Project description:Expression analysis was performed with in vitro cultured cerebellar granule neurons (CGNs) isolated from rat brain. The CGNs were culture for four weeks. Each sample was collected after interval of seven days. No treatment was given to any cultured neurons at any time point. The purpose of the experiment was to identify the genes differentially expressed during the senescence of CGNs. The experiment is useful in revealing the senescence associated genetic markers in neurons.
