Key takeaways<\/p>\n

\u2022 The therapy uses tissue nanotransfection (TNT) developed at The Ohio State University to deliver genes to nerve grafts, resulting in better nerve regrowth, stronger muscles and improved function in treated mice.<\/p>\n

COLUMBUS, Ohio \u2013 Peripheral nerve injuries, often caused by traumatic events such as car accidents, falls or battlefield injuries, can leave patients with long-term weakness, numbness or loss of function. Despite surgery and advances in understanding and treating nerve injuries, many patients don’t get all their movement or feeling back. <\/p>\n

Scientists used TNT to deliver three specific genes (Etv2, Fli1 and Foxc2) that tell cells to help form new blood vessels. These genes were applied via a very quick electrical pulse to nerve grafts used during surgery in mice with severe nerve injuries.
\n\"Daniel“This study is the first to combine TNT with nerve graft surgery, and the results are promising. While healing nerves do need oxygen and nutrients, blood vessels do much more than just deliver supplies \u2014 they help guide and support the repair process. By helping the body quickly grow new blood vessels, our approach creates a healthier environment that allows nerves to heal more effectively,” said study senior author Daniel Gallego-Perez, PhD<\/a>, professor and Edgar C. Hendrickson Chair in Biomedical Engineering at Ohio State. Ana Salazar-Puerta, PhD, a postdoctoral researcher in Gallego-Perez’s lab, led the research.Results of the research, a collaboration between Ohio State’s Colleges of Medicine and Engineering, were published today in the journal Science Advances<\/a>.<\/p>\n

What did researchers find?<\/p>\n

\u2022 Nerves treated with TNT grew more blood vessels than untreated nerves.<\/p>\n

\u2022 The extra blood vessels helped nerves regrow and reconnect better.<\/p>\n

\u2022 Treated mice had better health outcomes compared to those that only had surgery. <\/p>\n

\u2022 The new blood vessels mostly came from fibroblast cells, which play a crucial role in wound healing and tissue repair.<\/p>\n

“We saw improvements not just under the microscope, but in real function like stronger muscle contractions and better grip strength,” said Amy Moore, MD<\/a>, chair of Ohio State’s Department of Plastic and Reconstructive Surgery<\/a>, interim dean of the College of Medicine and the Robert L. Ruberg, MD Alumni Endowed Chair.<\/p>\n

Researchers said the therapy could one day be applied during surgery, adding only a short step to existing procedures.<\/p>\n

“This is designed to fit into the operating room and is a single treatment that could have lasting benefits,” Salazar-Puerta said. <\/p>\n

What’s next?<\/p>\n

Next, researchers will test the method in larger animal models and study how long the benefits last. Ohio State has patented TNT and the gene “cocktail” to make blood vessels.<\/p>\n

Research funding primarily came from the U.S. Department of Defense as well as a grant from the National Institutes of Health. Moore noted that severe, complex nerve injuries are common among military service members injured in combat or training and can lead to lifelong disability. Ohio State’s Military Medicine Program<\/a> brings together a team of advanced reconstructive surgeons, military specialists and rehabilitation experts to help restore the health and well-being of severely injured military members.<\/p>\n
