Abstract
Cell lines are an important tool for scientific research and clinical and pharmaceutical applications. Cells are isolated from animal tissues and can be expanded in culture to study cell biology and disease. The isolated cells can be used to produce antibodies, proteins, and vaccines. Immortalized cell lines can grow in vitro and are commonly used as models for complex biology. The most frequently used type of cell culture for scientific research and clinical and pharmaceutical applications is the two-dimensional (2D) model, but recently, the popularity of the three-dimensional (3D) cultivation method is growing.
