Vi beskriver en enkel och kostnadseffektiv metod för att isolera stora mängder av murina monocyter från benmärg. I jämförelse med andra protokoll som använder perifert blod, vilket erhåller monocyt avkastning 5 av 1,4 x10 6, har vi möjlighet att få högre avkastning på 11 x 10 6 ± 3 x 10 6 monocyter från en enda donator mus. När man överväger utmaningar med denna metod är det viktigt att nämna risken för förorening vid arbete un...

The isolation of monocytes is important and critical for many in vitro and in vivo studies. These cells are targets for diseases such as peripheral arterial disease, coronary heart disease, or other ischemic diseases, since collateral vessel growth is strongly driven by local inflammation. Inflammatory responses include endothelial activation and local recruitment of leukocytes, mainly monocytes, which then mature to macrophages and create a highly arteriogenic environment by secreting multiple growth factors to induce the remodeling of an arteriole into a functional collateral artery1-3. Monocytes also mature to dendritic cells, which are frequently used for immunological studies4,5 and cancer research6,7.
Problematic in the approach for monocyte isolation from peripheral blood8 is the high number of donor animals needed to produce a sufficient amount of monocytes for most analyses. Former protocols describe methods such as density gradient centrifugation and cell depletion via MACS9 when isolating monocytes; however, these techniques can alter the characteristics and functionality of monocytes which can lead to difficulties in interpretation10,11. Moreover, these methods are difficult and can reduce experimental reproducibility.
Our aim with this protocol is to provide a simple and cost effective method to generate large amounts of bone marrow-derived monocytes. Due to the high cell yield of 11 x 106 &#177; 3 x 106 cells obtained by this protocol, we can substantially reduce the number of mice required during the isolation of bone marrow-derived monocytes. The procedure can be completed within a minimal amount of time, and without using expensive and complicated techniques as referenced above. Here, we extract monocytes from native bone marrow suspension of donor mice, cultivate the suspension on ultralow attachment plates, and supplement the solution with 20 ng/ml M-CFS. On day 5 of incubation, cells are harvested and characterized to confirm functional and phenotypic properties.
For experiments in the field of arteriogenesis, intravenous transplantation of these bone marrow-derived monocytes into mice is an effective method of systemic drug delivery, which can be combined with femoral artery ligation in common peripheral arterial disease models.

isolation and intravenous injection of murine bone marrow derived monocytes

As a subtype of leukocytes and progenitors of macrophages, monocytes are involved in many important processes of organisms and are often the subject of various fields in biomedical science. The method described below is a simple and effective way to isolate murine monocytes from heterogeneous bone marrow.
Bone marrow from the femur and tibia of Balb/c mice is harvested by flushing with phosphate buffered saline (PBS). Cell suspension is supplemented with macrophage-colony stimulating factor (M-CSF) and cultured on ultra-low attachment surfaces to avoid adhesion-triggered differentiation of monocytes. The properties and differentiation of monocytes are characterized at various intervals. Fluorescence activated cell sorting (FACS), with markers like CD11b, CD115, and F4/80, is used for phenotyping. At the end of cultivation, the suspension consists of 45%&#177; 12% monocytes. By removing adhesive macrophages, the purity can be raised up to 86%&#177; 6%. After the isolation, monocytes can be utilized in various ways, and one of the most effective and common methods for in vivo delivery is intravenous tail vein injection. 
This technique of isolation and application is important for mouse model studies, especially in the fields of inflammation or immunology. Monocytes can also be used therapeutically in mouse disease models.
