1. THE ROLE OF BMP SIGNALING AND ENDOGLIN IN REGULATION OF HEMATOPOIESIS
Sammanfattning : Hematopoiesis, the formation of blood cells, ultimately depends on a rare population of hematopoietic stem cells (HSCs), which can both self-renew to maintain the HSC pool, and differentiate into all mature blood lineages. HSC fate decisions are governed by a complex combination of numerous signals, although the molecular mechanisms are not fully understood. LÄS MER
2. Heparan sulfate dependent cell signaling and associated pathophysiology : Implications in tumorigenesis and embryogenesis
Sammanfattning : Heparan sulfate proteoglycans (HSPGs) consist of a protein core to which several linear, negatively charged heparan sulfate (HS) chains are covalently attached. HSPGs are expressed on the cell surface and in the extra-cellular matrix (ECM) where they have diverse biological functions, for example co-receptor functions. LÄS MER
3. BMP - a key signaling molecule in specification and morphogenesis of sensory structures
Sammanfattning : Cranial placodes are transient thickenings of the vertebrate embryonic head ectoderm that will give rise to sensory (olfactory, lens, and otic) and non-sensory (hypophyseal) components of the peripheral nervous system (PNS). In most vertebrate embryos, these four sensory placodes undergo invagination. LÄS MER
4. Studies of PDGF receptor signaling in vitro and in vivo
Sammanfattning : Platelet-derived growth factor receptor (PDGFR) signaling is essential for proliferation, migration and survival of cells of mesenchymal origin; however, its deregulation has been associated with various diseases, including cancer. The aim of this thesis was to clarify the molecular mechanisms of PDGFR signaling regulation. LÄS MER
5. Signaling mechanisms underlying neural stem cell differentiation. Implications of BMPs, retinoids, and MAP kinases
Sammanfattning : Introduction: Neural stem cells are proliferating cells, derived from the nervous system with the ability to give rise to neurons, astrocytes, and oligodendrocytes. The molecular events and signaling pathways regulating neural stem cell differentiation are largely unknown. LÄS MER
