1. 1. Next generation molecular diagnostics using ultrasensitive sequencing

   Författare :Stefan Filges; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Liquid biopsy; cell-free DNA; circulating tumor DNA; molecular diagnostics; next-generation sequencing; unique molecular identifiers; melanoma;

   Sammanfattning : Massively parallel sequencing enables the exploration of the genetic heterogeneity within microbial, viral and tumor cell populations. Detecting circulating tumor DNA in blood and other body fluids has the potential to revolutionize molecular diagnostics. LÄS MER

3. 2. Preservation of fertility through cryopreservation and in vitro maturation of human ovarian follicles and oocytes

   Författare :Julius Hreinsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Oocyte; maturation in-vitro; cryopreservation; ovarian follicles; culture; IVM; preservation of fertility;

   Sammanfattning : One of the most rapidly expanding fields in assisted reproduction is the preservation of fertility for young women at risk of premature ovarian failure. This may be caused by cytotoxic therapy or other reasons. Cryopreservation of follicles in ovarian tissue has been successful in animal models with live young being born. LÄS MER

4. 3. 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

5. 4. Studies on the interaction of human cells with transplantable materials for skin repair and cardiovascular surgery

   Författare :Katarina Jansson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Cell culture; Keratinocytes; Fibroblasts; Endothelial cells; Reepithelialization; In vitro endothelialization; Tissue engineering; Biomaterial: Dermal substitute; Synthetic vascular graft; Heart valve bioprosthesis;

   Sammanfattning : Tissue engineering is becoming an important field for the development of new tissues in vitro for replacement of diseased or worn out parts of the body. This thesis describes some characteristics of cultured human cells seeded on transplantable materials for skin repair and cardiovascular surgery. LÄS MER

7. 5. Development of superselective endovascular tissue access and sampling

   Författare :Rikard Grankvist; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Endovascular techniques have revolutionized healthcare by allowing effective treatments of vascular diseases not possible through other surgical means. They have also largely supplanted some surgical treatments due to increased safety and equal or sometimes increased efficacy. LÄS MER
