[Abstract]  

Myeloid progenitors in the bone marrow generate monocytes, macrophages, granulocytes and most dendritic cells. Even though these innate immune cells are part of the same lineage, each cell type plays a specific and critical role in tissue development, host defense and the generation of adaptive immunity. Protocols have been developed in the past to differentiate myeloid cell types from bone marrow cells, enabling functional investigation and furthering our understanding about their contribution to mammalian physiology. In this protocol, we describe a simple and rapid method to isolate monocytes from murine bone marrow, culture them for up to 5 days and lastly, differentiate them into bone marrow derived macrophages (Figure 1).

[摘要]  [摘要]骨髓中的骨髓祖细胞产生单核细胞,巨噬细胞,粒细胞和大多数树突状细胞。即使这些先天免疫细胞是同一谱系的一部分,每种细胞类型在组织发育,宿主防御和适应性免疫的产生中也发挥着特定而关键的作用。过去已经开发出区分骨髓细胞和骨髓细胞的协议,以进行功能研究并加深我们对它们对哺乳动物生理学贡献的理解。在该协议中,我们描述了一种简单快速的方法,可从鼠骨髓中分离单核细胞,将其培养长达5天,最后,将它们分化为源自骨髓的巨噬细胞(图1)。

[Abstract]  Murine pharmacokinetics (PK) represents the absorption, distribution, metabolism, and elimination of drugs from the body, which helps to guide clinical studies, ultimately resulting in more effective drug treatment. The purpose of this protocol is to describe a serial bleeding protocol, obtaining blood samples at six time points from single mouse to yield a complete PK profile. This protocol has proved to be rapid, highly repeatable, and relatively easy to acquire. Comparing with the conventional PK studies, this method not only dramatically reduces animal usage, but also decreases sample variation obtained from different animals. [摘要]  小鼠药代动力学(PK)代表了体内药物的吸收,分布,代谢和消除,这有助于指导临床研究,最终导致更有效的药物治疗。 该方案的目的是描述连续出血方案,在单个小鼠的六个时间点获得血液样品以产生完整的PK谱。 该协议已被证明是快速的,高度可重复的,并且相对容易获得。 与传统的PK研究相比,该方法不仅大大减少了动物的使用,而且减少了从不同动物获得的样本变异。
