Astrocytes are glial cells The control group was SVG P12 cells without exosomes treatment, and the experimental group was SVG P12 cells co-cultured with exosomes of H1299 cells for 24h. The differences in protein expression between the two groups were compared. Primary human astrocytes were transfected with the SV40 T antigen expression vectors, pSV3neo or p735.6, and cultures were established with an extended lifespan. When co-cultured with neuronal cells, HASTR/ci35 cells could facilitate their dendritic network formation. This microenvironment is the fundamental factor for the construction of PMN and could further promote the dynamic evolution of PMN and the subsequent invasion of tumor cells to target organs [23, 24]. Kremlev SG, Gaurnier-Hausser AL, Del Valle L, et al. At last, the Bio-Plex detector was used to detect the concentration of each sample.
