Electromagnetic field and other physical methods influencing cell growth in mammal cell culture systems

The growth rate of cultured mammalian cells can be influenced by chemical and physical methods such as electromagnetic fields (EMF), light, temperature and plasma. These physical methods have a number of well documented effects on mammalian cells including modification of gene expression, cell cycle, invasion, motility, cell viability, proliferation, apoptosis and mammosphere numbers. A study of the existing literature confirms that the impact of physical method on mammalian cells depends on the cell type, culture environment, exposure time, frequency, wave shape, and amount of dose. The modification of cell proliferation and apoptosis is necessary for cells products, tissue engineering, and therapy. In this article, we reviewed the impact of four physical methods on the growth rate and viability of cells. Plasma is the best method among fours because we can get desired result ranging from increasing cell proliferation to inducing apoptosis depending on the dose.
