In some studies, screening blood tests are needed prior to enrollment. Patients with blockage of the cerebral arteries within the skull and symptoms within 3 months of their most recent symptom are eligible for enrollment. Patients must have experienced a stroke and be enrolled within 3 months of symptom onset. A blood test must be performed to determine whether the candidate has an elevated homocysteine level. An immortalized neuronal cell line will be tested in patients with chronic stroke.
Preliminary studies suggest that the neuronal graft is viable.
Twelve individuals are anticipated to participate. A number of different studies are currently in progress.
