  1. 1. Regulation of fibroblast activity by keratinocytes, TGF-β and IL-1α : studies in two- and three dimensional in vitro models

    Författare :Anita Koskela von Sydow; Mikael Ivarsson; Torbjörn Bengtsson; Hans Törmä; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fibroblast; Keratinocyte; TGF-β; IL-1α; coculture; fibrosis CTGF CNN 2; dermal; organotypic culture;

    Sammanfattning : Dysregulated wound healing is commonly associated with excessive fibrosis. Connective tissue growth factor (CTGF/CCN2) is characteristically overexpressed in fibrotic diseases and stimulated by transforming growth factor-β (TGF-β) in dermal fibroblasts. Reepithelialisation and epidermal wound coverage counteract excessive scar formation. LÄS MER

  3. 2. Epidermal keratinocytes studied by X-ray microanalysis, with special reference to contact dermatitis : In vivo and in vitro studies of functional changes in human cells

    Författare :Anders Grängsjö; Uppsala universitet; []
    Nyckelord :Medical sciences; X-ray microanalysis; elements; epidermis; keratinocytes; proliferation; cell membrane damage; Ki67; irritants; intracellular elemental content; keratinocyte culture; HaCaT; NHEK; RT-PCR; immunohistochemistry; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; anatomi; Human Anatomy;

    Sammanfattning : By determining the intracellular elemental content, information can be obtained on the physiological status of cells. The cellular content of sodium, magnesium, phosphorus, sulfur, chloride, potassium and calcium can be indicative for proliferation, cell membrane damage or cell death. LÄS MER

  4. 3. Disease-causing Keratin Mutations and Cytoskeletal Dysfunction in Human Skin : In vitro Models and new Pharmacologic Strategies for Treating Epidermolytic Genodermatoses

    Sammanfattning : Epidermolysis bullosa simplex (EBS) and epidermolytic ichthyosis (EI) are rare skin fragility diseases characterized by intra-epidermal blistering due to autosomal dominant-negative mutations in basal (KRT5 or KRT14) and suprabasal (KRT1 or KRT10) keratin genes,  respectively. Despite vast knowledge in the disease pathogenesis, the pathomechanisms are not fully understood, and no effective remedies exist. LÄS MER

  5. 4. Characterisation of human fetal mesenchymal stem cells

    Författare :Cecilia Götherström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Mesenchymal stem cells; fetal stem cell transplantation; intrauterine transplantation; osteogenesis imperfecta; mixed lymphocyte culture; gene array;

    Sammanfattning : Mesenchymal stem cells (MSCs) are present in various tissues of fetal and adult origin. I isolated and expanded MSCs from human fetal 1st trimester livers and observed that they have a shorter cell doubling time compared to adult bone marrow-derived MSCs. LÄS MER

  7. 5. Keratinocytes and Adipose-derived mesenchymal stem cells : The heir and the spare to regenerative cellular therapies for difficult-to-heal skin wounds

    Författare :Hady Shahin; Ahmed Taher Elserafy; Moustafa Elmasry; Folke Sjöberg; Ingrid Steinvall; Daniel Nowinski; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Keratinocytes; ATMP; Bio-production; Adipose-derived mesenchymal stem cells; Wound healing;

    Sammanfattning : Cell-based therapy is considered as Advanced Therapy Medicinal Product, (ATMP), which had increasingly stricter regulations in the last decade. The cells must be produced according to the ‘Guidelines on Good Manufacturing Practice (GMP) specific to Advanced Therapy Medicinal Products’, adopted by the European Medicines Agency (EMA). LÄS MER
