本発明のポリマー構築物は、例示的なポリマーとしてコラーゲンを使用して以下のように説明される。しかしながら、本明細書に記載されるポリマーなどのコラーゲン以外のポリマーをコラーゲンに代わって利用できることを理解されたい。したがって、例示的な生体適合性コラーゲン複合体は、たとえば、創面パッチ、筋肉もしくは臓器パッチ、心臓パッチ、ヘルニアパッチ、皮膚パッチ、熱傷処置パッチ、および皮膚/組織修復パッチなどのパッチ;カフ;血管(動脈、静脈など)修復材料;弁置換材料または弁修復材料;自己移植材料:羊膜および絨毛膜などの同種異系移植材料;異種移植片物質;神経ガイド;チューブ;癒着を予防または阻害するための修復中の腱周囲に存在し得るスリーブなどの腱スリーブ;抗菌剤を送達するための留置チューブ;リンパ管、肝管、すい管、および胆嚢管などの管;尿管および尿道管などの管;コラーゲン線維;コラーゲンゲル;縫合糸;コード;ねじり状コード;靭帯および/もしくは腱の人工器官;ケーブル;組紐;リボン;ステープル;リベット;スポンジなどの形状で形成できる。装置のさらなる例および説明は、米国特許第7,901,455号;米国特許出願公開公報第2008/0161917号、第2008/018893号、第2008/0200992号、第2009/0216233号、第2009/0287308号、第2010/0094318号、および第2010/0094404号;米国仮特許出願第13/153,665号、および第13/105,353号;および米国仮特許出願第61/450,179号に記載されており、これらは参照として本明細書中に援用される。

実施例1‐コラーゲン‐複合体の調製
(A)商業的に入手可能な2,3−ジヒドロキシ安息香酸(10mmol)を、従来の方法により対応するカルボン酸メチルに変換する。メチル2,3−ジヒドロキシベンゾエートのヒドロキシル基は、生成した酸を除去する過剰量の炭酸カリウムの存在下で、アセトンまたはN,N−ジメチルホルムアミド中で少なくとも2当量のベンジルブロミドとの反応により、対応するベンジルエーテルに変換することにより保護される。結果として得られるメチル2,3−ジベンジルオキシベンゾエートを、加水分解し、この場合従来の技術を使用したペンタフルオロフェニルである対応する活性化エステルに変換する。
微粒子化した粒子を生成するために本明細書中で使用される羊膜/絨毛膜組織移植片を、米国特許出願第2008/0046095号に記載される工程により作製した。この文献は全体が本明細書中参照として援用される。組織移植片(4cm×3cm)および2つの9.5mmのスチール研磨ボールを50mlのバイアルに入れて、その後バイアルを密封した。バイアルをクライオブロック(Cryo−block)に置き、クライオブロックをクライオラック(Cryo−rack)に入れた。クライオラックを、液体窒素の入ったデュワーフラスコの中に入れた。組織試料を、30〜60分ほどの間気相冷却に供した。クライオラックをデュワーフラスコから取り外し、クライオブロックをクライオラックから取り外した。クライオブロックをグラインダー(Grinder)(SPEX Sample Prep GenoGrinder 2010)の中に置き、1,500rpm、20分間に設定した。20分間経過した後、微粒子化を確実にするため組織を検査した。必要な場合、組織を再びデュワーフラスコの中に30〜60分間入れ直し、グラインダーにさらに20分間移して微粒子化を十分に確実なものとした。組織が十分に微粒子化された後、米国の規格のASTMふるいのシリーズを使用して分類した。このふるいを、以下の順序:355μm、300μm、250μm、150μm、および125μmで配置した。微粒子化した材料、50mlのバイアルから355μmのふるいに移動させた。微粒子化した粒子を完全に分離するために、各ふるいを個々に撹拌した。微粒子化した粒子が、ふるいを使用して効率的に分離された後、355μm、300μm、250μm、150μm、および125μmの大きさの粒子を有する微粒子化した粒子を、別々のバイアルに集めた。
本明細書に記載される化合物、組成物、および方法に、様々な改変および変形を行うことができる。本明細書に記載される化合物、組成物、および方法の他の態様は、本明細書に開示される化合物、組成物、および方法の明細書および実施を考慮することから明らかである。本明細書および実施例は例示的なものと考えられると意図される。
