Vascular density, angiogenesis and pro-angiogenic factors in uterine fibroids

Angiogenesis is a process of development of new vessels from the preexisting vascular network of a host. This is process which is seen in many physiological situations but it accompanies also a development of different lesions, i.e. neoplasms. Uterine fibroids are one of the most frequent lesions which affect human internal female genital tracts. Authors briefly review most important pro-angiogenic factors, based on their own observation as well as reviewing current literature. They pay much attention to vascular density which is significantly changed in the uterine tumors.
