To address the question of whether deployment and function of lamprey cognates of gnathostome neural crest genes are evolutionarily conserved, we performed moderate-throughput transcriptome analysis, identifying more than 50 genes involved in neural crest formation in lamprey.
Myelin basic proteins (MBPs) are abundant in the myelin sheaths of gnathostome central nervous system (CNS) and peripheral nervous system (PNS) (Waehneldt et al.
Because these two species have independent evolutionary histories covering hundreds of millions of years, mRNAs common to OL processes in both species likely represent proteins recruited to form the original myelin sheaths in the common gnathostome ancestor.
