Project description:Comparison between extracellular vesicles produced from 2D-cultured human Mesenchymal Stem Cells (hMSC) in starvation, and extracellular vesicles produced from spheroids of hMSC hydrodynamically stimulated in a cross-slot millifluidic chip.
Project description:An equivalent dosage of human umbilical cord-derived mesenchymal stem cell (HucMSC), adipose tissue-derived mesenchymal stem cell (ADSC), and SVF was orthotopically administered into a cyclophosphamide (CTX)-induced premature ovarian insufficiency (POI) mouse model. The therapeutic impacts were meticulously evaluated employing a suite of assays. The underlying mechanisms were investigated through RNA sequencing (RNA-seq) and mass spectrometry, offering insights into the cellular and molecular responses.
Project description:A microarray study using human Mesenchymal Stem cell line (hMSC-TERTs), was designed in order to detect the differences in global gene expression during proliferation, quiescence (G0) and reactivation post quiescence for 1 hr (R1), 3 hrs (R3) and 24 hrs (R24). Proliferating and re-activated cells were harvested at 70-75% confluency. To induce quiescence, MSCs were cultured in suspension in methyl cellulose in presence of full serum complement. The raw data from gene arrays were normalized and the five samples were compared to each other in order to detect differences in gene expression between the samples.
Project description:The long non-coding RNA Malat1 has been implicated in several human cancers, while the mechanism of action is not completely understood. As RNAs in cells function in the context of RBPs identification of their RNA-binding proteins can shed light on their functionality. We here performed quantitative interactomics of 14 non-overlapping fragments covering the full length of Malat1 to identify possible nuclear interacting proteins. Overall, we identified 35 candidates including 14 already known binders, which are able to interact with Malat1 in the nucleus. Furthermore, the use of fragments along the full-length RNA allowed us to reveal two hotspots for protein binding, one in the 5’-region and one in the 3’-region of Malat1. Our results provide confirmation on previous RNA-protein interaction studies and suggest new candidates for functional investigations.
Project description:We report isoCirc, a long-read sequencing strategy coupled with an integrated computational pipeline to characterize full-length circular RNA (circRNA isoforms) using rolling circle amplification (RCA) followed by long-read sequencing. Applying isoCirc to 12 human tissues, we determined full-length structures and examined tissue specificities of circRNA isoforms in human transcriptomes.
