Rat neuronal stem cell line 1464R
Neural stem cell line 1464R is a spontaneously immortalized cell line obtained from brain stem cultures of adult male Fischer 344 rats. It can be cultured for a long period of time and maintained without morphological changes even after repeated passaging. In the presence of retinoic acid, 1464R cells stop dividing and differentiate mainly into tubulin beta-III (TuJ1)-positive neurons. They also differentiate into GFAP-positive astrocytes and O4-positive oligodendrocytes as glial cell lineages. This product was established by Professor Kazuhiko Watabe of the Laboratory of Molecular Neurobiology, Kyorin University School of Health Sciences, and is sold under license from the Tokyo Metropolitan Institute of Medical Science.
Floating culture of neurosphere (undifferentiated)
