Brief Summary
Evaluate the Safety and Efficacy of Exosomes Derived from Allogenic Adipose Mesenchymal Stem Cells（MSCs-Exos）in Subjects with Alzheimer's disease.
Detailed Description
To date, the main pathological characteristics of AD patients are the accumulation of β-amyloid (Aβ) into senile plaques, the abnormal aggregation of intracellular Tau protein to form neuron fiber tan...
