Astrocytes are glial cells found in the brain and spinal cord that play a critical role in maintenance, support, and repair of nervous tissue. Western Blot showed that the extracted exosome-positive protein markers CD9, Tsg101, and CD63 were expressed, while the negative-protein marker Calnexin did not expressed (Fig. Cagney DN, Martin AM, Catalano PJ, et al. Astrocytes are the most abundant cells in the central nervous system where they perform many functions, such as providing mechanical support and nutrients to neurons and removal of wastes from neurons; providing signaling to endothelial cells; regulating neurogenesis and controlling synaptic function. The name of each GO function was displayed in the vertical axis, and the value in horizontal axis was the P value after -log10 conversion. First, the collected cell supernatant of each group was centrifuged, and the standard sample was prepared according to the instructions. Melanoma-derived exosomes alter the metabolic activity of stromal fibroblasts by increasing aerobic glycolysis and decreasing oxidative phosphorylation, therefore leading to extracellular acidification of microenvironment cells at the metastatic site [31].
