Fibrin gels containing GDNF microspheres increase axonal regeneration after delayed peripheral nerve repair.
AIM Recovery following nerve transection declines when target reconnection is delayed for prolonged periods. GDNF has previously been shown to promote motor axon regeneration following delayed nerve repair. MATERIALS & METHODS We constructed delivery systems using fibrin gels containing free GDNF or poly(lactide-co-glycolide) microspheres with GDNF. The delivery systems were implanted with fl...
متن کاملTransplantation of Olfactory Mucosa Improve Functional Recovery and Axonal Regeneration Following Sciatic Nerve Repair in Rats
Background: Olfactory ensheathing glia (OEG) has been shown to have a neuroprotective effect after being transplanted in rats with spinal cord injury. This study was conducted to determine the possible beneficial results of olfactory mucosa transplantation (OMT) which is a source of OEG on functional recovery and axonal regeneration after transection of the sciatic nerve. Methods: In this study...
متن کاملAbnormal regenerative responses and impaired axonal outgrowth after nerve crush in TDP-43 transgenic mouse models of amyotrophic lateral sclerosis.
Tar DNA binding protein 43 (TDP-43) mislocalization and aggregation is a hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar dementia. Moreover, TDP-43 mRNA was found to be upregulated by ∼2.5-fold in the spinal cord of sporadic ALS subjects. Here we have examined the effects of nerve injury in new transgenic mouse models overexpressing by approximately threefold wild-type ...
متن کاملExpression of activating transcription factor 3 (ATF 3) and caspase 3 in Schwann cells and axonal outgrowth after sciatic nerve repair in diabetic BB rats.
The aim of this study was to evaluate nerve regeneration in relation to the transcription factor, Activating Transcription Factor 3 (ATF 3), and an apoptotic marker, caspase 3, in the Schwann cells of diabetic BB rats (i.e. display type 1 diabetes phenotype). Sciatic nerves in healthy Wistar rats and in diabetic BB rats were transected and immediately repaired. Axonal outgrowth (neurofilament s...
متن کاملGDNF released from microspheres enhances nerve regeneration after delayed repair.
INTRODUCTION Delays in surgical repair following nerve transection produce progressively inferior motor nerve regeneration. Regeneration can be improved with delivery of exogenous growth factor. We developed a delivery system that could be applied at the nerve repair site to deliver growth factors locally to regenerating nerve. METHODS Poly(lactic-co-glycolic acid) microspheres containing gli...
