What is metastasis and angiogenesis?

What is metastasis and angiogenesis?

Angiogenesis, the recruitment of new blood vessels, is an essential component of the metastatic pathway. These vessels provide the principal route by which tumor cells exit the primary tumor site and enter the circulation.

What is osteogenesis and angiogenesis?

Angiogenesis, the formation of new blood vessels, plays a pivotal role in bone development and represents a key contributor to the osteogenesis process. New blood vessel growth is essential during both primary bone development as well as fracture repair in adults.

How are Fibroblast growth factors involved in angiogenesis?

Angiogenic factors, such as fibroblast growth factors (FGFs) and vascular endothelial growth factors (VEGFs), stimulate endothelial cells to secrete several proteases and plasminogen activators, resulting in the degradation of the vessel basement membrane, which in turn allows cells to invade the surrounding matrix.

How are FGF and VEGF function in angiogenesis?

FGF and VEGF function in angiogenesis: signalling pathways,biological responses and therapeutic inhibition TRENDS in Pharmacological Sciences Vol.22 No.4 April 2001 http://tips.trends.com Review201 Angiogenesis denotes the formation of new blood vessels from pre-existing vessels.

What is the role of angiogenesis in embryonic development?

Physiological angiogenesis, which is required for embryonic development, wound healing and the menstrual cycle, is characterized by tight regulation both spatially and temporally.

How does PDGF work in the endothelial cells?

The cells migrate, proliferate and eventually differentiate to form a new, lumen- containing vessel. Finally, the endothelial cells deposit a new basement membrane and secrete growth factors, such as platelet-derived growth factor (PDGF), which attract supporting cells such as pericytes, ensuring the stability of the new vessel1.
