体细胞培养是将多种动植物组织中的细胞以体外方式培养和繁殖的技术。该方法常用于细胞学、生物医学研究和生物工程等领域。细胞在培养基中得到适当营养和生长条件，使其在无体内环境下维持生长、分化和功能。体细胞培养广泛应用于药物筛选、基因工程、细胞治疗和生物生产等方面，为疾病研究和药物开发提供了重要工具。

Somatic cell culture is a technique for cultivating and propagating cells from various animal and plant tissues in vitro. This method is commonly used in fields such as cytology, biomedical research, and bioengineering. Cells are provided with appropriate nutrients and growth conditions in culture media, allowing them to maintain growth, differentiation, and function in the absence of an in vivo environment. Somatic cell culture is widely used in drug screening, genetic engineering, cell therapy and biological production, providing an important tool for disease research and drug development.
