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,...

Achieving high quality and appropriate quantity of human islets is one of the prominent prerequisites for successful islet transplantation. In this video, we describe step by step the procedures for human pancreatic islet isolation (part I: digestion and collection of pancreatic tissue) using a modified automated method.
FAQs
Premature activation of pancreatic digestive enzymes initiates autodigestion, in which the gland and nearby fat are damaged by enzymes meant for digestion. This injury amplifies inflammation, compromises local blood flow, and promotes tissue breakdown. The linked processes explain why necrosis can extend beyond the pancreas and why clinical severity requires close assessment.
Sterile and infected necrotic collections represent different clinical situations. A collection may remain free of infection, or bacteria may reach it through bacterial translocation. That distinction is important because antibiotics are considered when infection is suspected or confirmed, whereas persistent symptoms or systemic complications may prompt drainage or minimally invasive necrosectomy.
Contrast-enhanced computed tomography helps identify whether necrosis is present and maps its extent. This anatomical information complements clinical assessment rather than replacing it: imaging shows the distribution of damaged tissue and collections, while the patient's clinical status helps determine risk and the need for monitoring or intervention.
Initial management may center on supportive critical care and nutritional support while the patient is monitored. These measures address immediate clinical needs associated with severe acute pancreatitis, while clinicians assess whether collections remain sterile, become infected, or produce persistent symptoms and systemic complications that change the treatment plan.
Antibiotics have a targeted role linked to infection status. They may be used when infection is suspected or confirmed, particularly because bacterial translocation can infect previously sterile material. Clinical assessment and the evolving status of the collection therefore help determine whether antibiotic treatment is appropriate, alongside other management decisions.
Drainage or minimally invasive necrosectomy is generally delayed until collections cause persistent symptoms or systemic complications. This approach allows treatment to be matched to the collection's clinical impact instead of intervening solely because necrotic tissue is visible. The choice follows monitoring, imaging-defined extent, and assessment of infection and complications.
