Bone marrow-derived mesenchymal stem cells reduce brain amyloid-β deposition and accelerate the activation of microglia in an acutely induced Alzheimer's disease mouse model

Abstract

The therapeutic potential of bone marrow-derived mesenchymal stem cells (BM-MSCs) has recently been explored in various pathological conditions of the central nervous system (CNS). However, the application of BM-MSCs in acutely induced Alzheimer's disease (AD) has not yet been reported. Herein the feasibility of using the BM-MSCs, as a therapeutic agent for AD has been tested. To assess this possibility, an acutely induced AD model induced by injecting amyloid-beta (Abeta) into the dentate gyrus (DG) of hippocampus of C57BL/6 mice was used. Intracerebral transplantation of BM-MSCs into the brain of an induced AD model reduced their Abeta levels when compared to sham-transplanted animals. The diminution of Abeta deposits was accompanied by the activation of microglia. In addition, the activated microglia was located near the Abeta deposits, and their morphology was changed from ramified to ameboid as a sign of microglial phagocytosis. This study provides evidence that BM-MSCs can promote the reduction of Abeta through the microglial activation in this acutely induced AD brain, suggesting a potential therapeutic agent against AD.

  • BM-MSCs can accelerate microglia activation, reduce amyloid-β deposition and ameliorate cognitive abilities in AD mouse models.

    “In AD treatment, the MSCs bone marrow-derived (BM-MSCs) are particularly interesting since they can accelerate microglia activation, reduce amyloid-β deposition and ameliorate cognitive abilities in AD mouse models [171].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
