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: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: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:Type of Experiment: 1) Profiles of Osteoblast vs. osteocyte in vitro; 2) Profiles of osteoblast low density vs. confluency in vitro; 3) Profiles of osteocyte with gap junction vs. without gap junction. Experimental factors: 1) 2T3 osteoblast cells at low density expressed extensive filopodia, reminiscent of early osteoblast precursors and similar to MLO-Y4 dendritic processes. 2) MLO-Y4 osteocytes at low vs. high density represent the genes that are changed in a highly connected network vs. low connected network. The number of hybridizations performed: Triplicate hybridizations for each status. Keywords = Osteoblast Keywords = Osteocyte
Project description:Mechanical force is a fundamental regulator of bone development and homeostasis. Mechanosensitive osteocytes are the most abundant bone cells that form interconnected dendrites to respond to mechanical stimuli and interact with the bone-forming osteoblasts and the bone-remodeling osteoclasts. However, the molecular mechanisms underlying osteocyte maturation and dendrite formation remain unclear. By generating a Piezo1 "knock-out" osteocyte cell line, we identified a key role of Piezo1-mediated mechanotransduction in osteocyte differentiation. QRT-PCR analysis revealed delayed osteocyte differentiation in the Piezo1 KO cells relative to WT cells. By performing bulk RNA sequencing of WT and Piezo1 KO OCY454 cells at early (D1), intermediate (D14), and late (D28) stages of differentiation allowed for the identification of key signaling pathways in driving normal osteocyte dfiferentiation, as well as those regulated by Piezo1 mechanotransduction.
