BACKGROUND Tissue-engineered nerve scaffolds hold great potential in bridging large peripheral nerve defects. However, insufficient vascularization of nerve scaffolds limited neural tissues survival and regeneration, which hampered the successful implantation and clinical application of nerve scaffolds. The omentum possesses a high vascularization capacity and enhances regeneration and maturati...

Prolonged intermittent-sprint exercise (i.e., team sports) induce disturbances in skeletal muscle structure and function that are associated with reduced contractile function, a cascade of inflammatory responses, perceptual soreness, and a delayed return to optimal physical performance. In this context, recovery from exercise-induced fatigue is traditionally treated from a peripheral viewpoint,...

Hearing loss caused by cochlear hair cell loss is the most common process afflicting the hearing impaired. Recent studies in the avian cochlea following ototoxic drug and noise damage have demonstrated a remarkable capacity for anatomical and functional recovery. Hair cell regeneration has been shown to play a major role in this recovery process. Future studies may one day make hair cell regene...

Background In patients with acute liver failure (ALF) who fulfil criteria, liver transplantation is the only effective treatment which can substitute metabolic and excretory function of the liver. Auxiliary liver transplantation was developed because a significant minority of patients with ALF who fulfil transplant criteria can have a complete morphological and functional recovery of their live...

The aim of this study was to evaluate the effect of bone marrow-derived mesenchymal stromal cell (BM-MSC) administration on liver function following partial hepatectomy (PHx) of methionine/choline-deficient (MCD) diet induced steatotic livers in rodents. Here we identified and validated serum cholinesterase (CHE) and triglyceride (TG) levels as non-invasive markers to longitudinally monitor rat...

Despite the potential importance that synapse regeneration plays in restoring neuronal function after spinal cord injury (SCI), even the most basic questions about the morphology of regenerated synapses remain unanswered. Therefore, we set out to gain a better understanding of central synapse regeneration by examining the number, distribution, molecular composition, and ultrastructure of regene...

Recovery from spinal cord injury (SCI) after mesenchymal stem cells (MSCs) implantation is minimal due to the limited capacity for the reduction in the cystic cavitation, the axonal regeneration, and neural plasticity in the spinal cord. We combined MSC implantation with neurotrophin gene therapy in an attempt to enhance regeneration and functional recovery after thoracic spinal cord complete i...

Rapid regeneration of the visual pigment following its photoactivation is critical for the function of cone photoreceptors throughout the day. Though the reactions of the visual cycle in the retinal pigment epithelium (RPE) that recycle chromophore for rod pigment regeneration are well characterized, the corresponding mechanisms that enable rapid regeneration of cone pigment are poorly understo...
