Key Takeaways Doctors can deliver stem cells for spinal cord injury through several routes, each with different reach and risk. Intravenous delivery is the least invasive route, but few cells actually reach the injury site. Intrathecal delivery is the most studied route in human trials, and a recent review links
Key Takeaways Stem cell therapy after spinal cord injury is studied for both traumatic and chronic cases, with different goals at each stage. A 2024 study found durable motor and sensory improvements in some patients five years after neural stem cell transplantation. A 2026 trial reported no serious safety concerns
Key Takeaways Stem cell therapy for stroke is studied differently depending on timing. Acute and chronic stroke trials ask different questions. Most acute stroke research focuses on safety within the first days after a stroke, while chronic stroke trials often measure functional improvement months or years later. A landmark 2-year
Key Takeaways Traumatic brain injury (TBI) often causes lasting neurological deficits, since the brain has limited ability to repair itself after trauma. Stem cell therapy is being studied as a supportive treatment option that may calm inflammation and support the brain’s own repair signals. A Phase 2 controlled trial found
Key Takeaways Hypoxic brain injury is caused by reduced oxygen; anoxic brain injury by a complete stop. Both damage the same brain tissue but anoxic injuries tend to be more severe. Stem cell therapy supports recovery in both by releasing neurotrophic factors, reducing inflammation, and providing an environment for surviving
