Methods The guts of embryonic mice removed and dissociated were plated into serum-free DMEM/F12 medium. The mitogen-free DMEM/F12 medium supplementd with 10% fetal bovine serum was used to induce differentiation of GNCSCs. Neurospheres and their derivations were determined with immunocytochemical and immunofluorescent staning.
