Project description:RNAseq of CD4 cells from 83 individuals with musculoskeletal complains (age 51y, range 19-86. male 22%) were collected at the Rheumatology Clinic during 2022-2023 . Cells were activated with anti-CD3 for 48 hours.
Project description:Human bone-marrow-derived mesenchymal stem cells from young and old donors and tenogenic, chondrogenic and osteogenic constructs derived from these were subject to RNASeq and miRNASeq. We wished to identify common pathways of musculoskeletal ageing.

Project description:Bone regeneration is a highly efficient process allowing scarless healing after injury. Yet, musculoskeletal traumatic injury, when fracture is combined with adjacent muscle injury, alters bone healing leading to fibrous nonunion. The periosteum, the outer layer of bones, is a critical source of skeletal stem/progenitor cells (SSPCs), as well as immune, endothelial and neural cells during bone repair. We generated single nuclei datasets from the injured perioteum and hematoma at day 1-post fracture and from the hematoma/callus at day 5 post-musculoskeletal traumatic injury. These datasets were analyzed in combination with datasets from GSE234451.
Project description:Innate lymphoid cell (ILC) subsets that mirror helper T cells in their effector cytokine profiles have recently emerged as central players in both homeostatic and inflammatory conditions. Like their Th1, Th2 and Th17/Th22 helper T cell counterparts, ILC subsets are categorized based on their expression of specific transcription factors and effector cytokines: group 1 ILC (ILC1) express T-bet and IFN-γ; group 2 ILC (ILC2) express GATA-3 and type 2 effector cytokines such as IL-13 and IL-5; and group 3 ILC (ILC3) express RORgt and the cytokines IL-22 and/or IL-17. Under this nomenclature, natural killer (NK) cells and lymphoid tissue inducers (LTi) are considered ILC1 and ILC3, respectively. ILC1 contain both CD4+ and CD4- populations, but whether this phenotypic characteristic reflects functional differences between these two populations is unknown. These studies examine the gene expression profiles of CD4+ vs CD4- ILC1 in a cohort of healthy control subjects. ILC subsets were isolated from the peripheral blood of healthy control subjects. cDNA was isolated and amplified from sorted populations, and gene expression was analyzed by RNAseq
