Stem Cell Transplanting Treatment for Alzheimer’s Disease
Currently, cell‑based therapy has been demonstrated to be a promising approach for many kinds of diseases including AD.
Stem cell‑derived neurons have demonstrated a great potential in integrating with the neural networks of the brain. Thus, the effective cell treatment of AD require the stem cells to exhibit targeted migration toward the damaged regions of the brain and then differentiate into multiple subtypes of neural cells.[38] Stem cells include NSCs, embryonic stem cells (ESCs), MSCs, and induced pleuripotent stem cells (iPSCs). It has also been proven that symptoms of AD could be alleviated by transplanting MSCs derived from the human umbilical cord into the brains in transgenic mouse models where Aβ‑aggregation has been observed.[39] Furthermore, human umbilical cord blood‑derived MSCs (UCB‑MSC) are currently in phase I clinical trial. It is worth noting that NSC transplantation can reduce neuronal loss and improve cognitive function by increasing acetylcholine levels,and secrete neurotrophic factors to enhance/regulate synaptic plasticity in animal models of AD.[40‑42]
