このhACL/2D足場研究の主な目的は、部分的なACLの涙の主要な修理を強化するために、パッチで得られた細胞を使用することでした。部分的なACLの涙の非手術管理が固定化、ブレーシング、進歩的リハビリテーションプログラム、および定期的なフォローアップの評価13,16,17の短期間を含むことができる。しかし、多くの研究がスポーツ選手での保存的治療が不十分な結果、失敗と関​?...

前十字靱帯（ACL）は膝の一般負傷した関節内靭帯である。約20万（ACL）の傷害は、米国で毎年報告されています。整形外科再建手術1,2,3,4のACL損傷OPTを経験した患者の75％以上。外科的介入は、しばしば本質的に治癒不良の可能性3に示されている。 ACL再建は、典型的には、自家移植片又は同種移植腱によって達成される。自家移植と同種移植片は、高い成功率を誇るように復興のためのゴールドスタンダードを表し、一次縫合の修理、他の治療オプションは、最大で94％で5,6,7の故障率を示している。 ACLの部分的な涙はすべてのACLの涙8の28％、10％に相当する。プロスペクティブ研究では、ノイスら 、よりACLの半分以上の部分に影響を与える涙を有する患者の50％が後、非ACL不全を完了するために進行していると推定手術治療9。他の研究では、持続的な不安定性を報告し、その損傷前の活動レベル9,10,11,12,13に戻ることができた患者の30％未満で機能の低下。治療の選択肢は限られており、保守的な様式、残りのACLの熱収縮、またはACL再建が含まれています。最近では、拡張現実、一次修理に対する関心が高まっています。これらの技術は、一次縫合糸修復14を強化するために生物学的製剤を使用しています。最近の研究では、間葉系様HACLを収穫しようとした31,32、移植の制限を回避するために幹細胞を誘導されたが、これらの細胞の妥当性と有効性はまだ不明です。組織工学用途のための理想的な細胞源は、非mesechymal HACLは、線維芽細胞に由来すると思われる。 現在の研究は、適切なマトリックス材料および操作された足場のための細胞源の同定に焦点を当てている。引き裂かれたACLは、suとして廃棄されることが標準的な手順である再建手術中rgical廃棄物は、しかし、この損傷を受けた靭帯は、ACL置換を設計し、理想的な組織を開発し、強化するために必要な細胞の取得質源であってもよい。私たちの研究室では、これらを採取HACL由来細胞のin vitroでの拡大のためのプロトコルを開発しました。 HACL由来細胞を注入された設計の2Dマトリックスを使用して、我々は潜在的に部分的なACLの修復を増強し、引き裂かれた靭帯を強化する可能性がパッチを設計しました。

surgical retrieval, isolation and in vitro expansion of human anterior cruciate ligament-derived cells for tissue engineering applications

ACLに損傷がアクティブの個体において一般的に発生する問題です。機能性と安定性を損なう生体力学的な欠陥は、この関節膝靭帯リードのさえ部分的な涙。熱修正、シングルバンドルの修復、完全な復興、およびネイティブ靭帯の損傷部分の再構築：部分的なACLの涙の治療のための現在のオプションは保存療法、保守的な経営陣からのような複数の外科オプションの範囲。いくつかの研究は、もしあれば、一貫して優れていると管理のための任意の単一の方法を実証しており、多くの場合、患者は、永続的な不安定性および他の併存疾患を実証し続ける。 本研究の目的は、部分的に引き裂かれたACLの修復に実施することができる組織工学パッチの開発に利用するための潜在的な細胞源を同定することである。新規プロトコルはpatieに由来する細胞の拡大のために開発されましたACL再建を受けてNTS。細胞を単離するために、ACL再建中に得られたミンチHACL組織をコラゲナーゼ溶液中で消化した。膨張は、10％ウシ胎児血清（FBS）を補充したDMEM/F12培地および1％ペニシリン/ストレプトマイシン（P / S）を用いて行った。次いで、細胞をDMSO、FBSおよび拡張培地からなる凍結培地中に-80℃で、または液体窒素中で保存した。解凍後、HACL由来細胞は、次いで、組織工学的足場、PLAGA（ポリ乳酸 - コ - グリコール酸）および対照組織培養ポリスチレン（TCPS）上に播種した。 7日後、SEMを制御TCPSに対するPLAGAに対する細胞接着性を比較した。細胞形態は、免疫蛍光染色を用いて評価した。 SEM（走査型電子顕微鏡）顕微鏡写真は、細胞が成長し、PLAGAおよびTCPS両面に付着し、7日目で全面にコンフルエントことを明らかにした。免疫蛍光染色は、通常、非ストレス形態学を示した両面にアルミニウムパターン。この手法は、ACLの再生·復興への応用が期待されている。
