  1. 1. VEGFR-2 in Endothelial Differentiation and Vascular Organization

    Författare :Dan Edholm; Lena Claesson-Welsh; Xiujuan Li; Victoria Bautch; Uppsala universitet; []
    Nyckelord :Molecular medicine; Embryonic stem; VEGFR-2; Flk1; KDR; VEGF; vasculogenesis; angiogenesis; embryoid body; Molekylärmedicin;

    Sammanfattning : The cardiovascular system is the first functional organ to develop during embryogenesis. As the embryo reaches above a certain size, passive diffusion of gases and nutrients is no longer compatible with efficient growth. LÄS MER

  2. 2. Hypoxia-inducible factors (HIFs) and biological responses, in hypoxia, inflammation and embryonic vascular development

    Författare :Maria Hägg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Embryonic stem cell; embryoid body; HIF-1a; hypoxia; VEGF; angiogenesis; vasculogenesis; peritoneal dialysis;

    Sammanfattning : ABSTRACT Low oxygen tension (hypoxia) is a major inducer of neovascularisation and evidence emerging has indicated that oxygen tension and hypoxia-inducible factors (HIFs), a family of oxygen-regulated heterodimeric transcription factors, may play important roles in vascular and hematopoietic development. This thesis has focused on studying molecular and cellular mechanisms, by which cells and organisms sense changes in oxygen tension, and how this signal is transduced by HIFs into downstream signalling.

  3. 3. Modulation of Angiogenesis by Laminins and Heparan Sulfate

    Författare :Lars Jakobsson; Lena Claesson-Welsh; Johan Kreuger; Elisabetta Dejana; Uppsala universitet; []
    Nyckelord :Molecular medicine; Embryonic stem; heparan sulfate; laminin; basement membrane; VEGFR-2; VEGF; endothelial cell; signaling; angiogenesis; vasculogenesis; embryoid body; Molekylärmedicin;

    Sammanfattning : Blood vessels transport blood with essential nutrients and oxygen to the cells in our body. In a healthy adult, formation of new vessels (angiogenesis) occurs only in case of tissue repair and growth. LÄS MER

  4. 4. 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

  5. 5. Studies of the vascular endothelial growth factors, VEGFs, and their receptors, focusing on VEGF-B

    Författare :Birgitta Olofsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; vasculogenesis; angiogenesis; VEGF; VEGF-B; VEGF receptors; neuropilin;

    Sammanfattning : The inner lining of all blood- and lymphatic vessels are composed of endothelial cells. Their growth and differentiation are in part regulated by polypeptide growth factors and their receptors. LÄS MER
