Neuronal Differentiation of Human Mesenchymal Stromal Cells Increases their Resistance to Aβ42 Aggregate Toxicity

Abstract

Cell therapy is a promising approach for the treatment of neurodegenerative conditions such as Alzheimer's and Parkinson's diseases. However, the presence of toxic aggregates in tissue raises the question of whether grafted stem cells are susceptible to amyloid toxicity before they differentiate into mature neurons. To address this question, we investigated the relative vulnerability of human mesenchymal stromal cells and their neuronally differentiated counterparts to Aβ(42) oligomers and whether susceptibili…
