On regeneration and collateral sprouting to hind limb digits after sciatic nerve injury in the rat

Description: This study examines the proportions of regenerative and collateral sprouting to the skin after peripheral nerve injury. Methods: In the first experimental paradigm, primary afferent neurones were pre-labelled with Diamidino Yellow (DY), injected in digit 3, followed by sciatic nerve section and repa...

Persistence of tracer in the application site -a potential confounding factor in nerve regeneration studies

Description: Selective reinnervation of peripheral targets after nerve injury might be assessed by injecting a first tracer in a target before nerve injury to label the original neuronal population, and applying a second tracer after the regeneration period to label the regenerated population. However, altered u...

Sciatic and femoral nerve sensory neurones occupy different regions of the L4 dorsal root ganglion in the adult rat.

Description: The topographical distribution of sciatic and femoral nerve sensory neuronal somata in the L4 dorsal root ganglion of the adult rat was mapped after retrograde tracing with one or two of the dyes Fast Blue, Fluoro-Gold, or Diamidino Yellow. The tracers were applied to the proximal transected end of ...

Efficacy of the fluorescent dyes Fast Blue, Fluoro-Gold, and Diamidino Yellow for retrograde tracing to dorsal root ganglia after subcutaneous injection

Description: The present study was designed to investigate the efficacy of the fluorescent dyes Fast Blue (FB), Fluoro-Gold (FG), and Diamidino Yellow (DY) for retrograde tracing of lumbar dorsal root ganglia after their subcutaneous injection into different hindlimb digits. Injection of equal volumes (0.5 mu l)...

Fast Blue and Diamidino Yellow as retrograde tracers in peripheral nerves: efficacy of combined nerve injection and capsule application to transected nerves in the adult rat

Description: Capsule application of Diamidino Yellow (DY) to the cut end of the sciatic nerve immediately followed by capsule application of Fast Blue (FB) resulted in approximate to 95% double-labelled dorsal root ganglion neurones (DRGn) and motoneurones (Mn). Nerve injection of DY followed either immediately ...

Contribution of femoral and proximal sciatic nerve branches to the sensory innervation of hindlimb digits in the rat

Description: The present study was performed to investigate the possibility of 'aberrant' innervation of the tips of the hindlimb digits in the rat, i.e., from other sources than the femoral and the main sciatic branches (tibial, peroneal, sural). Cutaneous injections of fluorescent tracers in the digits were co...

Estimations of topographically correct regeneration to nerve branches and skin after peripheral nerve injury and repair.

Description: Peripheral nerve injury is typically associated with long-term disturbances in sensory localization, despite nerve repair and regeneration. Here, we investigate the extent of correct reinnervation by back-labeling neuronal soma with fluorescent tracers applied in the target area before and after sci...

Representations of hindlimb digits in rat dorsal root ganglia

Description: The distribution in dorsal root ganglia of neurones that innervate the distal tips of the hindlimb digits in the rat were mapped after subcutaneous injections of the fluorescent tracers Fast Blue, Diamidino Yellow, and Fluoro-Gold into different digits. Three-dimensional reconstruction was used to d...

Cryostat slice irregularities may introduce bias in tissue thickness estimation: relevance for cell counting methods

Description: Stereological techniques using the optical disectors require estimation of final section thickness, but frozen tissue irregularities may interfere with this estimation. Cryostat slices from rodent nerve tissues (dorsal root ganglia, spinal cord, and brain), cut at 16, 40, and 50 μm, were digitized w...
