Abstract

Current treatment options for spinal cord injury (SCI) are scarce. One of the most promising innovative approaches include gene-therapy, however no single gene has so far been shown to be of clinical relevance. This study investigates the efficacy of various combinations of vascular endothelial growth factor (VEGF), glial cell-derived neurotrophic factor (GDNF), angiogenin (ANG) and neuronal cell adhesion molecule (NCAM) in rats. Multiple therapeutic genes were administered intrathecally either via adenoviral vectors or by using genetically modified human umbilical cord blood mononuclear cells (hUCBMCs). Following the induction of SCI, serial assessment of cord regeneration was performed, including morphometric analysis of gray and white matters, electrophysiology and behavioral test. The therapeutic gene combinations VEGF+GDNF+NCAM and VEGF+ANG+NCAM had positive outcomes on spinal cord regeneration, with enhanced recovery seen by the cell-based approach when compared to direct gene therapy. The efficacy of the genes and the delivery methods are discussed in this paper, recommending their potential use in SCI.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
