Fig. 1From: RVG-modified exosomes derived from mesenchymal stem cells rescue memory deficits by regulating inflammatory responses in a mouse model of Alzheimer’s diseaseEnhanced engraftment of targeted exosomes derived from MSCs in the brain. The DiI-labeled exosomes were red and nuclei were counterstained with DAPI. The injected exosomes were detected in the cortex (a) and hippocampus (c) in both MSC-RVG-Exo group and MSC-Exo group. The number of injected exosomes was further compared by relative mean fluorescence intensity (b, d). **P < 0.01 versus the MSC-Exo group, by Student’s t-test; n = 3Back to article page
