Cell isolation is a research area that involves the separation and extraction of specific cells from a heterogeneous population. This process is crucial in various scientific fields, such as cell biology, immunology, and regenerative medicine, as it allows researchers to study and analyze individual cell types in isolation. Cell isolation methods can vary depending on the type of cells being targeted and the desired outcome, but commonly used techniques include fluorescence-activated cell sorting (FACS), magnetic-activated cell sorting (MACS), and density gradient centrifugation. Cell isolation is essential for advancing our understanding of cellular behavior and function, as well as for developing new therapies and treatments for various diseases.
