Bulk RNA-seq of human adipose-derived CD73-positive cells and heterogeneous mesenchymal stem/stromal cells

Project description:To characterize the transplantation efficacy of CD73+ cells in a mouse model of colitis, we established CD73+ cells isolated from human adipose tissue and the conventional heterogeneous cell populations (from now on referred to as cMSCs) attached to the culture dish. We then performed a comparative transcriptome analysis between CD73+ cells and cMSCs derived from three individuals.

Expression data from CD73 positive adipose derived mesenchymal stem cells (CD73+ AD-MSCs) and CD73 negative adipose derived mesenchymal stem cells (CD73- AD-MSCs) of mouse

Project description:MSCs are a heterogeneous population and the specific population of MSCs may exhibit a selective ability for tissue repair. The aim of our research was to adapt the CD73+ subgroup of adipose derived MSCs (AD-MSCs) for the therapy of myocardial infarction (MI). Our results revealed that CD73+ AD-MSCs played more effective role in the acceleration function of cardiac recovery by promoting angiogenesis in a rat model of MI compared to mixed AD-MSCs and CD73- AD-MSCs. Microarray analysis shows differences between CD73+ and CD73- AD-MSCs when transcription profile of these two subgroups were compared, especially in VEGF pathway.

CD73 Immune Checkpoint Defines Inducible Regulatory NK cells in the Tumor Microenvironment

Project description:High levels of ecto-5'-nucleotidase (CD73) have been implicated in immune suppression and tumor progression. Elevated levels of CD73 has also been observed in patients who progress on anti–PD-1 immunotherapy. While regulatory T cells can express CD73 and inhibit T cell responses via the production of adenosine, less is known if conventional T cells and natural killer (NK) cells can express CD73. We found that the expression of CD73 is restricted to tumor-infiltrating NK cells and the frequency of these cells correlate with larger tumor size in patients with breast cancer. In addition, the expression of other immune checkpoint receptors including LAG-3 and VISTA was significantly higher in CD73 positive NK cells than on CD73 negative NK cells. Furthermore, the prognostic value of CD73 gene expression was influenced by NK cell signature expressed in patients with breast cancer and sarcoma. Mechanistically, upon engagement of 4-1BBL on tumor cells, NK cells transport CD73 in intracellular vesicles to the cell surface and extracellular space via actin polymerization-dependent exocytosis. These CD73 positive NK cells undergo transcriptional reprogramming and upregulate IL10 production via STAT3 transcriptional activity and suppress CD4 T cell activity. Altogether, our results support that tumors can hijack NK cells as a means to escape immunity and that CD73 expression defines an inducible population of NK cells with immune regulatory properties within the tumor microenvironment.

miRNA expression data from CD73-positive Rods, MÃ¼ler glia and E 17.5 Retinal Progenitors

Project description:During retinal development, progenitor cells give rise to six different types of neurons, and one glial cell. This process requires the expression of genes that confer specific functions and identity to each cell. Previous works have reported the miRNAs expression profile in retina, but is still necessary to further define individual retinal cell populations profiles. We isolated postmitotic mice CD73-positive Rods, MÃ¼ller glial cells and Retinal Progenitors Cells (E17.5); we then analyzed their miRNA profile expression by microarrays. Using wild type mice we FACS-isolated postmitotic CD73-positive Rods (posnatal day 5). We isolated primary MÃ¼ller glia cultures from postnatal day 8 mice and retinal progenitors cells from E17.5 mouse embryos; we then sent the samples to the gene expression unit at Instituto de Medicina Genomica (INMEGEN), to analyze their miRNA profile expression by microarrays.

Single-cell protein-expression map of bone marrow reveals stromal cell subset selection with stress

Project description:We identified CD73+ bone marrow stromal cells as hematopoietic niche candidates. To further validate our finding, we tested the functional role of CD73 during bone marrow transplantation using CD73-/- mice. We evaluated the transcriptome of transplanted WT hematopoietic stem and progenitor cells from WT or CD73-/- recipient mice and found changes in metabolic, cell cycle and signaling genes.

CD73 knockdown effect in pancreatic cancer cell lines

Project description:Recent studies have shown that non-enzymatic function of CD73 play a key role in tumor progression, but this function of CD73 in pancreatic cancer cells has not been studied. In the present study, PANC-1 cell lines were transfected with CD73 siRNA, and proliferation ability and cell cycle was significantly inhibited. However, little is known about the mechanisms involved in CD73 regulation in tumors.
