It has already been reported that human and mouse fibroblasts can be converted into cardiocytes[4], hepatocytes[5] and neurons[6] by transduction with defined factors. The mission is accomplished through the Society's publications; national and local conferences, meetings and workshops; and through support of teaching initiatives in cooperation with educational institutions. The results showed that CD9 and TSG 101 proteins were positively expressed on exosomes, while Calnexin proteins were negatively expressed. As the recognition of the importance of astrocytes in nervous system is increasing, HA serve as a useful in vitro model for exploring the diversity of astrocytes functions. Cite this article.

MeSH The name of each GO function was displayed in the vertical axis, and the value in horizontal axis was the P value after -log10 conversion. Astrocyte dysfunction is considered one of the pathological causes of many diseases including trauma, stroke and multiple sclerosis. GRO/CXCL1, IFN-, IL-3, IL-5, IL-15, LIF, M-CSF, NGF, PDGF, and VEGF were significantly increased, while the level of IL-7 was significantly decreased. Molecular functions related include NAD binding, electron transfer activity, ATP binding, and protein kinase regulator activity. We found that the cytokines secreted by astrocytes were significantly altered after treatment with tumor-derived exosomes. This suggested that the quality of extracted exosomes was up to the standard and could be used in subsequent experiments.

Previous studies have found that prior to metastasis, the primary tumor can reshape the microenvironment in a specific tissue and induce the formation of a pre-metastatic niche (PMN), which offers a valuable opportunity for the adaptation and survival of the primary tumor cells, enabling them to proliferate and obtain conditions for colonization in the target organ for subsequent metastasis [16]. An appropriate amount of PBS was added to suspend exosomes from the bottom of the centrifuge tube. Indeed, our 3D iPSC-induced cortical-like neuron and astrocyte co-culture with GRN loss strikingly and consistently recapitulated human specific TDP-43 cell pathology reported in human FTD patient brain.
