Potential Therapies by Stem Cell-Derived Exosomes in CNS Diseases: Focusing on the Neurogenic Niche

Figure 1

Animal models of CNS diseases (and memory processing) potentially linked to neurogenic niche alterations. Schematic representation of brain coronal slices and transverse section of spinal cord. Neurogenic niches are indicated in red lines and arrows. SVZ corresponds to subventricular zone; SGZ corresponds to subgranular zone; spinal cord central canal niche is also depicted. The reference number for each pathology associated with the neurogenic niche is indicated. References: PD [71]; Huntington [72]; stroke [73]; epilepsy (SVZ) [74]; MS (SVZ) [75]; memory [76]; stress [77]; stroke (SGZ) [73]; epilepsy (SGZ) [74]; MS (spinal cord central canal) [78]; ALS [79].
