試験した。試料中持続した最大荷重を、供試体ゲージ幅(D412F試料については6.35mm、D638-V試料については3.175mm)により正規化して、最大引張荷重を定義した。
5500 Series Instron(登録商標)Electromechanical Testing Systemを用いて、複合材料結合強度について材料を試験した。別段の指摘の無いかぎり、何らかのコーティングを適用する前に材料を試験した。3M9500PC両面テープを用いて、1’’×1’’(2.54cm×2.54cm)の鋼製プラテンに試料を固定し、表面上に3M9500PC両面テープを伴う相対する1’’×1’’の鋼製プラテンを有するInstron(登録商標)内に装填した。接着剤が部分的に構造に貫入できるように60秒間、1001Nの特徴的圧縮荷重を適用した。この結合の後、プラテンを、破損するまで20in/sの恒常な速度で分離した。最大荷重を、試験面積(1’’×1’’の試験面積として定義される)によって正規化して、複合材料の結合を定義した。
試料を公知の幾何形状に(手作業、レーザーまたはダイのいずれかによって)切断した。別段の指摘の無いかぎり、何らかのコーティングを適用する前に材料を試験した。試料の寸法を測定または確認し、面積をm2単位で計算した。その後、試料の重量を較正済みスケール上でグラム単位により測定した。グラム単位の質量をm2単位の面積で除して、g/m2の面積あたり質量を計算した。
画像化用に意図された側とは反対の側が接着剤に面している状態で、取扱いのために接着剤上に膜複合材料または膜複合材料層をまず固定することによって、SEM試料を調製した。その後、フィルムを切断して、画像化のためにおおよそ3mm×3mmの面積を提供する。その後Emitech K550Xスパッタコータおよび白金標的を用いて、試料をスパッタコーティングした。次に、各々の特徴部の最小寸法が少なくとも長さ5画素となるように保証しながら、ロバストな解析のために充分な数の特徴部の視覚化を可能にする倍率および解像度でThermo Scientific社のFEI Quanta400走査型電子顕微鏡を用いて、画像を撮った。
National Institute of Health(NIH)製のImage J1.51h内でSEM画像を解析することによって、中実特徴部を決定した。SEM画像が提供するスケールに基づいて、画像スケールを設定した。サイズに基づく閾値化/シェーディングおよび/または手作業での識別の組合せを通して、特徴部を識別し、単離した。離散的な中実特徴部を伴う構造とは対照的に、構造が不織またはエッチングされた表面などの連続的構造で構成される事例では、中実特徴部は、空隙を取り囲む構造の部分として定義され、それらの対応する離隔距離は空隙の一方の側から反対の側まで延在する。特徴部を単離した後、隣接する特徴部を識別するために、ドロネー三角形分割を行なった。画像の縁部を超えて外接円が延在する三角形分割は、解析では無視した。隣接する特徴部の最も近い縁部の間に線を引き、長さを測定して、隣接する特徴部間の離隔距離を定義した(例えば図1Aを参照)。
NIH製のImage J1.51h内で膜表面のSEM画像を解析することによって、代表的短軸を測定した。SEM画像が提供するスケールに基づいて、画像スケールを設定した。サイズに基づく閾値化/シェーディングおよび/または手作業での識別の組合せを介して、特徴部を識別し単離した。特徴部を単離した後、内蔵された粒子解析能力を活用して、代表的な楕円の長軸および短軸を決定した。この楕円の短軸は、測定された特徴部の代表的短軸である。この楕円の長軸は、測定された特徴部の代表的長軸である。全ての測定された短軸の中央値は、測定された短軸の半分以下でかつ測定された短軸の半分以上である値を示す。同様にして、全ての測定された長軸の中央値は、測定された長軸の半分以下でかつ測定された長軸の半分以上である値を示す。両方の場合において、測定された中央値が、或る値より上または下である場合、測定値の大部分は同様にこの値より上または下である。したがって、中央値は、中実特徴部の代表的短軸および代表的長軸の大部分を代表するための要約統計量として使用される。
膜横断面のSEM画像の定量的画像解析(QIA)を使用することによって、中実特徴部深さを決定した。接着剤にフィルムを固定し、液体窒素で冷却したかみそりの刃を用いて手でフィルムを切断し、その後、横断面が垂直になるように裏面接着剤付きフィルムを立てることにより、横断面SEM画像を生成した。その後、Emitech K550X スパッタコーター(Quorum Technologies Ltd. UKより市販)および白金標的を用いて、試料をスパッタコーティングした。その後、Thermo Scientific社のFEI Quanta 400走査型電子顕微鏡を用いて、試料を画像化した。
NIH製のImage J1.51h内で膜表面のSEM画像を解析することによって、細孔サイズを測定した。SEM画像が提供するスケールに基づいて、画像スケールを設定した。サイズに基づく閾値化/シェーディングおよび/または手作業での識別の組合せを介して、細孔を識別し単離した。細孔を単離した後、内蔵された粒子解析能力を活用して各細孔の面積を決定した。測定された細孔面積を、以下の等式によって、「有効直径」へと転換した:
Anton Paar社製のQuantachrome 3Gzhポロメータおよび湿潤溶液としてのシリコーン油(20.1dyne/cm)を用いて、ASTM F316により、MPS(最大細孔サイズ)を測定した。
インビトロで酸素拡散距離(ODD)を査定するために、内部に細胞が無い細胞カプセル化デバイスを1.0PSIまで加圧して、カプセル化細胞のインビボ効果をシミュレートする。カプセル化細胞は、周囲の組織よりおよそ1.0PSI高い圧力を及ぼすものと仮定されるという点に留意すべきである。
