  1. 1. Leukocytes in Angiogenesis : Learning from Transplanted Pancreatic Islets

    Author : Gustaf Christoffersson; Mia Phillipson; Kristian Pietras; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; pancreatic islet transplantation; islets of Langerhans; diabetes mellitus; leukocytes; neutrophils; macrophages; pericytes; MMP-9; VEGF-A; Medical Science; Medicinsk vetenskap;

    Abstract : Angiogenesis, the growth of new blood vessels, is a complex process involving several cell types and molecular signals. Excessive vascular growth is a problem in tumors, and insufficient vascularization hampers the function of transplanted insulin-producing pancreatic islets. READ MORE

  2. 2. Functional characterization of pro-angiogenic neutrophils

    Author : Jalal Lomei; Mia Phillipson; Gustaf Christoffersson; Johan Kreuger; Lars Olaf Cardell; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; leukocytes; neutrophils; pro-angiogenic neutrophils; islets transplantation; intravital microscopy; aortic ring assay; phagocytosis; ROS production; hypoxia; vascular permeability; neutrophil recruitment; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : The vascular system stretches throughout the body to provide oxygen, nutrition, and to remove waste products from cell metabolism. Angiogenesis, formation of new blood vessels by sprouting from pre-existing vessels, is one of the main mechanisms involved in blood vessel formation. READ MORE

  3. 3. Macrophages and neutrophils in tissue homeostasis and recovery from ischemic injury

    Author : Kristel Parv; Mia Phillipson; Gustaf Christoffersson; Per-Ola Carlsson; Stephen Jenkins; Uppsala universitet; []
