Human Astrocytes Transfer Aggregated Alpha-Synuclein via Tunneling Nanotubes Many lines of evidence suggest that the Parkinson's disease (PD)-related government site. 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 corresponding protein concentration of exosomes was calculated according to the standard curve and the measured absorbance. Article 1321N1 is a human astrocytoma cell line isolated in 1972 as a sub clone of the cell line 1181N1 which in turn was isolated from the parent line U-118 MG (one of a number of cell lines derived from malignant gliomas by J Ponten .1321N1 has been shown to have very similar STR profile data to U-118 MG.

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. We present a three-dimensional induced pluripotent stem cell (iPSC)-derived paradigmmature brain organoids (mbOrg)composed of cortical-like-astrocytes (iA) and neurons.