例えばhESおよびiPS細胞などの万能性幹細胞のための本明細書中の指向性分化方法は、所望される最終段階の細胞培養または細胞集団(例えば、PDX陽性膵臓内胚葉細胞集団(またはPEC)、または内分泌前駆体細胞集団、または内分泌細胞集団、または未成熟ベータ細胞集団、または成熟内分泌細胞集団)に応じて、少なくとも4つまたは5つまたは6つまたは7つの段階で説明することができる。

少なくともMartinsonら、に対する米国特許第8,278,106号の教示中に記載されている通り、膵臓始原体細胞約6~7×106個(または約20μL)をエクスビボでカプセル化デバイスに装填した。24~96時間未満の間培地中に保持した後、2つのデバイスを、各々の雄の免疫不全無胸腺ヌードラットの体内で皮下に移植した。膵臓始原体細胞をインビボで発達させ成熟させ、移植後は、12、16、20および23~24週目にグルコース刺激性インシュリン分泌(GSIS)アッセイを行なうことによって、移植片の機能的性能を測定した。
カプセル化された膵臓始原体細胞の移植を受けた動物は、移植片の機能を監視するため、デバイス移植後12、16、20および23~24週間後に、グルコース刺激性インシュリン分泌アッセイを受けた。動物を4~16時間絶食させ、頸静脈穿刺により血液試料を採取し、その後、無菌の30%のグルコース溶液の腹腔内注射を介して体重1kgあたり3gの用量でグルコースを投与した。グルコース投与の90分後、または60分および90分後、または30分および60分後に、再度血液試料を抜き取った。全血から血清を分離し、その後、市販のELISAキット(Mercodia、カタログ#10-1141-01、Uppsala Sweden)を用いて、ヒトCペプチドについてアッセイを行なった。ベータ細胞は、等モル比でプロインシュリンからのインシュリンと共にCペプチドを同時放出し、Cペプチドは、血中の半減期が比較的長いことから、インシュリン分泌についてのサロゲートとして測定される。
移植後の標示された時点において、ヌードラットを安楽死させ、デバイスを外植した。余剰の組織をトリミングし、デバイスを少なくとも約6~30時間、中性緩衝10%ホルマリン中に置いた。固定したデバイスを、Leica Biosystems ASP300S 組織処理装置内でパラフィン包埋用に処理した。処理したデバイスを、各々およそ5mmの4~6個の部片に切断し、パラフィンブロック内に共に包埋した。各ブロックから、3~10ミクロンの多数の横断面を切断し、スライド上に置き、ヘマトキシリンとエオジン(H&E)で染色した。Hamamatsu Nanozoomer 2.0-HT Digital Slide Scannerを用いて、スライドの画像を捕捉した。
各デバイス内で使用された生体適合膜複合材料を除いて、同一の細胞カプセル化デバイスを作成した。1つのデバイス(デバイスA)は、細胞不浸透性層としてePTFE膜そして血管新生層として不織ポリエステルを伴う2層生体適合膜複合材料からなり、一方、第2のデバイス(デバイスB)は、細胞不浸透性層としてePTFE膜をそして血管新生層として不織ポリエステルを伴うものの、細胞不浸透性層と血管新生層の間に位置付けされた緩和層として別のePTFE膜が付加された3層生体適合膜複合材料からなっていた。
実施例1で説明した細胞カプセル化デバイスの形態を構築するために、三(3)つの層を含む代替的膜複合材料を使用した。唯一の差異は、デバイス管腔の外周シール間の溶接離隔距離を意図的に変動させるためにデバイスの幾何形状が修正されたという点にあった。
3つの明確に異なる層を有する生体適合膜複合材料を構築した。Goreに対する米国特許第3,953,566号の教示にしたがって、ePTFE膜(細胞不浸透性層)で形成された第1の層を形成した。
補強用構成要素を生体適合膜複合材料の表面に結合する内部点が全く存在しないという点を除いて、実施例3において説明された生体適合膜複合材料およびデバイスを使用した。このデバイス実施形態の目的は、適切な酸素拡散距離を維持する上での内部ボンド点の影響を実証するための比較例を提供することにある。
使用される膜複合材料および使用される内部補強用構成要素の幾何形状を除いて、実施例3で説明されている通りにデバイスを構築した。
異なる膜複合材料が使用されているという点を除いて、実施例4のデバイスCにおいて説明された通りに、3つの異なるデバイスを構築した。この実施例のために構築されたこれらのデバイスは、内部補強用構成要素を伴うデバイス内で使用されたさまざまな血管新生層を実証するように意図されている。
実施例3で説明されている通りの生体適合膜複合材料を作製し、図40Aで示されている細胞カプセル化デバイス4000へと形成した。この実施例中に記載の細胞カプセル化デバイスは、細胞カプセル化デバイスが生体適合膜複合材料の円筒形管の形成に基づいているという点において、先に説明したカプセル化デバイス(すなわち実施例1~6中の細胞カプセル化デバイス)とは異なっている。
各デバイス中で使用される補強用構成要素を除いて、同一の細胞カプセル化デバイスを創出した。
実施例7により説明されている通りに、2つのカプセル化デバイス(8Bおよび8C)を構築した。これらのデバイスの各々において、追加の外部補強用構成要素を追加し、この追加の補強用構成要素の影響を、対照としての実施例7で説明されたデバイス7Aと比較した。
管腔内部に追加の内部補強用構成要素を付加する点を除いて、実施例7で説明されている通りにカプセル化デバイス(9B)を構築した。この追加の内部補強用構成要素の影響を、対照としての実施例7で説明されたデバイス7Aと比較した。
