Glial cell line-derived neurotrophic factor (GDNF) and its receptor GFRα1 are prominently expressed in the olfactory epithelium (OE) and olfactory bulb (OB), but their importance for olfactory system development is completely unknown. We have investigated the consequences of GFRα1 deficiency for mouse olfactory system development and function. In the OE, GFRα1 was expressed in basal precursors,...
Myelin-forming glial cells transplanted into the demyelinated spinal cord can form compact myelin and improve conduction properties. However, little is known of the expression and organization of voltage-gated ion channels in the remyelinated central axons or whether the exogenous cells provide appropriate signaling for the maturation of nodes of Ranvier. Here, we transplanted olfactory ensheat...
Transcription factor SOX10 plays a role in the maintenance of progenitor cell multipotency, lineage specification, and cell differentiation and is a major actor in the development of the neural crest. It has been implicated in Waardenburg syndrome (WS), a rare disorder characterized by the association between pigmentation abnormalities and deafness, but SOX10 mutations cause a variable phenotyp...
During development of the primary olfactory system, axon targeting is inaccurate and axons inappropriately project within the target layer or overproject into the deeper layers of the olfactory bulb. As a consequence there is considerable apoptosis of primary olfactory neurons during embryonic and postnatal development and axons of the degraded neurons need to be removed. Olfactory ensheathing ...
(2015) Harvesting of olfactory ensheathing cells for autologous transplantation into the spinal cord injury. Its complexity in dogs. The mucosa lining the nasal cavity and its content contains olfactory sensory neurons (OSNs). The OSNs are organized into different territories (four in mammals with a more sophisticated model) and, with the exception of the OSNs enclosed in the vomeronasal organ,...
The molecular mechanisms used by olfactory ensheathing cells (OECs) to promote repair in the damaged adult mammalian CNS remain unknown. Thus, we used microarrays to analyze three OEC populations with different capacities to promote axonal regeneration in cultured rat retinal neurons. Gene expression in "long-term cultured OECs" that do not stimulate adult axonal outgrowth was compared with tha...
Olfactory ensheathing cells (OEC) are a promising graftable cell population for improving functional outcomes after experimental spinal cord injury. However only few studies have focused on experimental models with large cavitations, which require bridging substrates to transfer and maintain the donor cells within the lesion site. Here, a state-of-the-art collagen-based multi-channeled three di...
Sciatic nerve remyelination and nodal formation following olfactory ensheathing cell transplantation
SCIATIC NERVE REMYELINATION AND NODAL FORMATION FOLLOWING OLFACTORY ENSHEATHING CELL TRANSPLANTATION. Mary A. Dombrowski, Masanori Sasaki, Karen L. Lankford, Hajime Tokuno, Christine Radtke, Jeffery D. Kocsis. Department of Neurology and Center for Neuroscience and Regeneration Research, Yale University School of Medicine, New Haven, CT, Rehabilitation Research Center, Veterans Affairs Connecti...
