16. Tumor Stroma in Anaplastic Thyroid Carcinoma : Interstitial Collagen and Tumor Interstitial Fluid Pressure
Sammanfattning : Anaplastic thyroid carcinoma (ATC) is an aggressive malignancy in man with stromal fibrosis as one of the main features. Carcinoma cells synthesized no or little collagen I protein. LÄS MER
17. Neural Stem and Progenitor Cells : Cellular Responses to Known and Novel Factors
Sammanfattning : Neural stem cell self-renewal and differentiation are tightly regulated events during CNS development, leading to cell division into new neural stem cells or the formation of neurons and glial cells. This thesis focuses on the cellular responses induced by known and novel factors in neural stem and progenitor cells (NSPCs). LÄS MER
18. The role of 1-intergrins in skeletal muscle differentiation and extracellular matrix assembly
Sammanfattning : Integrin subunit β1 forms heterodimeric receptors with at least 12 different α-subunits.These integrins are the main cellular receptors for extracellular matrix and they arenecessary for normal development. In this thesis, the effects of lack of integrin subunitβ1 on matrix deposition and on skeletal muscle development were studied. LÄS MER
19. Extracellular matrix as a regulator of cell behavior : Biological effects of hyaluronan biosynthesis and catabolism
Sammanfattning : Extracellular matrix surrounding cells is an important regulator of cellular functions. Hyaluronan (HA) is a glycosaminoglyean and a constituent component of the extracellular matrix in all tissues. It is synthesized by hyaluronan syntheses (HAS) at the inner surface of cell membrane and degraded by hyaluronidases to small fragments. LÄS MER
20. Novel chemical and enzymatic routes to the generation of heparin- related polysaccarides
Sammanfattning : Heparin and heparan sulphate (HS) are structurally related polysaccharides influencing various biological processes. The biological functions of heparin/HS largely depend on interactions between the negatively charged polysaccharide chains and a variety of proteins. LÄS MER
