Project description:We injected LLC1 cells into tibia to construct a murine model to study bone microenvironment in cancer bone metastasis. We used single cell RNA sequencing (scRNA-seq) to analyze the cellular heterogeneity of tumor-infiltrating cells.
Project description:Single-cell RNA-sequencing of osteocyte-derived mitochondria recipient cells in the intra-tibial injection of LLC1 cells murine model.
Project description:LLC1 cells were injected into the tibia of DMP1-Cre PhAM mice to study the intercellular mitochondrial transfer in the bone microenvironment. We used single-cell RNA sequencing (scRNA-seq) to analyze the cellular heterogeneity of osteocyte-derived mitochondria recipient cells.
Project description:Description of cellular and molecular landscape of vitreal immune cells following optic nerve crush injury plus intra-ocular injection of particulate β-glucan after 3days, in WT and Itgam-/- mice
Project description:Development of a vaccine formula that alters the tumour-infiltrating lymphocytes to be more immune active against a tumour is key to the improvement of clinical responses to immunotherapy. Here, we demonstrate that, in conjunction with E7 antigen specific immunotherapy, and IL-10 and PD-1 blockade, intra-tumoral administration of caerin 1.1 and 1.9 peptides further improves the tumour microenvironment (TME) when compared with injection of a control peptide. We used single cell transcriptomics and mass spectrometry-based proteomics to quantify changes in cellular activity across different cell types within the TME. We show that the injection of caerin 1.1/1.9 increases immune activating macrophages and NK cells, while reducing immunosuppressive macrophages with M2 phenotype, and increased numbers of activated CD8+ T cells with higher populations of memory and effector-memory CD8+ T subsets. Proteomic profiling demonstrated activation of Stat1 modulated apoptosis and production of nitric oxide. Further, computational integration of the proteome with the single cell transcriptome was consistent with deactivation of immune suppressive B cell function following caerin 1.1 and 1.9 treatment.
Project description:Primary human skeletal muscle cells (Lonza) were treated with LLC1 conditioned medium, LLC1 conditioned medium plus Calcitriol, LLC1 non-conditioned medium or LLC1 non-conditioned medium plus Calcitriol for a period of 24 hours prior to isolation of RNA.
Project description:This study aimed to determine whether alignment correction by high tibial osteotomy can change the biological intra-articular microenvironment of osteoarthritic knees.
