  6. 4. Keratinocytes in tissue engineering of human skin: invitro and in vivo studies

    Author : Camilla Fredriksson; Gunnar Kratz; Fredrik Huss; Xiao-Feng Sun; Bengt Gerdin; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Keratinocytes tissue engineering; Plastic surgery; Plastikkirurgi;

    Abstract : Full thickness wounds, such as deep burns, need restoration of both the dermal and epidermal layers of the skin. In normal wound healing, re-epithelialization occurs by migration and proliferation of keratinocytes from the wound edges and by differentiation of stem cells from remaining hair follicles.

  7. 5. Depth Profiling of the Passive Layer on Stainless Steel using Photoelectron Spectroscopy

    Author : Wendy Fredriksson; Kristina Edström; Fredrik Björefors; Sannakaisa Virtanen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; depth profile; stainless steel; passive film; XPS; HAXPES; corrosion; powder metallurgical; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : The physical properties of the protective passive films formed on the surface of stainless steels under electrochemical polarization in different electrolytes were studied. The structure of these films was analyzed as a function of depth using photoelectron spectroscopy (PES). READ MORE
