This study was supported and funded by the Avenir Foundation (Fondation de l'Avenir, 255 rue de Vaugirard, 75719 Paris cedex 15, Paris, France). This study would never have been conducted without the precious help of the veterinary team of the Laboratory of Biosurgical Research from the Alain Carpentier Foundation.

表在食道腫瘍の管理は、新しい内視鏡技術の開発と変更されました。今日では、内視鏡的切除が第一選択治療です。実際に、同等の腫瘍学的結果を1、2、3で手術より低い罹患率および死亡率と関連しています。内視鏡的粘膜切除術（EMR）と内視鏡的粘膜下層切除（ESD）は、最も広く使用されている技術です。拡張された表在性腫瘍の場合には、ESDが好ましいです。 EMRに比べて、ESDに関わらず、病変の大きさの、 ブロック切除専用でき、4、5、6を形作ります。 ESDの主な遅延合併症は、一般的切除後1および2週間の間に発生する食道狭窄形成、です。最近公表された研究は、狭窄形成が相関することを示しています切除のサイズ。日本内視鏡学会は、それらが例の90％以上に狭窄の開発に関連付けられており、厳しい送りトラブルや生活の質の主要な劣化を担当されているので、食道周囲の3/4よりも大きなサイズのESDを回避することをお勧めします。 食道狭窄の予防は依然として厳しいです。狭窄の形成に関与する機構は、部分的にしか知られています。狭窄形成つの異なるメカニズムの会合に起因すると思われる：（1）プロ炎症性細胞の動員、（2）過剰な線維症の開発7。いくつかの予防的治療法が提案されています。しかし、結果は、ほとんど利益と重篤な副作用8,9と、不十分でした。最近、日本のチーム、大木ら。 、esophに自己口腔粘膜細胞の単層細胞シートを移植することを提案ageal傷跡。移植はESD 10、11の直後に行きました。彼らは、最初のイヌのモデルにした後、患者に、この革新的なアプローチの有効性を実証しました。 脂肪組織由来間質細胞（ADSCを）は、再生医療に期待されています。いくつかの分野におけるそれらのアプリケーションは、特に創傷治癒過程で、興味深い結果を示しています。細胞は、容易に分離され、間葉系と非間葉系統12、13、14への抗炎症性、局所免疫調節作用、血管新生の誘導、および分化能力に関連付けられているためADSC療法は、いくつかの利点を提供しています。 以前の研究では、我々のチームは、食道狭窄prevをダブルADSC-シート内視鏡移植の有効性を実証しました豚モデル15内の拡張ESD後ention。この記事では、ADSC-枚構成と内視鏡的移植技術のレポートが提示されています。

adsc-sheet transplantation to prevent stricture after extended esophageal endoscopic submucosal dissection

過去数年間において、細胞シート構築物は、特に再建手術の手順については、再生医療の幅広い関心に拍車をかけました。様々な生体材料と脂肪組織由来間質細胞（ADSCを）を組み合わせ多様な技術の開発は、骨、軟骨、およびげっ歯類、ブタ、またはヒトのADSCからの脂肪組織などの組織工学代用、多数のタイプの建設につながっています。拡張食道内視鏡的粘膜下層剥離術（ESD）は、食道狭窄形成を担当しています。狭窄の予防は利用できませ効率的な治療法と、依然として厳しいです。以前の研究では、イヌのモデルおよびヒトにおいて粘膜細胞シート移植の有効性を報告しました。 ADSCを間葉系と非間葉系統に抗炎症性、局所免疫調節作用、血管新生の誘導、および分化能力を起因しています。この最初の研究では、内視鏡TRAを説明します豚のモデルに食道狭窄を防ぐために、ADSCの組織工学構築物のnsplantation。 ADSC構築物は、紙支持膜上に互いの上に積層2同種ADSCシートから構成されました。 ADSCを、プローブベースの共焦点レーザーendomicroscopy（PCLE）監視できるようにPKH67蛍光色素で標識しました。移植の日に、5-CMおよび食道狭窄を誘導することが知られている半円周ESDを行いました。動物はすぐに内視鏡4 ADSC構築物で移植しました。 ADSC構築物の完全な接着が穏やかアプリケーションの10分後に得ました。動物は、すべての動物が正常に移植された28日目に屠殺しました。移植は正PCLE評価で3日目に確認されました。移植された動物と比較して、対照動物には、主要な線維性組織の発達と、より頻繁に消化トラブル重度狭窄を発症し、体重増加を減少させました。 allogeniの我々のモデルでは、移植C二重細胞シートで組織のADSCは、拡張ESD後に成功したと強く下部食道狭窄率に関連付けられていました。

ADSCシートを得るためのADSCの培養及び手順は、図1に示されています。 図2はその紙支持体膜上に互いの上に層状に2 ADSCシートで構成され、移植片の構成を示しています。 ADSCをは、以前PCLEと生体内移植片の監視にできるようにPKH67蛍光色素で標識しました。 図3は、5-cmであり、半周食道傷跡が得られ、拡張された食?...
