Abstract:
Angiogenesis, defined as the growth of new blood vessels from existing ones, plays a key role in development, growth, and tissue repair. Its necessary role in tumor growth and metastasis has led to the creation of a new category of anti-angiogenic cancer therapies. Preclinical development and evaluation of potential drug candidates require models that mimic real microvascular networks. Here, we describe the rat mesentery culture model as a simple ex vivo assay that offers time-lapse imaging of intact microvascular network remodeling and demonstrate its application for anti-angiogenic drug testing.
