AIMS: To examine whether transplantation of adipose-derived stem cells (ADSCs) induces neural differentiation and improves neural function in a rat intracerebral hemorrhage (ICH) model.
METHODS: Adipose-derived stem cells cells were isolated from inguinal fat pad of rat. ICH was induced by injection of collagenase type IV into the right basal ganglia of rat. Forty-eight hours after ICH, ADSCs cells (10 μL of 2-4 × 10(7) cells/mL) were injected into the right lateral cerebral ventricle. The differentiation of ADSCs was detected in vitro and in vivo. The neural function was evaluated with Zea Longa 5-grade scale at day 1, 3, 7, 14, or 28.
RESULTS: Our data demonstrated that ADSCs differentiated into cells that shared the similarities of neurons or astrocytes in vitro. Transplantation of ADSCs decreased cell apoptosis and the transplanted ADSCs were able to differentiate into neuron-like and astrocyte-like cells around the hematoma, accompanied with upregulation of vascular endothelial growth factor expression and improvement of neural function.
CONCLUSIONS: Our data suggest that transplantation of ADSCs could be a therapeutic approach for ICH stroke.
