Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”. Morphological Manifestations of Necrosis Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...

This protocol describes a method for the detailed evaluation of leukocyte subsets within the tumor microenvironment in a mouse tumor model. Chemerin-expressing B16 melanoma cells were implanted subcutaneously into syngeneic mice. Cells from the tumor microenvironment were then stained and analyzed by flow cytometry, allowing for detailed leukocyte subset analyses.

This protocol describes a detailed workflow for the generation and ex vivo characterization of oncolytic viruses for expression of immunomodulators, using measles viruses encoding bispecific T cell engagers as an example. Application and adaptation to other vector platforms and transgenes will accelerate the development of novel immunovirotherapeutics for clinical translation.

Source: Chen, Y. et. al., Evaluating Virulence and Pathogenesis of Aeromonas Infection in a Caenorhabditis elegans Model. J. Vis. Exp. (2018)This video demonstrates a muscle necrosis assay in C. elegans (Caenorhabditis elegans) using pathogenic Aeromonas strains. By feeding green fluorescent protein (GFP)-expressing worms on Aeromonas-seeded plates, the assay models bacterial infection and reveals tissue damage through fluorescence imaging. The progressive loss of muscle structure and GFP...

FAQs
The central mechanism is a mismatch between tumor expansion and blood supply. As growth accelerates, inadequate perfusion can produce hypoxia and nutrient depletion, followed by cellular energy failure and loss of membrane integrity. The resulting tissue injury can reveal how aggressively a tumor is behaving, making the extent and distribution of necrosis relevant to cancer research.
Histopathology, imaging, and molecular markers can each help separate viable tumor from damaged tissue, but they examine that distinction through different types of evidence. Histopathology assesses tissue structure, imaging shows tumor regions, and molecular markers provide biological signals. Using these approaches supports more complete characterization of tumor injury.
Loss of membrane integrity is an important endpoint because it reflects severe cellular injury rather than only reduced function. In the progression from hypoxia and nutrient depletion to energy failure, cells may lose the ability to maintain their membranes. Evaluating this damage helps researchers identify areas that are no longer viable.
A basic evaluation workflow begins by selecting a suitable evidence source, such as tissue histopathology, imaging, or molecular markers. Researchers then use that source to identify necrotic areas and distinguish them from viable tumor. The resulting measurement can support analysis of tissue injury, disease progression, tumor characteristics, or treatment response.
Treatment studies use necrosis measurements to determine whether an intervention has damaged cancer cells. Researchers can assess injured tissue alongside the remaining viable tumor, helping them judge treatment response. This makes necrosis evaluation useful for comparing therapeutic effects and supporting the development of new cancer treatments.
In cancer research, these assessments connect tissue-level injury with broader questions about tumor biology, disease progression, aggressiveness, and prognosis. A necrosis measurement can therefore serve more than a descriptive purpose: it helps organize findings about how tumors behave and how they respond to therapy, while supporting studies designed to improve treatment development.
