"We are excited to be working alongside the Reeve Foundation, a recognized leader in the field of spinal cord injury, to advocate for treatments and support for those affected by paralysis. Creating and presenting an investor-facing event like the SCIIS is an opportunity to highlight the important work being done by for-profit and non-profit organizations alike," stated Brian M. Culley, Lineage CEO. "Our aim at Lineage is to improve recovery and mobility by replacing the cells which are destroyed following a spinal cord injury. We are encouraged by the initial clinical testing which has been performed with our approach and look forward to continuing our work. We also intend to increase our engagement with patients and the advocacy community as part of our broader efforts to improve outcomes for those affected by this debilitating condition. In certain rare disease settings, we have seen that raising investor awareness can lead to greater investment, which can accelerate new treatments. This symposium aims to offer investors and potential partners a forum to discuss innovation and recent discoveries in the treatment of spinal cord injury."

"Recent scientific and technological breakthroughs are ushering in a new era in spinal cord injury research, and we're excited to partner with Lineage on the first annual SCIIS to share this important work. This symposium helps support a comprehensive infrastructure for expanded spinal cord injury research and provide new opportunities for engaged investors," said Marco Baptista Ph.D., Chief Scientific Officer at the Reeve Foundation. "By bringing together critical communities – scientists, industry members, and individuals and families impacted by spinal cord injury, to name a few – we hope to generate new partnerships to rapidly increase innovation and the number of treatments with the potential to change what it means to be living with spinal cord injury."

The 1^st Annual Spinal Cord Injury Investor Symposium will be held in-person, on June 29, 2023, in the Duane Roth Auditorium at the Sanford Consortium for Regenerative Medicine in La Jolla, CA. This event will bring together both public and private companies developing new treatment options for people with spinal cord injury, alongside leaders in the spinal cord injury medical and advocacy communities. A number of important topics will be discussed, including current treatment approaches, the impact of SCI, SCI clinical trial participation and ensuring persons with lived experience perspectives, needs & priorities are appropriately captured, including with new clinical assessment tools. Advance registration is required for attendance.

About Spinal Cord Injuries

A spinal cord injury occurs when the spinal cord is subjected to a severe crush or contusion and frequently results in severe functional impairment, including limb paralysis, aberrant pain signaling, and loss of bladder control and other body functions. There are approximately 18,000 new spinal cord injuries annually in the U.S. The cost of a lifetime of care for a severe spinal cord injury can be as high as $5 million.

About the Sanford Consortium for Regenerative Medicine

The mission of Sanford Consortium for Regenerative Medicine is to advance stem cell research through collaborative, multi-disciplinary interactions. This "collaboratory" enables scientists from the La Jolla Institute for Allergy & Immunology, the Salk Institute for Biological Studies, the Sanford Burnham Prebys Medical Discovery Institute, Scripps Research, and the University of California, San Diego to work side by side in a facility specifically designed to achieve breakthrough discoveries. Consistent with the objectives of the California Institute for Regenerative Medicine, Sanford Consortium for Regenerative Medicine researchers are applying the powers of stem cells to promote diagnoses, treatments, and cures for degenerative diseases and injuries. In December 2011, the Sanford Consortium for Regenerative Medicine brought together researchers from the collaborating organizations under a single roof in a new world-class facility, funded in large part through a $43 million major facilities grant award from the California Institute for Regenerative Medicine (CIRM). The facility, centrally located among the five member institutions, is enabling scientists to share intellectual capital so that research may progress in a faster, smarter and more effective manner. In addition to shaping advances in stem cell science, the Sanford Consortium for Regenerative Medicine is committed to nurturing the next generation of scientific leaders.
