Clonal permanent cell lines with astrocytic or microglial properties have been established from explant cultures of 8-day postnatal mouse cerebella after in vitro spontaneous transformation. Influence of Exosomes on Astrocytes in the Pre-Metastatic Niche of Lung Cancer Brain Metastases. When the cell density reached more than 90%, the cells were washed twice with PBS, and then the serum-free 1640 medium was added. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. During the brain metastasis process, tumor cells separated from the primary tumor enter the systemic circulation, stop at the branch of cerebral micro vessels, and then pass through the damaged BBB to reach the brain parenchyma [7]. Transport of y-amino butyric acid and glutamate were examined and found to be by a glial-specific mechanism, consistent with the cell lines' retaining aspects of normal glial function.

Article Activation of the cMet pathway mobilizes an inflammatory network in the brain microenvironment to promote brain metastasis of breast cancer. S1PR1-STAT3 signaling is crucial for myeloid cell colonization at future metastatic sites. Twenty four h after co-culture of H1299 cell-derived exosomes and SVG P12 cells, the viability of astrocytes decreased and the apoptosis increased. Exosomes of H1299 could induce apoptosis of astrocytes as well as promote their secretion of cytokines that were conducive to the formation of the inflammatory microenvironment and immunosuppressive microenvironment, and affect their metabolic pathways, thus facilitating the formation of pre-metastatic niche in lung cancer brain metastases.
