    Sammanfattning : Infertility affects 15% of reproductive-aged couples. The milieu surrounding the growing embryo is of outmost importance, and should be optimised during in vitro fertilisation (IVF). Many biological processes, such as angiogenesis, coagulation, and immune processes need to be well regulated for a pregnancy to occur and progress normally. LÄS MER

  3. 2. Developmental disturbances of the embryo in diabetic pregnancy

    Författare :Parri Wentzel; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; diabetes; pregnancy; embryo; malformation; glucose; ROS; SOD; NAC; prosta- glandin; COX; COX inhibitor; gene expression; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : Maternal diabetes during pregnancy constitutes an increased risk for congenital malformation in the offspring. Previous studies have suggested that diabetic embryopathy is associated with an excess of reactive oxygen species (ROS) as well as with a disturbance of prostaglandin (PG) metabolism. LÄS MER

  4. 3. Optimisation of human embryonic stem cell derivation and culture : towards clinical quality

    Författare :Susanne Ström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :hESC;

    Sammanfattning : For clinical grade human embryonic stem cell (hESC) lines, a robust derivation and culture system without any substances having animal origin would be optimal. The general aims of these studies have been to gradually improve our hESC derivation and cultures. LÄS MER

  5. 4. Hypoxia and Stem Cells in Normal and Tumor Development

    Författare :Camilla Niklasson; Avdelningen för translationell cancerforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; neuroblastoma; hypoxia; preclinical cancer models; ALDH; HIF-2α; PT2385;

    Sammanfattning : Neuroblastoma is a childhood malignancy of the sympathetic nervous system and accounts for 15% of all cancer-related deaths in children. To understand the biology behind neuroblastoma, clarify timing of cellular events and expression profiles of proteins preceding neuroblastoma initiation, we need more relevant preclinical models.

  7. 5. Nitrogen uptake and assimilation during Norway spruce somatic embryogenesis : investigating the role of glutamine

    Författare :Johanna Carlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Sweden is currently experiencing shortage of Norway spruce (Picea abies) seeds due to e.g. irregular flowering and the recent year’s outbreaks of pests and pathogens destroying cones and seeds. LÄS MER
