细胞分选是通过技术手段将混合细胞群中的特定类型细胞分离出来的过程。常用的细胞分选方法包括流式细胞术（FACS）、磁珠分选、细胞沉降和微流控技术等。这些方法广泛应用于细胞生物学、免疫学、干细胞研究和癌症细胞分析等领域，为纯化特定细胞亚群、研究细胞功能、筛选药物等提供了重要手段。

Cell sorting is the process of using technology to separate specific types of cells from a mixed cell population. Commonly used cell sorting methods include flow cytometry (FACS), magnetic bead sorting, cell sedimentation, and microfluidic technology. These methods are widely used in fields such as cell biology, immunology, stem cell research, and cancer cell analysis, providing important means for purifying specific cell subpopulations, studying cell functions, and screening drugs.
