Sammanfattning : Neural stem cells are the precursors of neurons, astrocytes and oligodendrocytes. During neural development, the division of stem cells takes place close to the lumen of the neural tube, after which they migrate to their final positions within the central nervous system (CNS).

Sammanfattning : Angiogenesis is the formation of new blood vessels from the pre-existing blood vessels. Blood vessels are composed of endothelial cells and supporting musculature. Angiogenesis is regulated by numerous soluble ligands and by cell-matrix interactions. LÄS MER
3. Den sociala differentieringens retorik och gestaltning : Kritiska perspektiv på funktionalistisk förorts- och bostadsplanering i Stockholm från 1900-talets mitt
Sammanfattning : In this thesis, I analys suburb- and housing planning and interior decoration carried out primarily in Stockholm between the 1930s and the 1950s. Functionalism, the overall concept of the period, has perhaps been interpreted in terms of ideological concepts, interpreted as "democratic" and as a progressive dividing line between the past and the future.

Sammanfattning : The childhood tumour neuroblastoma is derived from immature cells of the sympathetic nervous system, which have become arrested at different maturation stages. Neuroblastoma is a malignancy with a high degree of heterogeneity, and there is a correlation between a poor differentiation status and a more aggressive phenotype. LÄS MER
5. Device Bonding and Antibody Binding: Developments for On-Chip Differentiation of Induced Pluripotent Stem Cells into Hepatocytes
Sammanfattning : Abstract This thesis describes the bonding optimization of a liver-on-a-chip microfluidic device for evaluation of cultured induced pluripotent stem cell (iPSC)-derived definitive endoderm (DE) cells during their targeted differentiation into mature hepatocytes. Furthermore, it describes the optimization of a number of antibody assays for use during said differentiation, for the purpose of studying the cellular phenotype. LÄS MER
