DARPA has awarded a $36 million contract to a consortium led by 新澳门六合彩内幕信息 Davis to develop new treatments for spinal cord injuries. The technology will enable better monitoring of patients’ progress and optimize neural stem cell treatments.

Quick Summary

  • $36 million DARPA contract will fund consortium to develop new interventions for spinal cord injury
  • With better diagnostics, researchers hope to find best time to transplant neural stem cells
  • Researchers hope to move to human patients within five years

Engineers at the University of California, Davis, will lead a consortium of universities, biomedical startups and nonprofit organizations to develop interventions for spinal cord injuries that can be applied within days of injury to improve long-term outcomes.

Karen Moxon, professor of biomedical engineering at 新澳门六合彩内幕信息 Davis, will lead the five-year, $36 million contract as part of the Defense Advanced Research Project Agency, or DARPA, . A primary goal is to develop technologies to stabilize a patient鈥檚 hemodynamic response, which includes blood flow and blood pressure, within days of injury.

Because large swings in blood pressure are common following spinal cord injuries, stabilizing hemodynamics within days of injury will improve functional recovery. The team will take advantage of stabilized hemodynamics to optimize delivery of neural stem cells using personalized 3D printed scaffolds within two weeks of injury to regenerate lost connections within the injured spinal cord.

鈥淪pinal cord injury is a complex condition that causes partial or complete loss of function below the location of injury,鈥  Moxon said. 鈥淲e will develop systems for real-time biomarker monitoring and intervention to stabilize and rebuild neural communications pathways between the brain and spinal cord. As a result of our efforts, clinicians will be able to collect previously unavailable diagnostic information for automated or clinician-directed interventions. Our goal is to translate these technologies to humans within the five-year award period.鈥 

Professor Karen Moxon

Professor Karen Moxon will lead a new consortium on spinal injury. 

The international team includes 12 institutions: 新澳门六合彩内幕信息 Davis, 新澳门六合彩内幕信息 San Diego, 新澳门六合彩内幕信息 San Francisco, the University of British Columbia, the University of Calgary and the 脡cole Polytechnique F茅d茅rale de Lausanne (EPFL, Switzerland); biotech startups Pathonix Innovation Inc. of Vancouver, GTX Medical (Lausanne, Switzerland), and Teliatry (Richardson, Texas); nonprofit institutions the Wyss Center for Bio and Neuroengineering (Geneva, Switzerland) and Battelle Memorial Institute (Columbus, Ohio); and a regulatory consultant firm, NetValue BioConsulting Inc., Toronto.

Moxon and her team at 新澳门六合彩内幕信息 Davis 鈥 including  Zhaodan Kong, associate professor in the Department of Mechanical and Aerospace Engineering, and Professor Kiarash Shahlaie and Assistant Professor Julius Ebinu, neurosurgeons in the 新澳门六合彩内幕信息 Davis School of Medicine 鈥 will take the lead on assessing the impact of these interventions on the brain to maximize the restoration of both motor and sensory functions. This part of the project will be conducted at the California National Primate Research Center.

鈥淲e are extremely pleased that the California National Primate Research Center will host the nonhuman primate research arm of this extraordinary effort to restore function following spinal cord injury,鈥 said center director John Morrison, professor of neurology at 新澳门六合彩内幕信息 Davis.

Part of the effort will also aim to improve functional recovery, using neural stem cell and bioengineering scaffold technology developed by professors Mark Tuszynski, Paul Lu, Ephron Rosenzweig and Jacob Koffler, all faculty in the Department of Neurosciences at 新澳门六合彩内幕信息SD. Their stem cell and scaffold technology will be combined with neural electrical stimulation technology (鈥渘euromodulation鈥) developed by Gregoire Courtine at EPFL. The team hopes to successfully combine this cell and engineering technology to promote nerve regeneration that bridges the injury site.

Advancing key technologies

Moxon鈥檚 lab at 新澳门六合彩内幕信息 Davis, in collaboration with a team at the Wyss Center for Bio and Neuroengineering led by Tracy Laabs, will develop cortical stimulation protocols to enhance sensory feedback to the brain and aid in motor control. The team will take advantage of Wyss鈥檚  system that wirelessly records signals from individual neurons in the brain and will further develop it to include closed-loop cortical stimulation, which employs a sensor to record signals, for improved motor function.

The multi-institution team will focus on advancing three main technologies:

  • A near-infrared spectroscopy sensor, developed by University of British Columbia spine surgeon Brian Kwon, co-principal investigator, and commercialized by Pathonix Innovations Inc., to assess blood oxygenation and blood flow at the site of spinal injury
  • A fully implantable mean arterial pressure sensor that will be developed by a team of scientists including Aaron Phillips at the University of Calgary, Dane Grasse at Teliatry and Andrew Schimmoeller at Battelle
  • A system to stimulate the spinal cord and regulate blood pressure developed by Courtine and his team at EPFL, which is being commercialized by GTX Medical.

Together, these technologies will integrate into a system-of-systems that monitors the information from sensors and stimulators to allow clinicians to monitor patients鈥 progress. At the same time, the team will be able to identify the optimal time to transplant the neural stem cells and 3D scaffold in this critical time period after injury.

鈥淚t is exciting to lead this talented team of international scientists and to be in a position to effect real change for people who sustain a spinal cord injury,鈥 Moxon said. 鈥淚t鈥檚 this type of team science between academia and industry that makes clinical breakthroughs possible in short time periods.鈥

Development of the proposal for the award was facilitated by the 新澳门六合彩内幕信息 Davis Office of Research鈥檚 Interdisciplinary Research Support team and Gabriela Lee, project manager. This project is part of a larger effort at 新澳门六合彩内幕信息 Davis led by Moxon, Professor Sanjay Joshi in the Department of Mechanical and Aerospace Engineering, and Professor Carolynn Patten in the School of Medicine and College of Biological Sciences to develop a neuroengineering program that aims to restore, augment and extend human capacity to benefit society.
