Introduction: Stem cell therapy can promote good recovery from stroke. Several studies have demonstrated that
mesenchymal stem cells (MSC) are safe and effective. However, more information regarding appropriate cell type is
needed from animal model. This study was targeted at analyzing the effects in ischemic stroke of acute
intravenous (i.v.) administration of allogenic bone marrow- (BM-MSC) and adipose-derived-stem cells (AD-MSC) on
functional evaluation results and brain repair markers.
Methods: Allogenic MSC (2 × 106 cells) were administered intravenously 30 minutes after permanent middle
cerebral artery occlusion (pMCAO) to rats. Infarct volume and cell migration and implantation were analyzed by
magnetic resonance imaging (MRI) and immunohistochemistry. Function was evaluated by the Rogers and rotarod
tests, and cell proliferation and cell-death were also determined. Brain repair markers were analyzed by confocal
microscopy and confirmed by western blot.
Results: Compared to infarct group, function had significantly improved at 24 h and continued at 14 d after i.v.
administration of either BM-MSC or AD-MSC. No reduction in infarct volume or any migration/implantation of cells
into the damaged brain were observed. Nevertheless, cell death was reduced and cellular proliferation significantly
increased in both treatment groups with respect to the infarct group. At 14 d after MSC administration vascular
endothelial growth factor (VEGF), synaptophysin (SYP), oligodendrocyte (Olig-2) and neurofilament (NF) levels were
significantly increased while those of glial fiibrillary acid protein (GFAP) were decreased.
Conclusions: i.v. administration of allogenic MSC - whether BM-MSC or AD-MSC, in pMCAO infarct was associated
with good functional recovery, and reductions in cell death as well as increases in cellular proliferation,
neurogenesis, oligodendrogenesis, synaptogenesis and angiogenesis markers at 14 days post-infarct
