We conclude that methods based on the use of SV40 T antigen can successfully immortalize human astrocytes, retaining key astrocyte functions, but T antigen-induced proliferation appeared to interfere with expression of glial fibrillary acidic protein. 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]. Type I and II cells had small somata. 2017;67:310. The medium was replaced by serum-free 1640 medium as well as prepared exosome solution (80g/ml, 60g/ml, 40g/ml, 20g/ml).
