Encapsulated VEGF-Secreting Cells Enhance Proliferation of Neuronal Progenitors in the Hippocampus of AβPP/Ps1 Mice

Abstract

Vascular endothelial growth factor (VEGF) promotes neurogenesis in the adult hippocampus, but the way in which this process occurs in the Alzheimer's disease (AD) brain is still unknown. We examined the proliferation of neuronal precursors with an ex vivo approach, using encapsulated VEGF secreting cells, in AβPP/PS1 mice, a mouse model of AD. Overexpression of VEGF and VEGF receptor flk-1 was observed in the cerebral cortex from VEGF microcapsules-treated AβPP/PS1 mice at 1, 3 and 6 months after VEGF-microcap…
