non-invasive imaging of leukocyte homing and migration in vivo

二光子（2P）顕微鏡は、広く生物学者によって適応された高分解能のイメージング技術です。 2P顕微鏡の値は、それがそのまま組織内および生きたマウスの細胞の挙動に関する豊富な時空間情報を提供することです。白血球の動員が感染し、このチェックボックスをオフにした場合に対する宿主防御において重要な役割を果たし、炎症や自己免疫疾患に貢献することができます。細胞は光散乱の組織内に深くある血管内に急速に移動しているので、 生体内で白血球動員を研究することは技術的に困難である。これまでに、ほとんどの生体内イメージング研究では、血管や組織を露出させる手術の準備が必要です。手術自体によって誘導される組織の損傷や炎症を避けるために、ここで、我々は、マウスの足蹠とphalanxの複数形で白血球人身売買を研究するために使用できる非侵襲的単一細胞イメージングのアプローチを説明します。私たちは、2Pのイメージングの準備の技術的側面を議論し、実行してデータ収集するための初期設定から典型的な実験を通してリーダーを歩く。
