The role of complement component C1q in angiogenesis

The complement component C1q plays a role as a pro-angiogenic factor in different contexts, acting in a complement-independent way. For example, this molecule is able to foster the remodeling of the spiral arteries for a physiological pregnancy and to promote the wound healing process. It is also involved in angiogenesis after post-stroke ischemia. Furthermore, it has a role in supporting the tumor vessel growth. Given its role in promoting angiogenesis both under physiological and pathological situations, other studies are needed to understand its potential therapeutic implications.
