用語「「ストリンジェントな条件」は、ハイブリダイゼーションおよびそれにひきつづく洗浄(washing)の条件に該当し、それを当業者では、従来「ストリンジェント」と呼ばれる。Ausubelら、Current Protocols in Molecular Biology、グリーン・パブリケーションズ・アンド・ウイリー・インターサイエンス、ニューヨーク州ニューヨーク、1987-1995;Sambrookら、Molecular Cloning:A Laboratory Manual、コールド・スプリング・ハーバー・ラボラトリー、ニューヨーク州コールド・スプリング・ハーバー、1989年を参照。

HGFを介した運動性およびCXCR4が増大されることは、損傷を受けた肝臓へのヒトCD34+前駆細胞の遊走を仲介する。
臍帯血のCD34+濃縮細胞を、サイトカインの非存在下、またはCXCR4発現およびSDF−1依存性遊走[Peled(1999年)Science 283巻:845−848頁]を誘導することが知られている、幹細胞因子、HGFまたは両方のサイトカインの組合せの存在下において、40時間培養した。その後細胞を、抗CXCR4および/または抗重合化アクチンとインキュベートし、PBSで頻繁に洗浄し、そしてファロイジン−TRITCおよびヤギ抗ウサギAlexa488とインキュベートした。サイトカインの非存在で培養されたCD34+細胞は、丸い形態を維持する一方で、SCFで培養した細胞は広がっており、そして分極していた。興味深くは、HGFは単独で、細胞表面からアクチンをベースとする突起部の形成を誘導し、そしてSCFとHGFの組合せは、SCFまたはHGF単独で観察されるもの(データは示されず)と異なる表現型であるラメリポジウム形成(lamellipodia formation)を促進した。最も重要なことに、これらの細胞骨格再編成は、CXCR4アップレギュレーション(図1A)およびSDF−1に対し機能的に増強された走化性応答(図1B)と関連があった。HGFは、ヒト前駆体単独の走化性を誘導しなかった(データは示されず)。しかし、HGFは、ヒト前駆体の運動性を増大させ、そしてSCFと相乗作用して、CXCR4発現およびSDF−1で誘導される方向性遊走(directional migration)の両方を可能とした。
照射は、肝臓および骨髄でのHGFをアップレギュレートする
移植前に使用され、そしてSDF−1のような様々なサイトカインをアップレギュレートすることが知られている照射が、肝臓そして骨髄でのHGFのアップレギュレーションを誘導しうるかを探索した。
HGFはSCFと相乗作用して、臍帯血のCD34+細胞の再構築能力を増大させる。
HGFは、CCl4損傷に続いて、SDF−1に向かって遊走する骨髄細胞の能力、および前駆細胞可動化の速度を増大させる。
