Overview of cell culture techniques

1.1 Definition and history

Cell culture is a technique that mimics the environment of an organism in vitro to allow cells to survive, grow and multiply. The technique originated in the late 19th century and has become an integral part of the biomedical field after more than a hundred years of development.

1.2 Importance and Applications

Cell culture has a wide range of applications in the fields of drug discovery and development, disease modeling, genetic engineering, and tissue engineering. It provides a platform for scientists to study cell behavior and biological processes under controlled conditions.

1.3 Cell Culture Methods

• Primary Culture : Cells are directly isolated from tissues for cultivation and the biological properties of the original tissues are maintained.
• Passage culture: the primary cells are passaged several times to obtain a sufficient number of cells for experiments.
• Stem cell culture: targeting stem cells with self-renewal and differentiation potential for regenerative medicine and disease treatment research.
