abstract = {Olfactory nerve derived and olfactory bulb derived olfactory ensheathing cells (OECs) have the ability to promote axonal regeneration and remyelination, both of which are essential in a successful cell transplant. Thus, morphological identification of OECs is a key aspect to develop an applicable cell therapy for injuries to the nervous system. However, there is no clear definition regarding which developmental stage or anatomical origin of OECs is more adequate for neural repair. In the present study, an ultrastructural comparison was made between OECs recovered from primary cultures of olfactory nerve and bulb in two developmental stages. The most notorious difference between cells obtained from olfactory nerve and bulb was the presence of indented nuclei in bulb derived OECs, suggesting a greater ability for possible chemotaxis. In neonatal OECs abundant mitochondria, lipid vacuoles, and smooth endoplasmic reticulum were detected, suggesting an active lipid metabolism, probably involved in synthesis of myelin. Our results suggest that neonatal OECs obtained from olfactory bulb have microscopic properties that could make them more suitable for neural repair.},
