We outline a protocol that implements both in vivo and ex vivo approaches to study ovarian cancer colonization of peritoneal adipose tissues, particularly the omentum. Furthermore, we present a protocol to quantitate and analyze immune cell-structures in the omentum known as milky spots, which promote metastases of peritoneal adipose.

The ability of metastatic clones to colonize distant sites depends on their proliferation capacity and/or their ability to survive in the host microenvironment without significant proliferation. Here, we present an animal model that allows quantitative visualization of both types of liver colonization by metastatic clones.
FAQs
These models are valuable because they separate post-dissemination events from invasion and circulation. After cancer cells reach a distant organ, the experimental focus can shift to survival, extravasation, dormancy, adaptation to the local microenvironment, and renewed proliferation. Studying this sequence helps identify which requirements are shared across metastatic sites and which are organ specific, improving interpretation of colonization mechanisms.
Organ-specific requirements reflect the fact that disseminated cells do not encounter identical surroundings in every distant tissue. A metastatic colonization model can therefore examine how local microenvironmental interactions support or restrict adaptation and later tumor growth. This distinction matters because a cell's ability to disseminate does not by itself establish that it can successfully grow at a secondary site.
Animal models, organoid systems, and engineered tissue platforms provide distinct experimental settings for examining metastatic colonization. Together, they allow researchers to study the process across whole-organism, organoid, and engineered-tissue contexts while isolating colonization from earlier disease steps. Using multiple platforms can broaden analysis of organ-specific requirements and the local interactions associated with secondary-tumor growth.
Dormancy is a key state because disseminated cancer cells may survive without immediately producing renewed tumor growth. Metastatic colonization models include dormancy among the sequential events that follow dissemination, allowing researchers to consider why secondary disease may emerge after a delay. This makes the models relevant to therapies intended to prevent recurrence or eliminate dormant cells.
To study colonization specifically, researchers use an experimental system that separates post-dissemination behavior from earlier invasion and circulation. The model then centers on the sequence from tumor-cell survival and extravasation through dormancy, local adaptation, and renewed proliferation. Framing the experiment around these stages helps attribute observed secondary-tumor growth to colonization-related biology rather than preceding steps.
Researchers can use organoid systems and engineered tissue platforms when they want experimental systems focused on metastatic colonization and its local context. These approaches complement animal models by providing additional settings for examining organ-specific requirements, adaptation, and microenvironmental interactions. Their use is especially relevant when the research question concerns how secondary sites support or restrict later tumor growth.
Researchers apply these models to investigate treatment vulnerabilities that appear during secondary-tumor establishment. Because the systems address cancer cells and the microenvironmental interactions that sustain growth, they can support studies of therapies that disrupt those interactions. They also inform strategies aimed at preventing recurrence, eliminating dormant cells, or interrupting the transition from adaptation to renewed proliferation.
