spinal cord regeneration stem cells

doi: 10.1016/j.jneumeth.2016.06.004, Moonen, G., Satkunendrarajah, K., Wilcox, J. T., Badner, A., Mothe, A., Foltz, W., et al. Sekhon, L. H., and Fehlings, M. G. (2001). One of the additional major players implicated in mediating cell death in SCI is autophagy, which under normal conditions plays an important role in the maintenance of homeostasis by recycling toxic agents, unnecessary proteins, and damaged organelles through an autophagosomal and lysosomal process. The discovery of the regenerative capability of central nervous system neurons in the proper environment and the verification of neural stem cells in the spinal cord once incited hope that a cure for SCI was on the horizon. https://t.co/O7fjnCoYuW, This study looks at investigating karyotype and genome size of tick cell lines. Early intravenous delivery of human brain stromal cells modulates systemic inflammation and leads to vasoprotection in traumatic spinal cord injury. doi: 10.1016/j.expneurol.2012.08.004, Yokota, K., Kobayakawa, K., Kubota, K., Miyawaki, A., Okano, H., Ohkawa, Y., et al. Utilizing retrograde neuronal tracing and drug-induced ablation of host neurons, it was demonstrated that the reorganized propriospinal circuits generated through synaptic formation between graft-derived neurons and host-derived neurons directly contributed to functional recovery after NSPC transplantation (Yokota et al., 2015). doi: 10.1097/brs.0000000000002871, Singh, A., Tetreault, L., Kalsi-Ryan, S., Nouri, A., and Fehlings, M.

(2010). doi: 10.1371/journal.pone.0037589, Karus, M., Ulc, A., Ehrlich, M., Czopka, T., Hennen, E., Fischer, J., et al. With the aim of generating translational data, the group then studied the effects of transplanting human spinal cord–derived NSPCs and the growth cocktail-enhanced fibrin matrix into sites of cervical SCI in rhesus monkeys. Worldwide, the estimated incidence of SCI ranges from 250,000–500,000 individuals per year (Singh et al., 2014). The overwhelming cell death and tissue degeneration from the acute to chronic phases after SCI promotes the loss of parenchymal tissue at the lesion epicenter and leads to the formation of cystic cavities referred to as syringomyelia (Seki and Fehlings, 2008). Biomaterials 34, 5107–5116. The axons from the engrafted NSPCs formed synapses that led to improved electrophysiological and functional improvements (Lu et al., 2012). Nature 416, 636–640. J. Neurochem. With the large cavity forming after SCI being an obstacle for regenerating axons, there have been many attempts to implant constructs into the cavity to provide axons with a substrate on which to grow and to restore tissue continuity across the trauma zone. J. Neurotrauma 19, 223–238. (2015). Perivascular fibroblasts form the fibrotic scar after contusive spinal cord injury. Neurons, oligodendrocytes, and other components essential for neuronal transmission are physically insulted (Wilcox et al., 2017), and the disrupted vascular components, including the blood-spinal cord barrier (BSCB), induce infiltration of inflammatory cells (Kunis et al., 2013; Shechter et al., 2013; Li et al., 2017). (2015). J. Neurosci. Furthermore, it is becoming increasingly apparent that propriospinal interneurons that act as bridges between supraspinal neurons and motor neurons play an important role in the plastic reorganization of spinal circuits, contributing an important substrate for recovery from SCI (Courtine et al., 2008). Exp. doi: 10.1016/j.jconrel.2014.05.040, Evans, T. A., Barkauskas, D. S., Myers, J. T., Hare, E. G., You, J. Q., Ransohoff, R. M., et al. Rho inhibitor VX-210 in acute traumatic subaxial cervical spinal cord injury: design of the spinal cord injury rho inhibition investigation (SPRING) clinical trial. Figure 2. The actual process of voluntary limb movement and posture control is complex, involving a coordinated synchronous activation of multiple units that are modulated by sensory feedback loops from muscles, tendons, and skin (Bikoff et al., 2016). J. Neurosurg. Not only that, but it is the first such therapy to look into treating this kind of injury, that has ever received government approval for sale to patients. (2014). Neuron 100, 120–134.e6. 32, 13956–13970. Spinal cord-derived NSPCs suspended in a fibrin matrix containing brain-derived neurotrophic factor, basic fibroblast growth factor, vascular endothelial growth factor, and a calpain inhibitor were loaded into the scaffolds and inserted into a rat thoracic cord transection lesion. doi: 10.1179/2045772314y.0000000224, Liu, Y., Ye, H., Satkunendrarajah, K., Yao, G.

These cells represent potential treatments for SCIs. These tracing methods allow us to visualize the morphology and axonal tract of a specific group of neurons and examine different neurons depending on the amount, sensitivity, and diffusion extent of the tracer. NT3-chitosan enables de novo regeneration and functional recovery in monkeys after spinal cord injury.
