title: Sympathetic nervous system trophism for neuroblastoma and its age dependence in rats.
abstract: The sympathetic nervous system modulates the growth of C-1300 mouse neuroblastoma in vivo and in vitro. We now report that a mitogenic/trophic factor that augments growth of C-1300 neuroblastoma and of the S-20 neuroblastoma clonal line is present in freshly excised sympathetic cervical ganglia from newborn rats, but is not detectable in homogenates from sympathetic ganglia obtained from adult rats.
