ANGPT1 and ischemia: Although Ang-1 has been shown to have effects on MPCs (Dallabrida et al., 2005; Wagatsuma, 2007; Abou-Khalil et al., 2009; Volz et al., 2012; Mofarrahi et al., 2015), its effects are still somewhat controversial, and little is known about its effects on muscle regeneration in the context of ischemia.
