Cell culture medium is a crucial basic substance in cell culture and has a wide range of specific applications in multiple fields. The following are some of the main aspects:

Cell Therapy: In cell therapy technologies such as CAR-T cell therapy and stem cell therapy, cell culture medium is used to culture and expand the cells required for treatment. For example, in the preparation process of CAR-T cells, T cells are cultured in a specific medium to enable their massive proliferation and gene editing, so as to obtain CAR-T cells with the ability to precisely kill tumor cells.
Vaccine Production: The production of many vaccines relies on cell culture technology, and cell culture medium provides support for the growth of cells in vaccine production. For instance, in the production of influenza vaccines, chicken embryo fibroblasts, etc. are cultured in the medium, providing an environment for the proliferation of influenza viruses, and then the viruses are harvested for vaccine preparation.
Drug Research and Development: In drug screening and drug toxicology research, cell culture medium is the basis for culturing various cell lines. Researchers can place different cells in the medium, add the drugs to be screened, and observe the changes in cell growth, metabolism, etc., so as to screen out drugs with potential therapeutic effects. At the same time, by observing the toxic reactions of drugs on cells, the safety of drugs can be evaluated.

Cell Biology Research: Cell culture medium is a necessary condition for studying basic life activities such as cell growth, proliferation, differentiation, and apoptosis. For example, when studying the differentiation of nerve cells, neural stem cells are placed in a specific medium, and different growth factors and other components are added to observe the process and mechanism of neural stem cells differentiating into neurons or glial cells.
Molecular Biology Research: It is used to culture cells to obtain a sufficient number of cell samples for molecular biology experiments such as gene cloning, gene expression analysis, and protein synthesis and function research. For example, in gene expression research, cells are cultured in the medium, and RNA and proteins in the cells are extracted to analyze the expression levels and regulatory mechanisms of specific genes under different conditions.
Developmental Biology Research: In the culture of embryonic stem cells and the research of embryonic development, cell culture medium simulates the in vivo environment to support the growth and differentiation of embryonic stem cells and the in vitro culture of early embryos. For example, mouse embryonic stem cells are cultured in a specific medium to study their differentiation potential into cells of different germ layers and the regulatory mechanisms, providing important information for understanding the process of embryonic development.

Biopharmaceuticals: Animal cells are cultured on a large scale to produce biological products such as monoclonal antibodies, cytokines, and growth hormones, and cell culture medium is a key factor to ensure large-scale cell production. By optimizing the medium formula and culture conditions, the cell growth density and product expression level can be increased, and the production cost can be reduced.
Cosmetics R&D: In the evaluation of the efficacy and safety testing of cosmetics, skin cells, keratinocytes, etc. are cultured using cell culture medium. By observing the effects of cosmetic ingredients on cells, the efficacy of cosmetics such as whitening, moisturizing, and antioxidant properties, as well as potential irritation and toxicity, can be evaluated.

Plant Cell Culture: It is used for the culture of plant cells to produce secondary metabolites, such as active ingredients like alkaloids and flavonoids in medicinal plants. By culturing plant cells in the medium and optimizing the culture conditions, the large-scale production of these secondary metabolites can be achieved, providing raw materials for the production of natural drugs and health products.
Animal Cell Culture: It has important applications in the production of animal vaccines, growth factors, etc. through animal cell culture. For example, animal cells are cultured to produce vaccines such as classical swine fever vaccine and foot-and-mouth disease vaccine, providing a guarantee for the prevention and control of animal diseases.
