Molecular characterization of our analogs for scar ablation is complete. The Spinal Cord Society developed a number of molecules and identified one in particular which demonstrated its intended purpose: Octyl-amine. In our preliminary studies, this derivative appears to properly attenuate so that perfusion into the tissue is slowed down and the ablative effects are reduced. This modification to our existing scar ablation procedure will allow a more targeted approach while avoiding damage to the surrounding spared tissue. We have made sufficient quantities of this compound and are currently using them in an animal trial with OPC's.
As we enter 2017, we are near completion of the initial training and testing of our new scar ablation analogs. The next step will be to provide more of the analogs (further synthesis of the same analogs in quanity for the cell trials) for human cell inclusion and a detailed molecular characterization of these analogs. This project is under the directive of Dr. Holmberg's laboratory in Alaska. It's projected timeline is February 1 – July 2017. The scar ablation testing of these analogs is ongoing at the University of Minnesota.
November 13, 2016, Dr. Ann Parr, Assistant Professor at the Department of Neurosurgery's Stem Cell Institute at the University of Minnesota, gave a video presentation detailing her work and her collaborative efforts with the Spinal Cord Society.
During March 2016, we began our latest animal experiment. This experiment will involve scar ablation training and testing of our new scar ablation analogs. The goal is to improve scar disruption using rose-Bengal.
A $125,000 grant was awarded to Dr. Ann Parr of the University of Minnesota Stem Cell Institute. This grant is part of the Omnibus Higher Education Bill. Spinal Cord Society funds will be leveraged with this grant for the purpose of a collaboration effort involving a combination therapy with rose-Bengal and human induced pluripotent stem cells (hIPSC) derived oligodendrocyte precursor cells (OPC's).
During November 2015, the Spinal Cord Society welcomes Dr. Nandadevi Patil, our new research associate. We are very excited to have her join our collective projects.
The Spinal Cord Society laboratory in Ft. Collins, Colorado was formally closed on March 2, 2015.
By invitation, we submitted a manuscript entitled “Scar Removal,Cell Transplantation, and Locomotor Training-Strategies to Improve Tissue Repair and Functional Recovery in Rat with Chronic Spinal Cord Injury". It has been accepted for publication in a forthcoming Special Issue on “Spinal Cord Injury: Treatment & Rehabilitation” in the International Journal of Physical Medicine & Rehabilitation. This manuscript is written mainly based on our own study of chronic spinal cord injury during the recent 10 years.
The process of moving the Spinal Cord Society Research Center from the campus of Colorado State University to the University of ,Minnesota has begun. The initial plan for our participation in the new projects include establishing human protocals for scar ablation, combining it with human IPC's (induced pluripatent stem cells) to determine the maximum suitability for treatment, testing the combinations with the human cells and preparing for human trial.
On August 4, 2014, the staff at Spinal Cord Society (SCS) National along with Dr. Eric Holmberg, SCS Research Director and Dr. Zhang, SCS Research Scientist, met at the University of Minnesota. Our discussion centered around our common goal of bringing the development of research to treatment of human spinal cord injury.
During April 2013, as part of our collaborative effort with the University of Minnesota, the Spinal Cord Society Research center commenced an animal experiment involving the transplantation of oligodendrocyte precursor cells (OPCs) along with the lamina propria of olfactory mucosa into our chronic rat model. Additionally, tail nerve electrical stimulation (TANES) will follow to promote functional recovery. This study is projected to end in May 2014.
In December 2012, the Spinal Cord Society Research Center began a collaborative effort with Dr. Ann Parr, Assistant Professor, at the Department of Neurosurgery's Stem Cell Institute at the University of Minnesota.
In October 2012, Dr. Shu-xin Zhang, Spinal Cord Society Research Scientist, was invited to visit Sun Yat-sen University School of Medicine in Guangzhou, China and give a talk about our research results in glial scar ablation and tail nerve electrical stimulation for functional recovery after spinal cord injury. A collaboration between Dr. Zhang and Dr. Yuang-Shan Zeng, professor and head of Department of Histology and Embryology and co-director of Spinal Cord Injury Institute of Sun Yat-sen University School of Medicine, is underway.
The National Neurotrauma Symposium was held in Phoenix, Arizona on July 22 - 25, 2012. Approximately 500 scientists attended this meeting and 390 posters were presented. There were 32 posters related to spinal cord injury while others were studies on traumatic brain injury or peripheral nerve injury.
Among 32 posters of spinal cord injury, there were 4 from clinical studies. The Spinal Cord Society poster was alone in exhibiting the chronic injury model. Furthermore, ours was the only poster related to cell transplantation therapies.
Dr. Zhang presented our poster relating to our recent combination treatment results with motor function caused by the TANES, as evidenced in the video at the bottom of this page.
