Abstract
In this study, we found that expression and secretion of galectin-3 (GAL-3) were upregulated by amyloid-beta42 (Abeta42) exposure in human umbilical cord blood-derived mesenchymal stem cell (hUCB-MSC) without cell death. Abeta42-exposed rat primary cortical neuronal cells co-treated with recombinant GAL-3 were protected from neuronal death in a dose-dependent manner. hUCB-MSCs were cocultured with Abeta42-exposed rat primary neuronal cells or the neuroblastoma cell line, SH-SY5Y in a Transwell chamber. Coculture of hUCB-MSCs reduced cell death of Abeta42-exposed neurons and SH-SY5Y cells. This neuroprotective effect of hUCB-MSCs was reduced significantly by GAL-3 siRNA. These data suggested that hUCB-MSC-derived GAL-3 is a survival factor against Abeta42 neurotoxicity. Copyright 2010 Federation of European Biochemical Societies. Published by Elsevier B.V.
