Human skeletal muscle tissue displays specific cellular architecture easily
damaged during individual existence, requiring multiple resources for
regeneration. Congruent with local prerequisites, heterogeneous muscle stem cells
(MuSCs) are present in the muscle interstitium. In this study, we aimed to
characterize the properties of human muscle interstitial cells that had the
characteristic morphology of telocytes (TCs). Immunocytochemistry and
immunofluorescence showed that cells with TC morphology stained positive for
c-kit/CD117 and VEGF. C-kit positive TCs were separated with magnetic-activated
cell sorting, cultured in vitro and expanded for study. These cells exhibited
high proliferation capacity (60% expressed endoglin/CD105 and 80% expressed
nuclear Ki67). They also exhibited pluripotent capacity limited to Oct4 nuclear
staining. In addition, 90% of c-kit positive TCs expressed VEGF. C-kit negative
cells in the MuSCs population exhibited fibroblast-like morphology, low
trilineage differential potential and negative VEGF staining. These results
suggested that c-kit/CD117 positive TCs represented a unique cell type within the
MuSC niche.
