In the field of life science research, cell culture technology supports the development of countless scientific research projects. And cell culture medium, as the core element of cell culture, is like the "nutrient solution" of cells, providing conditions for cell growth, reproduction, and maintenance of normal physiological functions. For beginners who have just entered this field, understanding the relevant knowledge of cell culture media is the key to opening the door to cell culture experiments.

Key components and functions of cell culture medium:

1. Carbohydrates: Carbohydrates play a crucial role in cell culture media and are the main source of energy for cells. Among them, glucose is more commonly used, and cells can convert glucose into the energy required for cellular life activities through two key metabolic pathways: glycolysis and aerobic oxidation. The concentration of glucose in the culture medium usually fluctuates between 1-4.5g/L, and the specific value depends on the cell type and the actual needs of the experiment. Cells with high metabolism and rapid proliferation have a greater demand for glucose, which may require higher concentrations of glucose to meet their energy consumption; On the contrary, some cells that grow slowly can grow normally in environments with lower concentrations of glucose.

2. Amino acids: Amino acids are the basic raw materials for cell protein synthesis, and the culture medium generally contains 20 standard amino acids. Among these amino acids, some types such as lysine and tryptophan cannot be synthesized by cells themselves and need to be taken up from the external environment, hence they are called essential amino acids. Glutamine plays an important role in cellular energy metabolism, especially for rapidly proliferating cells that consume glutamine at an extremely fast rate. Once glutamine is lacking in the culture medium, the growth and metabolism of cells will be severely affected, and may even rapidly lead to death. Therefore, when configuring cell culture media, it is necessary to ensure that the type and content of amino acids meet the growth needs of cells.

3. Vitamins: Vitamins play a crucial role in cellular metabolic activities, acting as catalysts in chemical reactions. Although used in small quantities, they are indispensable. Vitamin C helps cells resist the invasion of free radicals and maintain the stability of the intracellular environment; The vitamin B family, as coenzymes, is widely involved in various enzymatic reactions and plays a crucial role in promoting substance metabolism and energy conversion processes within cells.

4. Inorganic salts: Inorganic salts are an important component in maintaining cell osmotic pressure and electrolyte balance. Inorganic salts such as sodium chloride, potassium chloride, and phosphate work together to create a stable ion concentration environment in the culture medium, ensuring a balance between the intracellular and extracellular environments. This balance plays an important role in maintaining cell morphology, transporting substances, and performing normal physiological functions. If the osmotic pressure of extracellular fluid changes, cells may experience dehydration, wrinkling, or swelling upon water absorption, thereby affecting their normal function.

5. Buffer system: Cells are highly sensitive to pH values and typically require a narrow range of 7.2-7.4 for normal growth. In order to maintain such a stable pH environment, a specialized buffer system is equipped in the culture medium, among which bicarbonate buffer system is more common. When cells metabolize and produce acidic substances, bicarbonate can react with them, consuming hydrogen ions and preventing excessive pH drop; On the contrary, when alkaline substances appear in the environment, the buffer system can release hydrogen ions to neutralize the alkalinity and prevent the pH value from being too high. Once the pH value exceeds the appropriate range, the metabolism and growth of cells will be significantly inhibited, and even cell death may occur.
