Expression profiling of fetal mammary cells

ABSTRACT: We use RNA-sequencing to generate gene expression profiles of fetal mammary cells with unique sorting strategies. These analyses reveal that sorting fetal mammary cells with Sox10 and EpCAM sorting markers provides a stroma-free fMaSC-enriched cell population. The gene expression profiling of these cells offers a resources to probe the molecular mechanisms that specify this unique cell state.

Expression profiling of fetal mammary cells that express ectopic levels of Sox10

Project description:We use RNA-sequencing to generate gene expression profiles of fetal mammary cells that have been induced to overexpress Sox10. These data highlight multiple important molecular mechanisms that are altered in response to this perturbation, and offer a resource to probe the basis of the stem/progenitor and EMT-like functions that are mediated by Sox10 in mammary cells.

Gene expression profiles of normal human mammary cell subpopulations FACS sorted based on expression of CD49f and EpCAM

Project description:To delineate epithelial subpopulations in human mammary tissue, hematopoietic and endothelial cells were depleted from freshly isolated cell suspensions derived from reduction mammoplasties by fluorescence-activated cell sorting. The resultant Lin- population was fractionated into four distinct subpopulations using CD49f (α6-integrin) and epithelial cell adhesion molecule (EpCAM; also referred to as CD326 and ESA). Based on the immunohistochemical phenotype, and in vivo and in vitro functional assays, these subpopulations were identified as fibroblast-enriched stromal (CD49f -EpCAM-), mammary stem cell (MaSC)-enriched (CD49f hiEpCAM-), luminal progenitor (CD49f +EpCAM+), and mature luminal (CD49f –EpCAM+) cell subpopulations. Microarray profiling was used to derive gene expression signatures representative of these subpopulations using freshly sorted cells (>90% purity) from normal breast tissue. The four mammary cell subpopulations were found to have distinct gene expression profiles.

Project description:To delineate epithelial subpopulations in human mammary tissue, hematopoietic and endothelial cells were depleted from freshly isolated cell suspensions derived from reduction mammoplasties by fluorescence-activated cell sorting. The resultant Lin- population was fractionated into four distinct subpopulations using CD49f (Î±6-integrin) and epithelial cell adhesion molecule (EpCAM; also referred to as CD326 and ESA). Based on the immunohistochemical phenotype, and in vivo and in vitro functional assays, these subpopulations were identified as fibroblast-enriched stromal (CD49f -EpCAM-), mammary stem cell (MaSC)-enriched (CD49f hiEpCAM-), luminal progenitor (CD49f +EpCAM+), and mature luminal (CD49f âEpCAM+) cell subpopulations. Microarray profiling was used to derive gene expression signatures representative of these subpopulations using freshly sorted cells (>90% purity) from normal breast tissue. The four mammary cell subpopulations were found to have distinct gene expression profiles. Four mammary cell subpopulations from three individual patient samples were analyzed.

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 .

Mapping the protein interaction network of adaptor protein complex in Arabidopsis identifies P34 as a common stability regulator

Project description:Adaptor protein (AP) complexes are evolutionarily conserved vesicle transport regulators that recruit coat proteins, membrane cargos and coated vesicle accessory proteins. Since in plants endocytic and post-Golgi trafficking intersect at the trans-Golgi network, unique mechanisms for sorting cargos of overlapping vesicular routes are anticipated. The plant AP complexes are part of the sorting machinery, but despite some functional information, their cargoes, accessory proteins, and regulation remain largely unknown. Here, by means of various proteomics approaches, we generated the overall interactome of the five AP and the TPLATE complexes in Arabidopsis thaliana. The interactome converged on a number of hub proteins, including the thus far unknown adaptin binding-like protein, designated P34. P34 interacted with the clathrin-associated AP complexes, controlled their stability and, subsequently, influenced clathrin-mediated endocytosis and various post-Golgi trafficking routes. Altogether, the AP interactome network offers substantial resources for further discoveries of unknown endomembrane trafficking regulators in plant cells.
