Project description:Extracellular microRNA sequences have attracted interest for their potential use as accessible biomarkers that may be non-invasively collected from a wide range of biological fluids, including spent culture media. The ongoing milieu between the late-stage preimplantation embryo and the receptive uterus remains an actively investigated area of research and the physiological role of secreted microRNA sequences remains to be determined. Spent culture media used to culture late stage E4.0 murine blastocysts was screened for 641 mature microRNA sequences using a qPCR-based array. We report here the 39 sequences that were exclusively detected in the conditioned media using this approach. The embryonic miR-290 family were among the most abundant extracellular sequences. Notably, implantation-relevant members miR-126a, miR-101a, miR-143 and miR-320 were also detected.
Project description:we examined the influence of Tc17-CM from WT or from IL17A/F KO mice on the in vitro differentiation of quiescent pancreatic stellate cells (qPSC) towards an iCAF or myCAF phenotypes
Project description:We performed DIA-MS based proteomic analysis of Hela cells conditioned media containing fetal bovine serum by albumin (Alb)-depletion and non-depletion. In addition, we attempted to enrich secreted proteins by reducing the volume of culture medium (10mL, 5mL and 2mL). The supernatants of each culture condition were subjected to albumin depletion followed by DIA-MS. We further analyzed proteins in the conditioned media of HeLa cells with and without tumor necrosis factor (TNF) stimulation.
Project description:The goal of this study is to compare the mRNA transcriptome of astrocytes treated with Activated Microglia and Endothelial conditioned media
Project description:Primary astrocyte cultures were prepared from wildtype and Gde3 knockout mouse brain. Conditioned media was collected, concentrated and analyzed using TMT-MS.
Project description:To identify the cytokines secreted by mesenchymal-like cancer cells that activate macrophages, the cytokine profiles of conditioned media from MCF7, MCF7 induced to undergo EMT by treatment of TGF-β, TNF-α and prolonged mammosphere culture, and MDA-MB-231 cells were analyzed by RayBio® Human Cytokine Antibody Array V.
Project description:The goal of the experiment was to demonstrate if the overexpression of human-Prune-1 in Triple Negative breast cancer cells induces M2-polarization of macrophages in vitro. For this purpose, murine primary cells from breast tumor developed by Genetically Engineered Mouse Models (GEMMs) of TNBC (i.e., MMTV-Wnt1) and metastatic TNBC overexpressing both human Prune-1 and Wnt1 in mammary gland (i.e., MMTV-Prune-1/Wnt1) were obtained. Conditioned media were collected from these primary cells (1x106 cells) after 24 hours. Murine macrophages (J774A.1 and Raw264.7; 1x106) were starved for six hours and then grown for 48 hours in those conditioned media collected from MMTV-Wnt1 and MMTV-Prune-1/Wnt1 cells. Untreated macrophages were used as negative control for the experiment.
