...Shlomo Krispin; Erez Nitzan; Yachia Kassem; Chaya Kalcheim Colonization of trunk neural crest derivatives in avians follows a ventral to dorsal order beginning with sympathetic ganglia, Schwann cells, sensory ganglia and finally melanocytes. Continuous crest emigration underlies this process, which...

... the germline CREB mutant revealed increased apoptosis of NA neurons and misplacement of sympathetic precursors, the NA neuron-specific mutation unexpectedly led to reduced levels of caspase-3-dependent apoptosis in sympathetic ganglia during the period of naturally occurring neuronal death. A reduced level...

...Jennifer C. Kasemeier-Kulesa; Roger Bradley; Elena B. Pasquale; Frances Lefcort; Paul M. Kulesa Previous studies have suggested that the segmental pattern of neural-crest-derived sympathetic ganglia arises as a direct result of signals that restrict neural crest cell migratory streams through...

... sympathetic neurons. The average number of TH-positive neurons per section was calculated from around 20 serial frontal sections that were made at the cervical level of embryos at E12.5. Open and filled columns indicate the number of TH-positive neurons located at the original sites of the sympathetic ganglia...

... of the peripheral nervous system (PNS) to another metameric PNS component, the sympathetic ganglia (SG). The development of the primary sympathetic chain was studied in chick-quail chimeras with multiple half-somite grafts using quantitative morphometric analysis. In the presence of an exclusively rostral or caudal...
