Abstract (original English)
Background aims Adipose-derived stem cells (ADSCs) have shown great promise in the regenerative repair of injured peripheral nerves. Magnetic resonance imaging (MRI) has provided attractive advantages in tracking superparamagnetic iron oxide nanoparticle (SPION)-labeled cells and evaluating their fate after cell transplantation. This study investigated the feasibility of the use of MRI to noninvasively track ADSCs repair of peripheral nerve injury in vivo. Methods Green fluorescent protein (GFP)-expressing ADSCs were isolated, expanded, differentiated into an SC-like phenotype (GFP-dADSCs) at early passages and subsequently labeled with SPIONs. The morphological and functional properties of the GFP-dADSCs were assessed through the use of immunohistochemistry. The intracellular stability, proliferation and viability of the labeled cells were evaluated in vitro. Through the use of a microsurgical procedure, the labeled cells were then seeded into sciatic nerve conduits in C57/BL6 mice to repair a 1-cm sciatic nerve gap. A clinical 3-T MRI was performed to investigate the GFP-dADSCs in vitro and the transplanted GFP-dADSCs inside the sciatic nerve conduits in vivo. Results The GFP-dADSCs were efficiently labeled with SPIONs, without affecting their viability and proliferation. The labeled cells implanted into the mice sciatic nerve conduit exhibited a significant increase in axona
