| Research Abstract |
Including neural stem cells, olfactory ensheathing cells olfactory ensheathing cell and (OEC), and in the spinal cord injury treatment, olfactory mucosa is one of the leading cell source. There is variation in the reports of neurite outgrowth-promoting effect of OEC isolated from the olfactory mucosa in many studies. To the cause, not only OEC isolated, there is interaction with other cells that are included in the olfactory mucosa. As a result of separating the olfactory epithelium olfactory epithelium that make up the olfactory mucosa (OE), olfactory mucosa lamina propria lamina propria the (LP), we examined the difference in the interaction with the axon, PSA-which is expressed in the OEC of LP in that NCAM is involved in direct interaction with the axon has been shown.
