1. 11. Angiogenesis in childhood malignancies

   Författare :Erik Sköldenberg; Rolf Christofferson; Göran Läckgren; Agneta Nordenskjöld; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Angiogenesis Factor; Biopsy; Needle; Neovascularization; Pathologic; Nephroblastoma; Reference value; Kirurgi; Surgery; Kirurgi; Pediatric Surgery; kirurgi; särskilt barnkirurgi;

   Sammanfattning : Angiogenesis is necessary for the growth and spread of solid tumors. In these studies angiogenesis was measured in childhood malignancies in general and in Wilms’ tumor in particular, and cutting needle biopsy (CNB) specimens were evaluated for diagnosis in childhood renal tumors.

3. 12. Vascular endothelial growth factor receptors in angiogenesis

   Författare :Kui Huang; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; endothelial cells; VEGF receptor; signal transduction; pertide; angiogenesis; Genetik; Clinical genetics; Klinisk genetik; Medical Biochemistry; medicinsk biokemi;

   Sammanfattning : Angiogenesis is a process in which new capillaries sprout from preexisting blood vessels. Vascular endothelial growth factor (VEGF) promotes endothelial cell proliferation and migration and thereby stimulates angiogenesis. VEGF receptors (VEGFRs) have been implicated as key regulatory components in endothelial cells. LÄS MER

4. 13. On angiogenesis modulation

   Författare :Mattias Kalén; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : During evolution, the transition from unicellular to multicellular organisms required the origin of a transport system capable of interconnecting specialized cells throughout the body of the organism. In higher animals, this route of transportation is the cardiovascular system, which allows gas exchange, and transport of immune cells, hormones, macromolecules, nutrients and waste products.

5. 14. Cellular and molecular roles for CDC42 in angiogenesis

   Författare :Marco Castro; Christer Betsholtz; Bàrbara Laviña; Rui Benedito; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CDC42; angiogenesis; endothelial cell; vascular malformation; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

   Sammanfattning : Angiogenesis is the physiological process by which new blood vessels grow and critically depends on the interplay between the major vascular units: endothelial cells, pericytes and smooth muscle cells. Dysfunction and mispatterning of blood vessels are associated with the progression of many vascular complications, and therefore, understanding the causes of vascular dysmorphia is a central question in vascular biology.

7. 15. 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
