non-invasive imaging of leukocyte homing and migration in vivo

双光子显微镜（2P）是一种高分辨率的成像技术，已被广泛生物学家适应。 2P显微镜的价值是，它提供了丰富的时空内完整的组织和细胞在活体小鼠行为的信息。白细胞招聘中起着重要的作用在宿主防御感染和未选中时，可以促进炎症和自身免疫性疾病。研究在体内的白细胞招聘是在技术上具有挑战性，因为细胞正在迅速在位于深内光散射组织的船只。迄今为止，大多数活体成像研究需要手术的准备，暴露的血管和组织。为了避免手术本身引起的组织损伤和炎症，在这里，我们描述了一种非侵入性的单细胞成像的方法，可用于研究白细胞贩运鼠标脚垫和指骨。我们讨论了我们的2P成像准备的技术方面和读者穿行典型的从最初的成立，以执行和数据采集的实验。
