The fundamental improvement of muscle ischemia requires the re-establishment of sufficient vessel network. Despite many kinds of drugs have been used for ischemia, effective angiogenic drug is very limited. Here, we reported the identification and isolation of a potent angiogenic fraction (angio-T) from Geum japonicum and assessment of its therapeutic effects on muscle ischemia by reconstituting the insufficient blood supply network and enhancing cell survival potential. It was demonstrated that angio-T not only significantly enhanced the proliferation of cultured HCAECs in vitro, but also significantly enhanced the survival potential of the myofibers at risk and neovascularization in ischemic muscles leading to reconstitution of these vessel networks, significant reduction of ischemic areas, and significant myofiber regeneration in ischemic area one week post-ischemia.
