Fetal muscle contains different CD34+ cell subsets that distinctly differentiate into adipogenic, angiogenic and myogenic lineages

► Heterogeneity of CD34+ fetal muscle-derived cells. ► Angiogenic potential of CD34+/CD31+/CD45− cells grafted into adult damaged muscle.► In vitro and in vivo adipogenic differentiation of CD34+/CD31−/CD45−/Sca1+ cells. ► Efficient myogenic potential of CD34+/CD31−/CD45−/Sca1− cells. ► CD34+/CD31−/CD45−/Sca1− myogenic potential enhanced by angiogenic or adipogenic cells.
