FGF2 and hereditary pheochromocytoma-paraganglioma: The ECM-binding capacity of EBP-bFGF was detected through enzyme-linked immunosorbent assay (ELISA), and the bioactivity of EBP-bFGF was measured through the proliferative assay of human skin fibroblast cells (HSFCs), the survival of pheochromocytoma cells (PC cells) in vitro and subcutaneous embedding in vivo.
