Rat glioma cell line as a model for astrogliosis.
In this investigation 9L rat glioma cells were grown on coverslips in culture, and when subjected to mechanical trauma, they were capable of mounting an astroglial response, without interaction with neurons, as evidenced by cell hypertrophy and increased immunostaining for glial fibrillary acidic protein and J1-31 antigen. It is of particular interest that this neoplastically transformed cell line is capable of mounting an astroglial response when subjected to mechanical trauma in vitro. The advantages of this model over in vivo models of central nervous system injury include the ease of reproducibility of results, and the ability to investigate molecular mechanisms under controlled conditions.
