Propidium iodide stain was added into each EP tube and the tubes were incubated at room temperature away from light for 20minutes for detection. Watch our scientific video articles. 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. Therefore, lung cancer cell-derived exosomes could change astrocytes protein expression, affect their energy metabolism and accelerate the PMN formation in brain metastasis. Disclaimer. As an essential component of BBB, astrocytes are indispensable in the immune microenvironment for brain metastasis of lung cancer.

WebAstrocytes are non-neuronal brain cells that contribute to the exchange of neurotransmitters and ions. It has been found that cytokines secreted by tumor cells and host stromal cells can promote the formation of the local inflammatory microenvironment and immune inhibitory microenvironment. After centrifugation, the supernatant was transferred to a new tube, and an appropriate amount of exosome separation reagent was added, shaken, and mixed.

ZERO BIAS - scores, article reviews, Webexposed to sheer forces generated by shaking the cultures. Two hundred l BCA working solution was added to each hole and placed at 37C for 30minutes. 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].
