Changes in adipose tissue mass must be accompanied by parallel changes in
microcirculation. Investigating the mechanisms that regulate adipose tissue
angiogenesis could lead to better understanding of adipose tissue function and
reveal new potential therapeutic strategies. Angiogenesis is defined as the
formation of new capillaries from existing microvessels. This process can be
recapitulated in vitro, by incubation of tissue in extracellular matrix
components in the presence of pro-angiogenic factors. Here, we describe a method
to study angiogenesis from adipose tissue fragments obtained from mouse and human
tissue. This assay can be used to define effects of diverse factors added in
vitro, as well as the role of endogenously produced factors on angiogenesis. We
also describe approaches to quantify angiogenic potential for the purpose of
enabling comparisons between subjects, thus providing information on the role of
physiological conditions of the donor on adipose tissue angiogenic potential.
