AREG and myocardial infarction: Recent evidence shows that these cells contain potent regenerative proteins, such as amphiregulin (Liu et al. 2022; Zaiss et al. 2015) which can promote tissue repair through epidermal growth factor signalling (Zaiss et al. 2015) and have been implicated in myocardial muscle repair post-myocardial infarction (Zhuang et al. 2022) as well as wound healing (Zaiss et al. 2019).
