Injectable Hydrogel System for the Treatment of Stroke and Nervous Tissue Injury

Over 1.7 million Americans in the US sustain traumatic brain injury (TBI) each year[1] and an estimated 3.2 million Americans have long term disabling effects from TBI[2].  This novel and effective technology features an injectable biomaterial gel with the ability to promote functional tissue regeneration at the site of a traumatic brain injury and stroke. The technology provides a procedure whereby the hydrogel is injected into a lesion in the brain that will direct the response of neural stem cells in the brain to regenerate normal brain tissue at the lesion site. This technology provides a potential alternative, beneficial approach to the current methods used to treat traumatic brain injuries which focus on managing the primary injury using hypothermia or neuro-protection with pharmacological agents.  Research using this material has demonstrated revascularization of the lesion sites and sustained recovery in rats with CNS injuries. 

Applications:

· Traumatic Brain Injury Repair

· Repair of brain lesions due to stroke

· Repair of spinal cord lesions

Benefits:

· Injectable, acellular therapy that recruits native cells and promotes functional tissue regeneration 

· Alternative approach to current methods used to treat traumatic brain injuries that employ hypothermia or neuroprotection with pharmacological agents
