Delayed onset of midline netrin expression in Artemia franciscana coincides with commissural axon growth and provides evidence for homology of midline cells in distantly related arthropods
收藏 引用
EVOLUTION & DEVELOPMENT 2007年 第2期9卷 131-140页
作者: Duman-Scheel, Molly Clark, Stephanie M. Grunow, Eric T. Hasley, Andrew O. Hill, Brandon L. Simanton, Wendy L. Albion Coll Dept Biol Albion MI 49224 USA
Although many similarities in arthropod central nervous systems (CNS) development exist, differences in midline cell formation and ventral nerve cord axonogenesis have been noted in arthropods. It is possible that cha... 详细信息
