Immortalization of a cell line with neural stem cell characteristics derived from mouse embryo brain

BACKGROUND: Neural stem cells (NSC) have been extensively used as a tool to investigate the mechanisms responsible for neural repair, and they have been also considered as the source for a series of promising replacement therapies in various neurodegenerative diseases. However, their use is limited by their relative rarity and anatomical localization, and also because, the methods for isolation and characterization are usually time consuming and have some technical limitations. RESULTS: In this study, we describe a resource and method for obtaining immortalized cells with NSC characteristics obtained from mouse brain embryo. CONCLUSIONS: Because these cells can be maintained indefinitely in culture, they may constitute a permanent source of NSC that can be used for research studies on neural development and regeneration.
