OBJECTIVE: This study investigates the role of a burr hole and calvarial bone
marrow-derived stem cells (BMSCs) in a transient ischemic brain injury model in
the rat and postulates a possible mechanism for the efficacy of multiple cranial
burr hole (MCBH) surgery in moyamoya disease (MMD). METHODS: Twenty
Sprague-Dawley rats (250 g, male) were divided into four groups : normal control
group (n=5), burr hole group (n=5), ischemia group (n=5), and ischemia+burr hole
group (n=5). Focal ischemia was induced by the transient middle cerebral artery
occlusion (MCAO). At one week after the ischemic injury, a 2 mm-sized cranial
burr hole with small cortical incision was made on the ipsilateral (left)
parietal area. Bromodeoxyuridine (BrdU, 50 mg/kg) was injected intraperitoneally,
2 times a day for 6 days after the burr hole trephination. At one week after the
burr hole trephination, brains were harvested. Immunohistochemical stainings for
BrdU, CD34, VEGF, and Doublecortin and Nestin were done. RESULTS: In the
ischemia+burr hole group, BrdU (+), CD34 (+), and Doublecortin (+) cells were
found in the cortical incision site below the burr hole. A number of cells with
Nestin (+) or VEGF (+) were found in the cerebral parenchyma around the cortical
incision site. In the other groups, BrdU (+), CD34 (+), Doublecortin (+), and
Nestin (+) cells were not detected in the corresponding area. These findings
suggest that BrdU (+) and CD34 (+) cells are bone marrow-derived stem cells,
which may be derived from the calvarial bone marrow through the burr hole. The
existence of CD34 (+) and VEGF (+) cells indicates increased angiogenesis, while
the existence of Doublecortin (+), Nestin (+) cells indicates increased
neurogenesis. CONCLUSION: Based on these findings, the BMSCs through burr holes
seem to play an important role for the therapeutic effect of the MCBH surgery in
MMD.
