1. VEGFR-2 in Endothelial Differentiation and Vascular Organization
Abstract : 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. READ MORE

2. Modulation of Angiogenesis by Laminins and Heparan Sulfate
Abstract : 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. READ MORE

3. Hypoxia-inducible factors (HIFs) and biological responses, in hypoxia, inflammation and embryonic vascular development
Abstract : 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.

4. Stem cell function and organ development : analysis of Lhx2 function in hematopoietic stem cells and eye development
Abstract : 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. READ MORE

5. Angiogenic growth factors : mechanism of action and function in vascular development
Abstract : The mature vascular system is composed of a network of blood vessels organized into arteries, capillaries, and veins. The vessels are composed of endothelial cells surrounded by smooth muscle cells and embedded in a specialized basement membrane. READ MORE
