Utilization Of Structural And Biochemical Cues To Enhance Peripheral Nerve Regeneration, Balendu Shekhar Jha
Utilization Of Structural And Biochemical Cues To Enhance Peripheral Nerve Regeneration, Balendu Shekhar Jha
Theses and Dissertations
This study examines the prospects of using the electrospinning process to fabricate tissue engineering scaffolds targeting a variety of regenerative applications, with a primary focus on the production of nerve guides for the treatment of long-defect nerve injuries in the peripheral nervous system. A basic overview of the conventional electrospinning process is provided, and the utility of this fabrication scheme in the production of collagen-based tissue engineering scaffolds is demonstrated. Next, a novel modification of the basic electrospinning process is presented. This process, called two pole air gap electrospinning, was developed to produce nerve guides that exhibit an anisotropic structure …
Sulfatide Is Required For Organization Of The Paranode In The Myelinated Axon In The Peripheral Nervous System, Eva Kwong
Theses and Dissertations
Myelin facilitates the timely, efficient conduction of action potentials along axons. Made by Schwann cells (SCs) in the PNS, myelin is unique in that it is composed of a high percentage of lipids, particularly galactolipids. Sulfatide, one such galactolipid, is made by cerebroside sulfotransferase (CST) and has been shown to play a role in organizing paranodal domains in myelinated axons. However less is known regarding the involvement of sulfatide in the establishment and maintenance of the node, of particular interest as it is responsible for the potentiation of action potentials along the axon. Using immunohistochemical and, to a lesser extent, …
