background: effects of platelet-derived growth factor b (pdgf-b) on peripheral nerve regeneration was studied using a rat sciatic nerve transection model. materials and methods: forty‑five male, white wistar rats were divided into three experimental groups (n = 15), randomly: normal control group (nc), silicon group (sil), and pdgf‑b treated group (sil/pdgf). in nc group, left sciatic nerve was...

Injury to nerve tissue in the peripheral nervous system (PNS) results in long-term impairment of limb function, dysaesthesia and pain, often with associated psychological effects. Whilst minor injuries can be left to regenerate without intervention and short gaps up to 2 cm can be sutured, larger or more severe injuries commonly require autogenous nerve grafts harvested from elsewhere in the bo...

Novel approaches attempt to provide an alternative to autologous nerve graft. Nerve guidance conduit (NGC) have been designed to bridge the gap and provides guidance for sprouting axon and provide a place for diffusion of neurotropic factors and endogenous/transplanted cells at the lesion site [2]. It is believed that an ideal nerve conduit should provide not only structural support for damaged...

Background: Peripheral nerve injury is one of the most challenging of modern surgical problem. Recent advances in understanding the physiological and molecular pathways demonstrated the important role of growth factors in peripheral nerve regeneration. Platelet-rich plasma (PRP) is a biological product that has many growth factors. The aim of this study was to investigate the effect of PRP in t...

End-to-end neurorrhaphy remains the gold standard for transected nerve repair. However, the current dogma is that to be successful, nerve repairs must be tension free. Therefore, nerve gaps are most commonly repaired with grafts. While there is evidence that nerves can regenerate successfully after initial approximation under a tensile force, the amount of tension that deters regeneration of hu...

Peripheral nerve injuries are common, and there is no easily available formula for successful treatment. Incomplete injuries are most frequent. Seddon classified nerve injuries into three categories: neurapraxia, axonotmesis, and neurotmesis. After complete axonal transection, the neuron undergoes a number of degenerative processes, followed by attempts at regeneration. A distal growth cone see...

Damage to the peripheral nervous system is surprisingly common and occurs primarily from trauma or a complication of surgery. Although recovery of nerve function occurs in many mild injuries, outcomes are often unsatisfactory following severe trauma. Nerve repair and regeneration presents unique clinical challenges and opportunities, and substantial contributions can be made through the informe...

Nerve degeneration after transection injury decreases intraoperative visibility under white light (WL), complicating surgical repair. We show here that the use of fluorescently labeled nerve binding probe (F-NP41) can improve intraoperative visualization of chronically (up to 9 months) denervated nerves. In a mouse model for the repair of chronically denervated facial nerves, the intraoperative...
