  1. 16. Epigenetic Control of Mammalian Development : Studies on an imprinting control region

    Författare :Liang Liu; Pärt Peterson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Epigenetic; Genomic imprinting; DNA methylation; Igf2; H19; Insulator; CTCF; Imprinting control region; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; zoologisk utvecklingsbiologi; Animal Development;

    Sammanfattning : A subset of autosomal genes is preferentially or exclusively expressed from one of the parental alleles. This phenomenon, termed genomic imprinting, is highlighted by the neighboring Igf2 and H19 genes, which are monoallelically expressed on opposite parental chromosomes. These features are governed by a 2. LÄS MER

  3. 17. Molecular specification of expanded forebrain neural stem and progenitor cells

    Författare :Malin Parmar; Neurobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; teratology; ontogeny; embryology human ; Development biology; developmental control genes; in vitro expansion; transplantation; precursor cell; stem cells; progenitor cell; human; mouse; Utvecklingsbiologi; teratologi; embryologi människa ;

    Sammanfattning : The molecular specification of neural precursor cells has been suggested to be a progressive process, with a transition from an early requirement for extrinsic signals to intrinsic mechanisms. Thus, the cells in the nervous system acquire distinct fates in response to extrinsic signals, which activate repertoires of transcription factors in a region and cell type specific manner. LÄS MER

  4. 18. The role of PDGF-A in lung development, injury and repair

    Författare :Leonor Gouveia; Johanna Andrae; Christer Betsholtz; Brigid Hogan; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lung; organogenesis; PDGF; signalling pathway; development;

    Sammanfattning : The developmental processes that take place during embryogenesis depend on a great number of proteins that are important for cell-to-cell communication. Platelet-derived growth factors are known to be important for epithelial-mesenchymal interactions during development and organogenesis. LÄS MER

  5. 19. The Role of the SHB Adapter Protein in Cell Differentiation and Development

    Författare :Vitezslav Kriz; Michael Welsh; Urban Lendahl; Uppsala universitet; []
    Nyckelord :Cell biology; SHB; transgene; ES cells; cavitation; knockout; mouse; vasculogenesis; hematopoiesis; endoderm; mesoderm; malformation; Cellbiologi;

    Sammanfattning : The present study was conducted in order to assess a role of the SH2 domain-containing adapter protein SHB in development and cell differentiation.Embryonic stem (ES) cells overexpressing SHB and SHB with an inactive SH2 domain (R522K-SHB) were obtained. LÄS MER

  7. 20. A-to-I RNA editing : Function and consequences during brain development

    Författare :Ylva Ekdahl; Marie Öhman; Kazuko Nishikura; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RNA editing; miRNAs; Brain development; Molecular Biology; molekylärbiologi;

    Sammanfattning : The aim of my thesis has been to study how A-to-I RNA editing of miRNAs is regulated during brain development and the biological function of these editing events.Using high throughput RNA sequencing, we performed an unbiased search for edited, mature miRNAs in total mouse brain tissue from three developmental stages.
