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...

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...

Cellular Injury IV: Necrosis

Necrosis is a form of irreversible cell death caused by severe injury such as ischemia, toxins, or trauma. Unlike programmed cell death, it is an uncontrolled, pathological process that typically provokes inflammation in surrounding tissues.Pathophysiologic ChangesNecrosis begins when cells sustain critical damage, leading to swelling of organelles, particularly mitochondria, and rapid ATP depletion. As energy levels decline, membrane ion pumps fail, leading to calcium influx and eventually,...

The primary outcome measure in clinical trials for neuromuscular disorders is generally improved muscle function. Therefore, assessing the effect of potential therapeutic compounds on muscle performance pre clinically in mouse models is of great importance. We here describe several functional tests to address this.
FAQs
Different readouts capture different consequences of cellular damage. Morphology shows visible structural changes, while assays can detect plasma-membrane disruption, leakage of intracellular contents, or altered viability. Using these approaches together provides a more complete evaluation than relying on a single measurement and helps researchers interpret whether observed injury reflects necrotic damage.
The most informative features are changes in cell appearance, loss of plasma-membrane integrity, release of intracellular contents, and reduced cellular viability. These findings represent complementary evidence rather than interchangeable measurements. Considering them together helps distinguish damaged cells from healthy cells and can support comparisons with apoptotic cells when that distinction is relevant.
The distinction depends on comparing morphological observations with measurements of membrane integrity, intracellular-content release, and viability. Necrotic damage is supported when the findings indicate membrane disruption and leakage, whereas interpretation should account for whether the observed pattern differs from apoptotic cells. Combining evidence is therefore important when both forms of cell death may occur.
These conditions represent different sources of tissue or cellular injury, so measurements should be interpreted in relation to the biological challenge being studied. A treatment may alter survival, membrane integrity, or leakage in a pattern that differs from infection or ischemia. Comparing responses across conditions reveals how each stressor changes cellular damage.
A typical evaluation begins with morphological examination and then incorporates assays that measure membrane disruption, cytoplasmic or intracellular-content leakage, and cellular viability. The resulting observations can be considered together to characterize the extent and nature of damage. This combined workflow supports comparisons among experimental treatments, biological conditions, and tissue-injury states.
It is useful when researchers need to characterize tissue pathology, inflammation, disease mechanisms, or the safety of an experimental treatment. Measurements can show how toxins, infection, ischemia, physical stress, or other treatments influence cell survival and damage. The results also enable comparisons between conditions, helping identify biological responses associated with injury.
