Neurocritical care

Transplantation of bone marrow or adipose-derived mesenchymal stem cells (MSCs) for various neurological disorders has yielded promising results in models of focal cerebral ischemia. Dental pulp stem cells (DPSCs) are a type of MSC. In serum-free culture, they can form neurospheres that contain nestin-positive neuronal progenitor cells. We hypothesized that transplantation of dental pulp-derived neurosphere cells would ameliorate outcomes of global cerebral ischemia, the pathophysiology of which is known to resist conventional treatments. We also hypothesized that transplantation of dental pulp-derived cells would provide some neuroprotection in this pathology due to the presence of DPSCs. ⋯ Transplantation of dental pulp-derived neurosphere cells ameliorated outcomes of global cerebral ischemia. It was also demonstrated that dental pulp-derived cell administration provided some neuroprotection.
