1. Molecular mechanisms of embryonic stem cell pluripotency: transcription, telomere maintenance and proliferation
Sammanfattning : Somatic cell nuclear transfer and generation of induced pluripotent stem cells provide potential routes towards generation of patient specific embryonic stem (ES) cells. These procedures require induction of Oct4 gene expression, high telomerase activity and specific cell proliferation, characteristics shared with cancer stem cells. LÄS MER
2. Stem cell function and organ development : analysis of Lhx2 function in hematopoietic stem cells and eye development
Sammanfattning : When a multicellular organism suffers damages to tissues/organs it heals itself by either substituting the lost cellular matrix by scar formation or by regenerating the lost tissue. Regeneration likely occurs by a recapitulation of the developmental process that formed the organ. LÄS MER
3. Identification of stem cell factors - Novel protein-protein interactions and their functions
Sammanfattning : Embryonic stem (ES) cells provide an unlimited source of cells potentially useful for regenerative medicine, however, prior to clinical implementation, additional basic research is needed. This thesis is focused upon different molecular aspects regarding ES cells, primarily by finding novel stem cell protein-protein interactions and their functions. LÄS MER
4. Regulation of the vascular smooth muscle cell phenotype
Sammanfattning : Smooth muscle cells (SMC) are present in many internal organs such as the blood vessels and the gastrointestinal channel. Their main functions are to provide stability to the tissue and to provide contractile capability. SMC are not terminally differentiated but can switch between several phenotypes, which is also known as phenotypic modulation. LÄS MER
5. Towards Generation of Human Hematopoietic Stem Cells from Pluripotent Stem Cells
Sammanfattning : There is a pressing need for compatible Hematopoietic Stem Cells (HSCs), in high quantities and of good clinical quality, to ensure optimal treatment for patients with various blood malignancies. Pluripotent Stem Cells (PSCs) have the potential to be a source for generating HSCs. LÄS MER
