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.

In this video, we establish an ex vivo omental organ culture overlaid with GFP-expressing ovarian cancer cells to study ovarian cancer colonization within the omental explant. This protocol analyzes immune cell structures within the omentum known as milky spots that promote metastases.

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University In the back of everyone's eye is a small piece of neural tissue called the retina. The retina has photosensitive cells that respond to stimulation by light. The responses of these cells are sent into the brain through the optic nerve, a bundle of neural fibers. In each retina there is a place somewhere in the periphery where the outputs from retinal cells collect and the bundled optic nerve exits to the brain. At that location,...

This protocol introduces a light-spot assay to investigate Drosophila larval phototactic behavior. In this assay, a light spot is generated as light stimulation, and the process of larval light avoidance is recorded by an infrared light-based imaging system.
FAQs
Small, permeable blood vessels provide an interface between the peritoneal cavity and local immune-cell aggregates. Fluid, cells, and particulate material can pass into this environment, where macrophages, lymphocytes, and other immune cells interact with incoming material. In cancer research, this access is important for examining how tumor cells encounter immune defenses before establishing within the omentum.
Macrophages, lymphocytes, and other immune cells contribute to the cellular composition examined in Milky Spot Analysis. Their presence and arrangement can be assessed alongside milky spot structure to investigate tumor–immune interactions. Comparing cellular composition across samples may help clarify how local immune features relate to tumor-cell access, persistence, or colonization in the omentum.
Each measurement captures a different structural feature of the omental immune landscape. Milky spot number indicates abundance, size describes the extent of individual structures, and distribution shows their spatial pattern. Evaluating these variables together gives a more informative view of how the omentum is organized and supports analysis of changes associated with peritoneal metastasis.
Microscopy and quantitative measurements can connect tumor-cell location with milky spot characteristics, including number, size, distribution, and cellular composition. This approach helps investigators examine whether tumor cells are positioned near these immune structures and how local immune features may accompany omental colonization. The resulting observations support studies of tumor access, tumor–immune interactions, and abdominal dissemination.
A typical workflow uses microscopy, staining, and quantitative analysis of omental milky spots. Imaging documents the structures, staining distinguishes relevant cellular or tissue features, and measurements capture number, size, distribution, or composition. Together, these steps convert visual observations into analyzable data for comparing omental immune organization and tumor-associated changes.
The analysis can provide measurements of milky spot abundance, dimensions, spatial distribution, and cellular composition. These outcomes allow researchers to characterize the omental environment in studies of peritoneal metastasis and to examine relationships between immune structures and tumor cells. Such data can also support evaluation of therapeutic strategies aimed at limiting abdominal tumor dissemination.
