Thymosin β4 and angiogenesis: modes of action and therapeutic potential

Abstract
Here we review the mechanisms by which Thymosin β4 (Tβ4) regulates angiogenesis, its role in processes, such as wound healing and tumour progression and we discuss in more detail the role of Tβ4 in the cardiovascular system and significant recent findings implicating Tβ4 as a potential therapeutic agent for ischaemic heart disease.
