One week later each animal received five magnetic resonance (MR) image\u2013guided stereotactic intracerebral injections of HNSC neurospheres labeled with bromodeoxyuridine (BrdU) in the areas surrounding the ischemic lesion as defined in T\n                      <jats:sub>1<\/jats:sub>\n                      - and T\n                      <jats:sub>2<\/jats:sub>\n                      -weighted images. On the day of transplantation and throughout the study the monkeys received oral cyclosporine (10 mg\/kg twice a day), and plasma levels were monitored routinely. The animals were killed at 45, 75, or 105 days after transplantation. Magnetic resonance images revealed a cortical and subcortical infarction in the MCA distribution area. Postmortem morphological brain analyses confirmed the distribution of the infarcted area seen in the MR images, with loss of tissue and necrosis in the ischemic region. Cells that were positive for BrdU were present in the three experimental monkeys, mainly along injection tracks. Double-label immuno-fluorescence for BrdU and \u03b2III-tubulin (a marker of young neurons) revealed colocalization of few HNSCs, most of which were observed outside the immediate injection site. Colocalization with nestin was also observed, indicating an early neural\/glial fate.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
