Skeletal muscle has a capacity for muscular regeneration mediated by satellite cells (SCs) and non-SCs. Although it is proposed that non-SCs are attractive therapeutic targets for dystrophies, the biological properties of these cells remain unclear. We have recently identified novel multipotent pericytes (PCs), capillary stem cells (CapSCs) derived from the microvasculature. In the present study, we determined if CapSCs contributed to myogenic regeneration using
muscular dystrophy
mouse model. CapSCs were isolated as
EphA7

NG2
+
PCs from the subcutaneous adipose tissues of GFP-transgenic mice. Co-culture with C2C12 myoblast cells showed that CapSCs effectively enhanced myogenesis as compared to controls including
EphA7
-
PCs and adipose stromal cells (ASCs). CapSCs transplanted in cardiotoxin-injured gastrocnemius muscles were well differentiated into both muscle fibers and microvessels, as compared to controls. At three weeks after cell-transplantation into the limbs of the mdx/utrn
-/-
mouse, CapSCs increased the number of GFP
+
myofibers along with dystrophin expression and the area size of myofibers, and also enhanced the muscular mass and its performance, assessed by treadmill test as compared to controls. In conclusion, CapSCs have potent myogenic regeneration capacity and improved the pathological condition in a
muscular dystrophy
mouse. Thus, CapSCs are an attractive cellular source in regenerative therapy for
