Parkinsonian Brain Repair Using Human Stem Cells

"MRI-guided stereotactic intraputaminal cell implantation into PD patients was performed.~For target locations, measurements were made using CT-scan images fused with previous MR images. Bilateral parasagittal incisions and corresponding 14 mm burr holes were made in preparation for cell suspension injections.~To ensure complete cell suspension delivery, injections were carried out slowly for 2 min with reciprocal withdrawal of the delivery needle to avoid both damage to stem cells and brain tissue, as well as to avert reflux or bubble formation.~After surgery, patients were kept in a conventional post-operative care unit for 1 h. The day following surgery, MR images were obtained to confirm correct placement of cell suspensions. All patients were discharged 24 h after surgery."
