Growth Factor	Function
GDNF	Neuroprotection, regulate inflammation, Differentiation, proliferation, migration, neurite outgrowth and synaptic plasticity
VEGF	Angiogenesis and neuroprotection
SDF-1	Cell signaling, anti-inflammation, anti-apoptosis, migration, and chemotaxis
SCF	Differentiation, neurogenesis, neuroprotection, chemotaxis, and Migration
BDNF	Neuronal survival, synaptic function, anti-inflammation, and anti-apoptosis