EpiFix(登録商標)がヒトのMSCの遊走を誘導するか否かを判定するために、ヒトの間葉系幹細胞(ヒトMSC)を、EpiFix(登録商標)試料の存在下で、細胞培養において評価した。EpiFix(登録商標)は、上皮層がインタクトである羊膜および絨毛膜の層である。
標準的な遊走アッセイを、インサートの底部に孔8μmのメンブレンフィルターを備える24ウェルの細胞培養インサートで実施した(図3参照、BD Biosciences)。実験を開始する24時間前に、ヒトのMSC(1つのドナー、3継代)を無血清培地中で培養して、PBS中、5μg/mlのフィブロネクチン300μlを、各細胞培養インサートの中に入れて、細胞培養インサートの表面へフィブロネクチンを一晩かけて吸着させた。
最小のEpiFix(登録商標)試料を含む低の群(直径1.5mmのディスク)は、無血清陰性対照と有意差がなかった(図4の棒グラフ参照)。中の群(直径4mmのディスク)および高の群(12×13mm平方、3〜4mm平方の断片に調節)はいずれも、無血清対照よりも統計学的に高く(対照と比較して約60%および75%遊走、図4参照)、EpiFix(登録商標)が細胞の遊走を刺激したことを示した。高の群は、中の群と有意差はなかった。この結果から、EpiFix(登録商標)製品は、ヒトの間葉系幹細胞を誘引する1つ以上の因子を含むことが示される。
正常なマウスに植え込まれたEpiFix(登録商標)が、幹細胞/前駆細胞、主にマウスの造血幹細胞(HSC)およびマウスの間葉系幹細胞(マウスのMSC)の動員をもたらすか否かを決定するための試験を行った。
6人のドナー由来のEpiFix(登録商標)製品を、正常なマウスに植え込むために使用した。5×5mm平方のEpiFix(登録商標)を、4ヶ月齢のFVB/NJマウス(約23.50g〜約30gの体重)の皮下に手術により植え込んだ。時点ごとに試料当たり4匹のマウスに植え込んだ。この時点は、3日目、7日目、14日目、および28日目であった。陰性対照は、正常な皮膚および偽手術を行ったマウス(外科的に切開したが植え込みは行わなかった)であった。脱細胞化した真皮基質(無細胞皮膚基質;ADM)を、比較インプラント(I型コラーゲン、サイトカインなし)として使用した。インプラントおよびその上の皮膚を、蛍光活性化セルソーティング(FACS)のために収集した。
マウスのHSCは、EpiFix(登録商標)植え込み後7、14、および28日目で陰性対照と比較して著しく増加した(図5A参照)。マウスのHSCは、ADMと比較して28日目でEpiFix(登録商標)試料において有意に増加したままであった。
フローサイトメトリーおよび免疫組織化学的検査を使用して、マウスのEpiFix(登録商標)植え込み部位に動員される幹細胞を特徴付けるための試験を行った。
滅菌のPurion(登録商標)で処理した5×5mm平方パッチのEpiFix(登録商標)を、16匹の4ヶ月齢のFVB/NJマウスの背部皮膚切開を介して皮下に植え込んだ。同一の皮膚切開を、対照処置(偽処置)として機能するように別の16匹のマウスに行った。コラーゲン足場と比較するために、脱細胞化したヒトの真皮(無細胞性皮膚基質、ADM)の5×5mm平方のパッチを、16匹のマウスの背部皮下に植え込んだ。手術を行わなかった(un−operated)マウスを、解析のため「正常な」背部皮膚の供給源として使用した。
FACS解析からの代表的なデータを図6Aに示す。左側のパネルは、試料中の総細胞数を示す。中央のパネルは、CD45陽性細胞数を示す(赤色のボックス中)。右側のパネルは、Sca−1陽性細胞の数を示す(赤色のボックス中)。CD45およびSca−1は、造血幹細胞の特異的マーカーである。
上述の様々な生体材料または組織移植片を、従来のアミド形成条件下で、少なくとも30個のドーパミンの等価物と混合して、生体材料または組織と結合した複数の保護されたキレート部分を提供した。ドーパミンの窒素は、羊膜のコラーゲンの多くのカルボン酸基と反応してカルボジアミド結合を形成する。
上述の乾燥した非架橋型組織‐キレーター複合体を、1%(w/v)シスジアミノPt(II)のジアクア塩の水溶液中で、室温で16時間インキュベートした。次いで移植片を脱イオン水で洗浄し、乾燥した。複合体中の白金含有量を、たとえば誘導結合プラズマ質量分析法(ICP−MS)により測定する。結果を、μg/gとして表し、これは、百万分の一(ppm)に相当する。
可変真空圧力および乾燥ボードの穴の大きさの試験
この試験は、望ましい組織の美観を得るための、真空圧力の作動および乾燥ボードの穴の大きさを例証するものである。
