ABSTRACT
Nerve growth factor (NGF)-induced neurite maturation in PC12D cells involves neuritogenesis and neurite outgrowth. Actions of compounds affecting the neurite maturation are sometimes invisible behind the individually variable events in nature even in the clonal population. In this study, we designed a time-lapse imaging system to determine the timing of each event in individual PC12D cells. To examine the system, we analyzed the effect of staurosporine on the neurite maturation in PC12D cells. By using the system, we obtained four event timing data sets (stimulation by NGF with and without staurosporine at the concentrations of 0.01, 0.1, and 1 microM). A permutation test of these data sets revealed that staurosporine caused an early induction of neurite outgrowth during neurite maturation in PC12D cells. These results suggest that the time-lapse imaging system to determine the timing of each event in individual cells can provide a novel insight into features of a cell mass by single-cell analysis and is expected to be utilized for profiling of compounds that can serve as candidate drugs.
