Cell sorting is a method used in research and clinical settings to separate cells based on specific characteristics such as size, shape, and surface markers. This process allows researchers to isolate and study individual cell populations, which is important for understanding cellular function, disease progression, and developing targeted therapies. Cell sorting techniques include flow cytometry, magnetic-activated cell sorting, and fluorescence-activated cell sorting, among others. These methods are used in a variety of fields such as immunology, stem cell research, and oncology.
