The peritoneal cavity in mammals contains different immune cell populations crucial for innate immune responses. An efficient isolation method is required for biochemical and functional analyses of these cells. Here we provide a comprehensive method for the isolation of peritoneal cavity cells in the mouse.

Ovarian cancer metastasis is characterized by numerous diffuse intra-peritoneal lesions, such that accurate visual quantitation of tumor burden is challenging. Herein we describe a method for in situ and ex vivo quantitation of metastatic tumor burden using red fluorescent protein (RFP)-labeled tumor cells and optical imaging.

In this video, we describe the procedure for isolating low-density neutrophils, or LDNs, from the peritoneal lavage fluid of a postoperative human patient. The LDNs thus obtained can be used in further downstream experiments to understand their role in tumor growth and progression.
FAQs
Contrast arises because tissue-reactive dyes or histological markers interact differently with surface conditions. Normal mesothelium may produce a pattern distinct from damaged tissue, inflammatory areas, or abnormal cellular deposits. These differences make otherwise subtle changes more apparent, helping an examiner recognize variation across the peritoneal surface and focus attention on regions that may require closer assessment.
The staining response reflects differences in the tissue being examined. Intact mesothelium, damaged areas, inflammation, and abnormal cellular deposits do not interact with markers in the same way, so they can appear visually distinct. This relationship matters because the resulting pattern may connect a surface abnormality with an underlying tissue process rather than merely showing its location.
Visible staining patterns provide a surface-level view that can be compared with microscopic observations from examined tissue. This correlation helps clarify whether an apparent surface change corresponds to damaged tissue, inflammation, or abnormal cellular deposits. In pathology, linking gross appearance with histological findings can improve interpretation of lesion characteristics and support evaluation of disease mechanisms.
A general workflow involves applying an appropriate tissue-reactive dye or histological marker to the peritoneal surface, observing the resulting contrast, and documenting areas with distinctive staining patterns. The examiner can then compare stained regions with visible lesions and, when indicated, direct sampling toward representative areas. Interpretation remains tied to the corresponding pathological and microscopic findings.
Staining can help identify surface regions that differ from surrounding peritoneum, including areas associated with tissue damage, inflammation, or abnormal cellular deposits. Those visual differences may help direct sampling toward more informative sites rather than relying only on an unaided surface inspection. The sampled material can subsequently support microscopic correlation and a more focused assessment of peritoneal disease.
Peritoneal Surface Staining can support assessment of both the character and distribution of peritoneal lesions. Patterns across the surface may show whether abnormalities are localized or more widespread, while comparison with microscopic findings adds pathological context. Its value is therefore complementary: it improves visualization during examination and helps relate surface appearance to disease-related tissue changes.
