Is Multifocality an Indicator of Aggressive Behavior in Small Bowel Neuroendocrine Tumors?

abstract：:Fetal and neonatal pancreatic islets have lower insulin secretory responses compared with adult islets. In culture conditions and after treatment with mammosomatotropic hormones, neonatal islets undergo maturation of the secretory machinery that might involve regulation of cell-cell contacts within the islet. This stu...
