Developing in vitro cell culture models that accurately mimic in vivo processes in a manner that also enables near real-time analysis of neurotransmitters is an important research area. New technologies being developed such as 3D scaffolds for cell culture and 3D printed microfluidics provide an opportunity.
Cell culture is the process by which cells are grown under controlled conditions, generally outside their natural environment. After the cells of interest have been isolated from living tissue, they can subsequently be maintained under carefully controlled conditions.These conditions vary for each cell type, but generally consist of a suitable vessel with a substrate or medium that supplies.
Other methods such as gentle cell scraping or using a very mild dissociation reagent (Versene) can often be used as a substitute in these circumstances. When all cells are detached, neutralise the dissociation reagent with serum containing growth medium appropriate to the cell line in culture. Transfer cell suspension to a centrifuge tube.
Raman spectroscopy provides chemical-rich information about the composition of analytes and is a powerful tool for biological studies. With the ability to investigate specific cellular components or image whole cells, compatible methods of sample preservation must be implemented for accurate spectra to be collected. Unfortunately, the effects of many commonly used sample preservation methods.
Immortalized Cell Lines. Continuous immortalized cell lines are comprised of a single cell type that can be serially propagated in culture either for a limited number of cell divisions (approximately thirty) or otherwise indefinitely. Cell lines of a finite life are usually diploid and maintain some degree of differentiation. The fact that such cell lines senesce after approximately thirty.
Tissue Culture Methods. I. TYPES OF CELLS GROWN IN CULTURE. Tissue culture is often a generic term that refers to both organ culture and cell culture and the terms are often used interchangeably. Cell cultures are derived from either primary tissue explants or cell suspensions.
