继转移注入骨髓50 - 100ul使用胰岛素注射器在第3-7天2-4次，最后的捐助到主机1:1的比例，新生儿。瞄准注射部位下方的胸骨和肋骨，但上面的肠道和胃。远远不够插入针穿透腹膜，小心不要刺穿隔膜。骨髓注射过程中失去一些，这并非罕见。您可以通过放松对你的小狗抓地力的损失，为你注入，让皮肤扩大，然后，慢慢消除针。 剖析胸腺通过中线切口，剪开或撕开皮肤?...

双光子成像在胸腺，使我们能够在生活，完整的器官胸腺内选择事件背后的相互作用和迁移研究。

in situ imaging of the mouse thymus using 2-photon microscopy

双光子显微镜（TPM），让我们深入到胸腺的图像和文件胸腺发展的重要事件。我们要按照个人在人群的胸腺细胞迁移，产生不到一％的胸腺细胞从捐赠者是一个无处不在表达荧光蛋白的转基因的派生的新生儿的嵌合体。为了产生这些部分造血嵌合体，新生儿收件人注入骨髓岁之间的3-7天。 4-6周后，小鼠牺牲和胸腺是仔细解剖和bissected维护将成像的组织架构。胸腺是由TPM到盖玻片粘在准备前体内成像。胸腺是保持在成像的DMEM无酚红灌注95％的氧气和5％的二氧化碳，并加​​热到37 ° C。使用这种方法，我们可以研究为一个多元化的T细胞剧目的产生所需的事件。
