CAS Slowly proliferating foci with several morphologies appeared 4 months after initiation of the cultures and became progressively enriched by cells with a homogeneous appearance. 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]. The Society for In Vitro Biology (SIVB) was founded in 1946 as the Tissue Culture Association to foster exchange of knowledge of in vitro biology of cells, tissues and organs from both plant and animals (including humans).

From Fig. In recent years, tumor cell-derived exosomes have attracted extensive attention as intercellular communication materials. An official website of the United States government. The blood-brain barrier and blood-tumour barrier in brain tumours and metastases. However, the effect of lung cancer cell-derived exosomes on astrocytes during the formation of brain PMN in lung cancer brain metastasis had not been reported so far. Therefore, we co-cultured exosomes of non-small cell lung cancer (NSCLC) cell line H1299 with human astrocytes to explore their effects on astrocytes and reveal the role of lung cancer cell-derived exosomes on the formation of brain PMN. All the human SV40-derived lines retained morphological features and growth properties of type 1 astrocytes. Astrocytes are glial cells found in the brain and spinal cord that play a critical role in maintenance, support, and repair of nervous tissue. Therefore, our results suggest that the age-associated upregulation of GS and GLT-1 is a conserved feature between mouse and human hippocampal astrocytes.
