| الوصف: | Background Studying human ageing is of increasing importance due to the worldwide ageing population. However, it faces the challenge of lengthy experiments to produce an ageing phenotype. Often, to recreate the hallmarks of ageing requires complex empirical conditions that can confound data interpretation. Indeed, many studies use whole organisms with relatively short life spans, which may have little, or limited, relevance to human ageing. There has been extensive use of cell lines to study ageing in human somatic cells, but the modelling of human neuronal ageing is somewhat more complex in vitro. New Method We cultured the well-characterised SH-SY5Y human neural cell line to produce high purity cultures of cells differentiated to express a neuronal phenotype, and designed a protocol to maintain these cells in culture until they accumulated biomarkers of cellular ageing. Results Our data validate a novel and simple technique for the efficient differentiation and long-term maintenance of SH-SY5Y cells, expressing markers of neuronal differentiation and demonstrating electrical activity in culture. Over time in vitro, these cells progressively accumulate markers of ageing such as enhanced production of reactive oxygen species and accumulation of oxidative damage. Comparison to Existing Methods In comparison to existing techniques to model neuronal ageing our method is cost effective, requiring no specialist equipment or growth factors. Conclusions We demonstrate that SH-SY5Y cells, grown under these culture conditions, represent a simple model of neuronal ageing that is amenable to cell biological, biochemical and electrophysiological investigation. Highlights • Ageing study is often hindered by the need for complex and lengthy experiments. • SH-SY5Y cells underwent neuronal differentiation and were cultured until they were of an aged phenotype. • These cells were electrically active and acquired oxidative damage. • This is a novel technique to model neuronal ageing in vitro. |
