Research Interest

• Electric fields guided brain neuron migration

Endogenous electrical signals are present in many developing systems and crucial cellular behaviours such as neuronal cell division, cell migration and cell differentiation are all under the influence of such endogenous electrical cues. Effectively directed neuron migration is critical for development and repair in the central nervous system. We recently demonstrated that small electric fields not only guide axonal growth, but also can direct the earlier events of neuronal migration and neuronal cell division. This raises the possibility that applied or endogenous electric fields, perhaps in combination, may direct transplanted neural stem cells, or regenerating neurons, to the desired site after brain injury or neuron degeneration. We are interested in investigating the mechanism of electric fields guided neuron migration and the solutions for the application of electric fields in guiding neuron migration in neurogenesis within the central nervous system.

• Spinal cord repair and regeneration

The limited functional improvement in in vivo models of spinal cord injury has prevented advancement of regenerative therapy to clinical use due to the multifaceted nature of spinal cord injuries. Biodegradable polymers can simultaneously provide structural guidance at a cellular level and a reservoir for sustained gene delivery. We are interested in developing the functionalised biomaterial scaffolds targeting injury mechanisms at the molecular, cellular and tissue levels of spinal cord injury.

• Peripheral nerve repair and regeneration

Axonal regeneration after injury or disease is the major challenge in both peripheral and central nervous system. In peripheral nerve regeneration, neural conduits have been investigated to bridge nerve defects. In our recent study, the advance in the design of engineered scaffolds that mimic peripheral nerve multiple basal lamina have improved guided axonal regeneration in vivo. Neural tissue engineering is a promising approach for axonal regeneration of critical nerve injury by preventing inhibitory factors and enhancing guided axonal growth.
