Project description:Mesenchymal stem cells (MSCs) have been isolated from various organs and extensively studied for their potential in regulating transplantation. MSCs from different mammalian species are well characterized; however, the properties and therapeutic potential of porcine bone marrow-derived MSCs (BM-MSCs) remain unclear. In this study, we aimed to profile the characteristics of porcine BM-MSCs by comparing their gene expression patterns and immunomodulatory properties with those of porcine peripheral blood mononuclear cells (PBMCs) and bone marrow-attached cells (BMACs). Using quantitative polymerase chain reaction, flow cytometry, immunocytochemistry, and RNA sequencing, we confirmed the expression of key MSC markers, including CD105, CD73, and CD90, in porcine BM-MSCs, and aligned them closely with human MSCs. We found significant differences in gene expression between BM-MSCs and PBMCs, with BM-MSCs exhibiting a distinct expression pattern similar to that of BMACs. Gene ontology enrichment analysis revealed the pathways involved in immune modulation and tissue repair, underscoring the potential of BM-MSCs to enhance immune regulation. Notably, BM-MSCs exhibited higher transforming growth factor-beta levels than PBMCs, suggesting a central role in their immunosuppressive function. These findings indicate the immunomodulatory capabilities of porcine BM-MSCs and support their application in xenotransplantation, where they may help mitigate graft rejection and promote tissue regeneration.
Project description:With this experiment, we aimed at showing changes in the proteome and secretome of porcine peripheral blood mononuclear cells (PBMC) after stimulation with Banana Lectin (BanLec).
Project description:Primary human peripheral blood mononuclear cells were isolated from full blood by standard ficoll centrifugation. Cells were washed and processed immediately.
Project description:In vivo microarray study of global gene expression changes in peripheral blood mononuclear cells (PBMCs) of German Landrace pigs during the innate immune response to porcine reproductive and respiratory syndrome virus vaccination.
Project description:Ankylosing spondylitis (AS) is an inflammatory arthritis of the axial skeleton that predominantly affects young men. HLA-B27 has remained the major genetic risk factor in AS. Recently, more non-MHC genes has been discoverd to be involved in AS pathogenesis, especially IL-23 signalling pathway related genes. We performed a proteomic study of the peripheral blood mononuclear cells from AS patients and healthy donors.
Project description:We collected peripheral blood from leukemia patients at different stages, including those newly diagnosed as untreated, as well as those in remission on therapy, with a subset of samples including peripheral blood and bone marrow samples. First, mononuclear cells were isolated from the collected peripheral blood, followed by single-cell RNA sequencing and follow-up sequencing results for subgroup classification, focusing on changes such as glycolipid metabolism of B cells as well as T cells. The aim of this project was to explore the changes in metabolic remodeling in leukemia patients with the aid of single-cell technology to provide assistance in the diagnosis and treatment of the disease.
