摘要
The delivery of factors secreted by adipose stromal cells (ASC) to the brain may be a viable neuroprotective therapeutic option. In this study, we investigated the bioactivity of ASC-conditioned medium (ASC-CM) in glutamate-induced neurotoxicity and found that the ASC-CM significantly blocked glutamate neurotoxicity. We identified the brain-derived neurotrophic factor (BDNF) in the ASC-CM by using Western blot and demonstrated that this activity was critical for the neuroprotective effect of ASC-CM in excytotoxicity models. Furthermore, inactivating BDNF also attenuated the suppression by ASC-CM of glutamate-induced caspase-3 activity, but not p38 phosphorylation. These findings suggest that among ASC secrete a potent combination of factors, BDNF play a major role in neuroprotection against excytotoxicity. (c) 2009 Elsevier Ireland Ltd. All rights reserved.
