The "Waiting Period" of Sensory and Motor Axons in Early Chick Hindlimb: Its Role in Axon Pathfinding and Neuronal Maturation

Guoying Wang, Sheryl A. Scott
2000 Journal of Neuroscience  
Therefore, axons do not require a prolonged period in the plexus region to sort out and project appropriately.  ...  Thus, axons wait in the plexus region for maturational changes to occur in the limb rather than in the neurons themselves.  ...  regulatory mechanisms are far from understood.  ...

Independent Development of Sensory and Motor Innervation Patterns in Embryonic Chick Hindlimbs

Guoying Wang, Sheryl A. Scott
1999 Developmental Biology  
The resulting sensory innervation patterns mapped with the lipophilic dyes DiI and DiA showed that sensory axons projected robustly to muscles in the absence of motoneurons, if motoneurons were eliminated  ...  Moreover, sensory neurons projected appropriately to their usual target muscles under these conditions.  ...  Note that sensory projection patterns are indistinguishable from those in Fig. 7. survive, apparently because they project to ectopic targets nearby (Calderó et al., 1998) .  ...

Ectoderm removal prevents cutaneous nerve formation and perturbs sensory axon growth in the chick hindlimb

Marcia G Honig, Suzanne J Camilli, Qing-Shan Xue
2004 Developmental Biology  
These results demonstrate that the target ectoderm is necessary for normal sensory axon growth and guidance in the hindlimb. D  ...  A few days later, when the nerve pattern is mature, axons normally destined for the 'deprived' cutaneous nerve are not segregated appropriately within the plexus.  ...  Initial LFCt nerve formation The absence of the LFCt nerve at St. 30 could, in theory, have been due to the failure of that nerve to form.  ...
