Description
本開示の理解を容易にするために、本明細書で使用する用語について以下の定義を設ける。
膵臓癌患者の末梢血液からセプラーゼ(陽性)およびEpCAM(陽性)循環腫瘍細胞(CTC)の選択
以下の臨床測定は、承認されたIRB(ノースカロライナ大学チャペルヒル、ラインバーガー癌センター)からの認定を得たものである。これらの測定は、本発明の実施形態を説明する意図であり、本発明の範囲を限定する意図ではない。本発明は、全ての腺癌または固形腫瘍を包含する意図である。
セプラーゼおよびEpCAM陽性細胞を選択するために使用されるCTCマイクロチップは、熱可塑性に作製された(環状オレフィンコポリマーCOCまたはポリ(メチルメタクリレート)PMMA)。CTCマイクロチップは、共通の1つの入口から延伸し共通の1つの出口へと流れ出る約50個の正弦曲線状のチャネルから成る構造により構成される(Adams et al.,Highly Efficient Circulating Tumor Cell Isolation form Whole Blood and Label−Free Enumeration Using Polymer−based Microfluidics with an Integrated Conductivity Sensor,Journal of the American Chemical Society,139(2008)8633−8641参照)。正弦曲線状チャネルの幅は30μmで深さは150μmである。
様々な癌患者の末梢血液のセプラーゼ(陽性)およびEpCAM(陽性)CTCの比率の決定
CTCマイクロ流体チップをCOC基板内に作製した。チップの設計は26.3×20.5mmのフットプリント、入口および出口連通チャネル(長さ20.5mm、幅400μm、深さ150μm)、そして該チャネルに接続する50個の曲線状の一連のチャネルから構成され、これらが集合して細胞選択用の床を形成している。図1は、CTC選択チップの設計を示す。曲線状の選択チャネルは、それぞれ、長さ30.6mm、深さ150μm、幅25μmであった。CTC選択床の表面積は596mm2(チャネル当たり11mm2)で、連通チャネル内におけるその表面積は45.1mm2であった。チップの全容量は9.4μL(138nL/チャネル)で、連通チャネルの容量は2.5μLであった。
セプラーゼ標的親和性試薬により捕捉されたCTCの発現解析
本明細書に記載の方法を使用して、インピーダンス検出(染色は行わない)を介してCTCを捕捉、放出、計数し、マイクロチューブに回収した。回収したCTCの回転をスピンダウンし、市販のCell−to−CT(商標)キット(Life Technologies,Grand Island,N,Y)の溶解液を20μL以下で用いて溶解した。Cell−to−CT(商標)技術により、RNAを単離または精製することなく、10〜105個の細胞の溶解物の逆転写が可能になる。RNA単離工程を排除することで、細胞の遺伝子発現解析を実質的に促進し簡略化する。代替として、CTCの溶解およびRNAの単離をCTC捕捉床を用いて直接行った。これは、FAPαおよびEpCAMを施し直列に接続された別のチップセットを用いて免疫染色により細胞を計数しそれらの表現型の特徴付けをする際に実施してもよい。
