Research summary
Role of guidance cues in peripheral nerve regeneration across acellular nerve allograft
My research focuses on the significant clinical challenge posed by peripheral nerve injuries (PNIs) with long-gap nerve defects. Currently, acellular nerve allografts (ANAs) are employed to aid regeneration, but they only support regeneration across short nerve gaps (<3 cm), failing to produce the desired results for longer gaps. I am interested in understanding the role of canonical nervous system guidance cues (Netrins, ephrins, Semaphorins, and Slits) in the repair mechanisms of these long-gap defects. My objective is to delve into the spatiotemporal expression profiles of these guidance cues and their receptors during the regeneration process, and subsequently alter the presentation of these cues within ANAs implanted in rodent models that simulate long-gap injuries in humans.
