有効な治療戦略を開発しようとすると、がんの生物学者は、重要な課題に直面しています。確立された癌細胞に発達中の薬剤のテストラインが正確にPDXモデルでインビボ応答およびin vivo実験に反映しないことができ、労働集約的で極めて高価である。上記の、ex vivoでの適用は、原発性腫瘍患者14の技術は、15は、現在確立された癌細胞株および患者由来の...

有効な癌治療を開発することが極めて困難であることが証明された。癌細胞株および腫瘍外植-ならびに異種移植片は、半世紀以上の1,2,3のための癌研究に使用されている。現在までに、両方の確立された癌細胞株および患者由来の異種移植片（PDX）における薬剤感受性と耐性の分子分析が不可欠である。しかし、確立された癌細胞株における化合物の試験は、多くの場合、 インビボでの有効性の予測ではなく、特にPDXモデルにおいて、動物においてin vivo研究対応する、非常に高価であり、時間がかかる。これらのモデル系、腫瘍の進行および治療戦略に応じて、ネイティブの微小環境の影響に通知することができない、すなわちの限界は、これらの分析を補完するための追加の方法を開発する研究分野をリードしてきました。最近の中でも、高まり注意が患者TUM のex vivo解析に向けて注目されている癌治療反応は、癌細胞の固有の分子組成に排他的ではなく、むしろ大幅に伝統的な培養法によって再現したことができない腫瘍細胞の微小環境6,7機能によって影響されることにより、より深く理解するか、外植片4、5 /またはPDX。上記の文脈におけるエクスビボ分析が（ すなわち 、隣接する周囲の腫瘍細胞の微小環境の影響が）、むしろ、携帯分離株8,9 のex vivo分析よりも、生存可能な原発腫瘍/転移切片の評価を意味する。 私たちは忠実に、応答（IC 50）に通知するオフターゲット効果と分子を可能にし、患者の原発腫瘍と関連する転移（ すなわち 、リンパ節）の両方のex vivo手法（ すなわち 、精密スライスされた新鮮な組織切片）でここに報告抵抗とフィードバックのメカニズムの解析。さらに、therapeの相関分析バイオマーカーおよび遺伝子発現プロファイルに対するUTIC感受性/抵抗性（ すなわち 、高い薬物応答が特定の生物学的プロフィールを有する患者と一致する）関心のある試験薬に応答する可能性が高い患者を同定するための努力を行うことができる。マルチパラメータ方式でex vivoでの手法や評価の適用は、患者の選択と臨床転帰の全体的な改善に向けた動きである。 エクスビボ治療応答解析は、癌治療薬の前臨床および臨床開発における標準的なツールになる可能性があり、治療上の開発戦略における個別化医療のアプローチに向けたステップとして想定される。

ex vivo treatment response of primary tumors and/or associated metastases for preclinical and clinical development of therapeutics

The molecular analysis of established cancer cell lines has been the mainstay of cancer research for the past several decades. Cell culture provides both direct and rapid analysis of therapeutic sensitivity and resistance. However, recent evidence suggests that therapeutic response is not exclusive to the inherent molecular composition of cancer cells but rather is greatly influenced by the tumor cell microenvironment, a feature that cannot be recapitulated by traditional culturing methods. Even implementation of tumor xenografts, though providing a wealth of information on drug delivery/efficacy, cannot capture the tumor cell/microenvironment crosstalk (i.e., soluble factors) that occurs within human tumors and greatly impacts tumor response. To this extent, we have developed an ex vivo (fresh tissue sectioning) technique which allows for the direct assessment of treatment response for preclinical and clinical therapeutics development. This technique maintains tissue integrity and cellular architecture within the tumor cell/microenvironment context throughout treatment response providing a more precise means to assess drug efficacy.
