GAP43 and neuroblastoma: Human neuroblastoma cell line (SH-SY5Y) showed distinct expression of all of these genes except MBP. In contrast, human abdominal adipose-derived MSCs at passage 4 did not significantly express all of the above genes except CNPase, TUBB3 and GAP43. Immunocytochemical analyses further confirmed that hEASCs at passage 8 spontaneously expressed a variety of neural-related markers including Nestin, GFAP, APC, MAP2, galactocerebroside (Galac), DOPA and GAP43, in addition to the mesoderm/endoderm-specific marker Vimentin (Fig. 2B).
