Project description:Skeletal muscle possesses the ability to adapt its size in response to milieus, which is called plasticity. Overload like resistance training induces the increment of muscle mass called muscle hypertrophy. Muscle stem cells (also known as muscle stem cells) function to supply new nuclei for myofiber during the overload in muscle. Using compensatory hypertrophy in plantaris muscles, we isolated MuSCs from plantaris muscles 4 days after surgery. Control MuSCs were also prepared from sham plantaris muscles.
Project description:We treated 6 week-old KPC mice with vehicle or CA-4948 and perform scRNASeq to assess transcriptomic changes in CAFs and immune cells
Project description:GPCRs have emerged as crucial regulators of muscle stem cell (MuSC) quiescence, yet the specific repertoire of GPCRs in quiescent MuSCs and the underlying regulatory network remain largely elusive. By employing pharmacological and inducible-genetic methods, we have identified two niche-derived GPCR ligands, endothelin-3 (ET-3) and neurotensin (NT), which bind to EDNRB and NTSR2 receptors, respectively, reinforcing the maintenance of MuSC quiescence. To comprehensively unravel the molecular mechanisms underlying the inhibitory effects of ET-3 and NT on MuSC activation, we conducted RNA sequencing (RNA-seq) analysis on FACS-purified MuSCs that underwent a 5-day in vitro treatment with ET-3 or NT
Project description:scRNAseq of HPMCs isolated ex vivo from 3 Patients. Targeted scRNASeq was applied using BD onco Panel with a additional genes. Purpose of the experiment was to characterize HPMC phenotype ex vivo and compare with the phenotype observed in RNAseq of HPMCs treated with IL17A and TNF.
