VEGF-B (vascular endothelial growth factor B) is a member of the VEGF family of proteins that regulate the formation of blood vessels. It plays a role in angiogenesis, vasculogenesis, and vascular permeability. Research in the area of VEGF-B focuses on its function in various physiological and pathological processes, such as cardiovascular development, tissue regeneration, and cancer progression. Studies have also investigated the potential therapeutic applications of VEGF-B in treating cardiovascular diseases and other conditions related to vascular dysfunction. Overall, research on VEGF-B contributes to our understanding of blood vessel formation and maintenance, and has implications for the development of novel therapeutic interventions.
