Sammanfattning : The cardiovascular system is the first functional organ to develop during embryogenesis. As the embryo reaches above a certain size, passive diffusion of gases and nutrients is no longer compatible with efficient growth. LÄS MER
2. Hypoxia-inducible factors (HIFs) and biological responses, in hypoxia, inflammation and embryonic vascular development
Sammanfattning : ABSTRACT Low oxygen tension (hypoxia) is a major inducer of neovascularisation and evidence emerging has indicated that oxygen tension and hypoxia-inducible factors (HIFs), a family of oxygen-regulated heterodimeric transcription factors, may play important roles in vascular and hematopoietic development. This thesis has focused on studying molecular and cellular mechanisms, by which cells and organisms sense changes in oxygen tension, and how this signal is transduced by HIFs into downstream signalling.

Sammanfattning : Blood vessels transport blood with essential nutrients and oxygen to the cells in our body. In a healthy adult, formation of new vessels (angiogenesis) occurs only in case of tissue repair and growth. LÄS MER
Sammanfattning : The present study was conducted in order to assess a role of the SH2 domain-containing adapter protein SHB in development and cell differentiation.Embryonic stem (ES) cells overexpressing SHB and SHB with an inactive SH2 domain (R522K-SHB) were obtained. LÄS MER
5. Studies of the vascular endothelial growth factors, VEGFs, and their receptors, focusing on VEGF-B
Sammanfattning : The inner lining of all blood- and lymphatic vessels are composed of endothelial cells. Their growth and differentiation are in part regulated by polypeptide growth factors and their receptors. LÄS MER
