Cell Culture - Basics, Techniques and Medi

Battery or cells are referred to as the parallel combination of electrochemical cells. The major difference between a primary cell and the secondary cell is that primary cells are the ones that cannot be charged but secondary cells are the ones that are rechargeable Cell Culture Troubleshooting. Cell culture has become one of the most fundamental techniques for modeling biological systems, and is of increasing importance in the biotechnology and pharmaceutical sectors as well as an essential process in life science research labs. Though this technique is highly accessible, successful propagation of cells. Cell cultures can also be adherent or non-adherent in their culturing conditions. Adherent cell types like fibroblasts or epithelial cells are grown by attaching to the culture dish surface. These types of cells need to be physically detached from their surface in order to passage them. Non-adherent cell types, such as lymphoid cells, are grown in suspension in a cell culture flask - they. The cell culture may be divided into three according to their history: 1) primary, 2) secondary and 3) continuous cell culture. The primary and secondary cells are usually diploid cells. Primary cell lines derived directly from an intact tissue like animal's embryo or kidney. Secondary cells are derived from primary cultures Cell culture refers to the removal of cells from an animal or plant and their subsequent growth in a favorable artificial environment. The cells may be removed from the tissue directly and disaggregated by enzymatic or mechanical means before cultivation, or they may be derived from a cell line or cell strain that has already been established

Recent extraction technology such as accelerated solvent extraction or microwave assisted extraction in combination with hyphenated techniques such as gas chromathography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) represent a modern approach to perform fast and reproducible analytical methods for the quality control of secondary metabolite production in 'in vitro' plant material The continuous culture is an open cultivation process, in which the cell growth is maintained in the continuous mode of operations. It works as an open cultivation system, in which the fresh nutrient medium is continuously added into the culture vessel rather than recycling and reuse of the nutrients or substrate.. There is an inlet pump in a continuous cultivation system that continuously.

Then, in secondary cultures that are obtained by passaging, adding to the growth factors that are peculiar to wanted cell type, it can be ensured that a certain cell type proliferate and others are pressed (Ng and Schantz, 2010; Fauza and Bani, 2016) Ø High possibility of cross contamination of different types of cells in culture. Ø Experience and expertise are required for an effective maintenance most of the cells. Ø The capital investment to set-up a cell culture facility is very high. Ø Require through standardization of medium, concentration of nutrients and serum When this cell-to-cell-contact occurs, mitosis is triggered to stop. This is called contact inhibition and it prevents the density of the cells from becoming too high. To prevent contact inhibition, cells from the primary cell culture must be transferred to another vessel with fresh growth medium. This is called a secondary cell culture
