Abstract
Previous studies suggest that the delivery of neurotrophic factors secreted from adipose stromal cells (ASC) protect the brain from 6-hydroxydopamine (6-OHDA)-induced neurotoxicity. However, it remains unclear which secreted neurotrophic factor has an important role in protecting 6-OHDA-treated neurons. Through the use of antibodies in this study, we demonstrated that specific neutralization of IGF-1 activity in ASC conditioned media (ASC-CM) significantly blocks ASC-CM-induced neuroprotection against 6-OHDA neurotoxicity. Consistently, this neuroprotection was mostly attributed to the activation of the AKT-mediated signaling pathway. In contrast, brain derived neurotrophic factor (BDNF), glial-derived neurotrophic factor (GDNF), vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF) in ASC-CM did not play a role in ASC-CM-induced neuroprotection against 6-OHDA.
