  1. 16. Recreating the microenvironment of the neurovascular unit

    Författare :Isabelle Matthiesen; Anna Herland; Thomas E. Winkler; Stéphanie Descroix; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microphysiological systems; neurovascular unit; induced pluripotent stem cells; extracellular matrix; hydrogels; in vitro models; mikrofysiologiska system; neurovaskulära enheten; inducerade pluripotenta stamceller; extracellulära matrisen; hydrogeler; in vitro modeller; Bioteknologi; Biotechnology;

    Sammanfattning : The neurovascular unit (NVU) comprises the blood-brain-barrier (BBB) and its surrounding astrocytes, pericytes and neurons that are embedded in the extracellular matrix (ECM). As the main function of the BBB is to protect the brain from inlet of pathogens and toxins, the specialized endothelial cells that keep the barrier tight will also hinder the passage of pharmaceuticals.

  3. 17. Structural design and properties of hydrogel biomaterials

    Författare :Mikael Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Polyacrylic acid; Mechanical properties; Microfibrillated cellulose; Drug release; Chitosan; Biomaterials; Swelling; Hydrogels;

    Sammanfattning : Today a range of materials are used in medical applications; such materials are collectively denoted as biomaterials. A special class of biomaterials currently given much scientific interest is hydrogels. In particular a contemporary research topic is to create multicomponent materials in which synergetic effects are achieved. LÄS MER
