1. Cell Preparation
Note: Different cancer cell lines can be used for IIA injection depending on research purposes. We have used breast cancer cell lines MCF7, 4T1, 4T07, MDA-MB-361, MDA-MB-231, MDA-MB-436 and prostate cancer cell line C4-2 in our research. We typically use both GFP- and firefly luciferase-labeled cancer cells for our study and show some data here f...

Although only the iliac artery is the target of injection for cancer cells, we recommend the separation of both iliac vein and artery from surrounding tissues, and to lift them together as a bundle. This is because the vein and artery extensively contact with each other, and the venous vessel wall is thin and is easy to break. Therefore, for a successful injection, it saves time and effort to hold up the two vessels together, although cancer cells are injected only to the artery. A 4-0 silk suture is used to help this pr...

Metastases account for over 90% of deaths caused by solid tumors. Bone is the most common organ affected by metastases of various cancer types, especially breast and prostate cancers. When diagnosed in the clinic, bone metastases usually have already entered advanced stages with either osteolytic or osteoblastic alterations in bone, often accompanied with neurological symptoms.
Previous studies predominantly focused on the overt osteolytic bone metastases1-3, however we currently have limited understanding of micrometastases in bones before the onset of the osteolytic process. This is at least partly due to lack of appropriate experimental models and approaches. Genetically engineered mouse models of breast cancer often metastasize to lungs, but much less efficiently to bones4. Likewise, the orthotopically transplanted tumors rarely develop spontaneous bone metastases, with some bone-tropical 4T1 mammary carcinoma sub-clones and MSP overexpressed PyMT transgenic mouse model as exceptions5-7. Intra-tibial drilling can deliver cancer cells to the bone8-10, but it also incurs damage and inflammation to local tissues. Currently intra-cardiac injection of breast cancer cell lines has been the major approach to investigate bone colonization11-13. However, after cancer cells are introduced into left ventricle only a limited proportion will finally reach bone and bone marrow, making it difficult to track microscopic metastases in a quantifiable fashion.
In this study, we establish a technique, namely intra-iliac artery (IIA) injection14, to selectively deliver cancer cells into hind limb tissues, thereby enriching cancer cells in bone and bone marrow without causing damage to local tissues. Because of the bone specificity, this approach also allows enough time for indolent cancer cells to eventually colonize before the animals succumb to primary tumors or metastases in other vital organs. When combined with a variety of other techniques, such as bioluminescence imaging, immunofluorescence staining and bone histomorphometry, IIA injection is potentially useful for a wide scope of research purposes related to bone metastases, especially to track the progression from single cancer cells to multi-cell micrometastases. In particular, we demonstrated that IIA injection enables us to visualize the interactions between cancer cells and various types of surrounding cells in the bone microenvironment.

intra-iliac artery injection for efficient and selective modeling of microscopic bone metastasis

Intra-iliac artery (IIA) injection is an efficient approach to introduce metastatic lesions of various cancer cells in animals. Compared to the widely used intra-cardiac and intra-tibial injections, IIA injection brings several advantages. First, it can deliver a large quantity of cancer cells specifically to hind limb bones, thereby providing spatiotemporally synchronized early-stage colonization events and allowing robust quantification and swift detection of disseminated tumor cells. Second, it injects cancer cells into the circulation without damaging the local tissues, thereby avoiding inflammatory and wound-healing processes that confound the bone colonization process. Third, IIA injection causes very little metastatic growth in non-bone organs, thereby preventing animals from succumbing to other vital metastases, and allowing continuous monitoring of indolent bone lesions. These advantages are especially useful for the inspection of progression from single cancer cells to multi-cell micrometastases, which has largely been elusive in the past. When combined with cutting-edge approaches of biological imaging and bone histology, IIA injection can be applied to various research purposes related to bone metastases.

Figure 1 illustrates the anatomical location and relationship of common iliac artery (red) and vein (blue).
Figure 2 shows relative position of iliac vessels and nerves under dissection microscopy. As depicted in Figure 2A, the vessels and nerves are right beneath the peritoneal wall and can be revealed after the skin incision is made and the peritoneum is pushed away. The commo...

Intra-iliac Artery Injection for Efficient and Selective Modeling of Microscopic Bone Metastasis

This manuscript provides the detailed procedure of intra-iliac artery (IIA) injection, a technique to deliver cancer cells specifically to hind limb tissues including bones to establish experimental bone metastases. Although initially established with breast tumor models, this protocol can be easily extended to other cancer types.
