Cell isolation is a laboratory technique used to separate specific cells from a mixed population. This process is essential for studying individual cell types, understanding their functions, and conducting experiments. Techniques such as flow cytometry and magnetic-activated cell sorting are commonly employed to achieve this separation. Once isolated, researchers can analyze the cells for various characteristics, including gene expression and response to treatments. Cell isolation is crucial in fields like immunology, where scientists study immune cells to develop therapies for diseases. It also plays a significant role in stem cell research, enabling advancements in regenerative medicine.
