advantages of animal cell culture

The tests to ensure this, such as growth curves and time of reaching a confluent monolayer, are similar, to those used to ensure that serum batches are satisfactory. He made detailed ob­servation of mitosis. While cul­tured cells can be used to produce many important products, three areas are gen­erating the most interest. Industrial Fermentation Process (Batch & Continuous Fermentation), Difference between Batch and Continuous Fermentation, Applications of Restriction Endonuclease Enzymes in Biotechnology (Short Notes), Enzyme Immobilization Methods and Applications (Biotechnology Lecture Notes), Industrial Fermentation Process (Batch, Fed-batch and Continuous Fermentation). The control of the physiochemical environment in the culture system is one of the most important advantages of cell culture system. Ø  With the invention of live cell imaging technique and fluorescent tagging methods, many physiological and molecular events in the cells can be visualized in a relatively inexpensive way through the use of in vitro cultured cells. Media that cannot be autoclaved must be ster­ilized through a 0.22 mm pore size membrane filter. Ø  Most of the primary cell in culture will only have limited number of passages. History of Animal Cell Culture 2. The regulation of pH is done using a variety of buffering systems. Cell Culture Cell culture is one of the major tools used in cellular and molecular biology, providing excellent model systems for studying the normal physiology and biochemistry of cells (e.g., metabolic studies, aging), the effects of drugs and toxic compounds on the cells… [pic][pic][pic][pic]A few of the advantages perceived in the use of biotechnology in agriculture are rapid multiplication of plant species, breeding of resistant varieties, diagnosis and control of disease in crop and livestock, utilization of crop residues and animal waste. The CO2 exists in the medium in the form of car­bonic acid and protons. Primary cell culture is increasingly being used as a major tool in cellular and molecular biology, providing excellent model systems for studying the normal physiology and biochemistry of cells (e.g., metabolic studies, aging, signaling studies), the effects of drugs and toxic compounds on the cells and mutagenesis and carcinogenesis. In addition, some normal cells, such as those found in the blood, do not normally attach to sub­strates and always grow in suspension. Kohler and Milstein produced the first hybridoma ca­pable of secreting a monoclonal antibody. d. It is the most expensive component of the culture medium. all type of media composes of many essential components which used by cells for growth proliferation and differentiate during culture… 5. Since both normal cells and cancer cells can be grown in cul­ture, the basic differences between them can be closely studied. The theory and techniques for cryopreserving cells are covered in the Corning Technical Bulletin: General Guide for Cryogenically Storing Animal Cell Cultures. Please Share the PDF with your Friends, Relatives, Students and Colleagues…, @. Where possible, a separate room should be made available for clean cell culture work. In addition to an airflow cabinet and benching which can be easily cleaned, the cell culture laboratory will need to be furnished with an incubator or hot room to maintain the cells at 30-40°C. Advantages of Animal Cell Culture: a. One of the major advantages of cell culture is the ability to manipulate the physico-chemical (i.e., temperature, pH, osmotic pressure, O 2 and CO 2 tension) and the physiological environment (i.e., hormone and nutrient concentrations) in which the cells propagate. Cultured cells are widely used alone or in conjunction with animal tests to study the effects of new drugs, cosmetics and chemicals on survival and growth in a wide variety of cell types. A variety of tissue culture plastic-ware is avail­able, the most common being specially treated polystyrene. Like: cells that are attached to a substrate and appear flattened and polygonal in shape. ANIMAL CELL CULTURE MEDIA COMPOSITION. The optimum pH is essential to maintain the proper ion balance, optimal functioning of cellular enzymes and bind­ing of hormones and growth factors to cell surface receptors in the cell cultures. It is important to maintain conti­nuity in cells to prevent genetic drift and to guard against loss of the cell line through con­tamination and other disasters. primary tissue culture?Several different types of culture are routinely performed. Ø  Cell culture techniques allow us to maintain the homogeneity of cells by the use of selective media. Characteristics 5. Salt, Glu­cose and Amino acids in the growth media determine the osmolality of the medium. Carrel introduced strict aseptic techniques so that cells could be cultured for long periods. This will insulate the am­poules to slow the freezing process to 1°C/min in a -70°C freezer. 2. The term “Tissue Culture” was for the first time coined by Thomas Burrows. Insect cells are widely used as miniature cells factories to express substantial quan­tities of proteins that they manufacture after being infected with genetically engi­neered baculoviruses.
