3D 细胞培养是将细胞以三维结构培养，模拟更接近体内环境的技术。与传统的 2D 培养相比，3D 培养提供更真实的细胞相互作用、组织结构和细胞功能。这种培养方法广泛用于生物医学研究、药物筛选和组织工程。通过创建更接近生物体内环境的三维结构，3D 细胞培养有助于更准确地模拟疾病发展、药物反应和组织重建等生物学过程。

3D cell culture is a technology that cultivates cells in a three-dimensional structure to simulate the environment closer to the body. Compared with traditional 2D culture, 3D culture provides more realistic cell interactions, tissue structure and cell function. This culture method is widely used in biomedical research, drug screening, and tissue engineering. By creating three-dimensional structures that more closely resemble the environment within an organism, 3D cell culture helps more accurately simulate biological processes such as disease development, drug response, and tissue reconstruction.
