Expression data from clone sorted tumor endothelial subsets

Project description:Competitive interactions between emerging blood vessels determine the clonogenic contribution to developing vascualture. Using a multi-color cre reporter, CD31+CD45-VeCad+ clones were isolated and analyzed for expression differences. Tamoxifen labeled CD31+, CD45-VeCad+ tumor endothelial cells were isolated by FACS for analysis from separate tumors. The most frequent clone was compared to the least frequent clone between and across tumors. The strain of mice is C57BL/6.

Vessel Forming Mesenchymal Stromal Cell Populations

Project description:We have identified two vessel forming mesenchymal stromal cell populations. Population 1 (P1) is CD45-Ter119-Tie2+PDGFRa-CD31+CD105highSca1low and gives rise to stunted vessels (incomplete tubular structures) in a transplant setting, and Population 2 (P2) which is CD45-Ter119-Tie2+PDGFRa+CD31-CD105lowSca1high and forms stunted vessels and fat. To test the homogeneity and signal interactions of these populations we performed 10X single cell RNA-sequencing on them.

Expression data from endothelial SP and MP cells

Project description:We identified an endothelial progenitor/stem like population in the endothelial fraction of preexsiting blood vessels. And we used microarray to see the difference of gene expression profiles between these two populations. Hindlimb muscle of wild type C57BL/6 were digested to single cells and stained with anti-CD31 antibody, anti- CD45 antibody, Propidium iodide and hoechst 33342. CD31+CD45- side population cells and CD31+CD45- main population cells were sorted by flow cytometry for RNA extraction and hybridized on Affimetrix microarrays.

Gene expression profile of HoxA9 over expressing and empty vector (EV) control Hemato-Endothelial Progenitors (HEPs) subpopulations

Project description:During hematopoietic differentiation of hESCs, HOXA9 expression parallels hematopoietic development but is restricted to the hemogenic precursors (HEP, CD31+CD34+CD45-), and diminishes as HEPs differentiate into blood cells (CD45+). Enforced expression of Hoxa9 in hESCs robustly promoted differentiation into primitive (CD34+CD45+) and total (CD45+) blood cells with higher clonogenic (CFU) potential. To identify patterns of gene expression that could explain at the molecular level the developmental impact of HOXA9 in hematopoietic commitment of hESCs, we performed gene expression profile in FACS-purified EV- and HOXA9-HEPs.

Gene expression profiles of normal human tonsillar cell subpopulations FACS sorted based on expression of cell surface markers

Project description:To characterize the progenitor-enriched CD44+NGFR+ cells present in the crypt and surface regions of the tonsil, we used an Illumina array system to analyze the transcriptome of these cells isolated from the tonsillar crypt and surface regions of three different individuals as well as the total epithelial (CD45-CD31-) populations obtained from two of these. To enrich for epithelial progeniors in human palatine tonsil tissue, hematopoietic and endothelial cells were depleted from freshly isolated cell suspensions derived from palatine tonsils using fluorescence-activated cell sorting (FACS). The resultant CD45-CD31- population was further fractionated into four subpopulations using antibodies against CD44 and NGFR. Based on the immunohistochemical phenotype and in vitro functional assays, CD44+NGFR+ subpopulations were identified as epithelial progenitor-enriched subsets. Microarray profiling was used to derive gene expression signatures of CD45-CD31- subsets (total epithelial-enriched) and CD45-CD31-CD44+NGFR+ subpopulations (progenitor-enriched).

Transcriptome analysis of synovial osteoprogenitor populations in mice with antigen-induced arthritis and non-immunized mice

Project description:The aim of this experiment was to analyze differences in gene expression between potential osteoprogenitor populations in synovial compartment of non-immunized mice and mice with antigen-induced arthritis (AIA). We analyzed transcriptome of TER119–CD31–CD45–CD51+CD200+CD105– cells from nonimmunized mice, TER119–CD31–CD45–CD51+CD200+CD105– cells from mice with arthritis, and TER119–CD31–CD45–CD51+CD200–CD105+ from mice with arthritis. Comparison between nonimmunized and arthritic mice served to determine changes in TER119–CD31–CD45–CD51+CD200+CD105–population induced by arthritis. Comparison of TER119–CD31–CD45–CD51+CD200+CD105– and TER119–CD31–CD45–CD51+CD200–CD105+ from mice with arthritis aimed to define transcriptomic differences between those two populations.

Transcription as a function of tissue environment

Project description:We are interested in whether fibroblasts (CD45-CD31-Epcam-PDPN+PDGFRA+) cells exhibit unique transcriptional profiles. To this end, we digested tissues and FACS sorted CD45-CD31-Epcam-PDPN+PDGFRA+ fibroblasts CD45-CD31-Epcam-PDPN+PDGFRA- mesothelial cells and compared the transcriptional profiles of these cells.

Developmental changes in the in vitro activated regenerative activity of primitive mammary epithelial cells

Project description:Many normal adult tissues contain rare stem cells with extensive self-maintaining regenerative potential. During development, the stem cells of the hematopoietic and neural systems undergo intrinsically specified changes in their self-renewal potential. In the mouse, mammary stem cells with transplantable regenerative activity are first detectable a few days before birth. They share some phenotypic properties with their adult counterparts but are enriched in a subpopulation that displays a distinct gene expression profile. Here we show that fetal mammary epithelial cells have a greater direct and inducible growth potential than their adult counterparts. The latter feature is revealed in a novel culture system that enables large numbers of mammary stem cells with serially transplantable activity as well as in vitro clonogenic progenitors to be produced within 7 days from single fetal or adult input cells. We further show that these responses are highly dependent on novel factors produced by fibroblasts. These findings provide new avenues for elucidating mechanisms that regulate normal mammary epithelial stem cell properties at the single-cell level, how these change during development, and how their perturbation may contribute to transformation. We used microarrays to compare the transcriptome of E18.5 fetal and adult MRU-enriched mammary cells. Three biological replicates each of CD31-CD45-Ter119-BP-1-EpCAM+CD49f+ adult basal cells and CD31-CD45-Ter119-EpCAM++CD49f+ fetal cells were sorted. RNA was extracted and hybridized to the Agilent One-Color Gene Expression Arrays .
