[0002] Cell culture refers to a method of simulating the in vivo environment (sterility, suitable temperature, pH and certain nutritional conditions, etc.) in vitro to enable it to survive, grow, reproduce and maintain its main structure and function. Cell culture is also called cell cloning technology, and the formal term in biology is cell culture technology. Whether it is for the entire bioengineering technology or one of the biological cloning technologies, cell culture is an indispensable process, and cell culture itself is the large-scale cloning of cells. Cell culture technology can transform a cell into a simple single cell or a multi-cell with very little differentiation through large-scale culture. This is an indispensable part of cloning technology, and cell culture itself is the clone of cells. Cell culture technology is an important and commonly used technology in cell biology research methods.
