Abstract
BACKGROUND Muscle-derived stem cells (MDSCs) contribute to the repair of injured muscles. However, the myogenicity of MDSCs generated from patients with Duchenne muscular dystrophy (DMD) relative to healthy individuals remains unclear. METHODS A human DMD model was established using the stem cells prepared from muscle derived from patients with DMD (DMD-hMDSCs). The expression of myogenic lineage-specific markers in MDSCs was examined with immunofluorescence, real-time polymerase chain reaction, and western blotting. RESULTS It was demonstrated that, compared with cells from healthy subjects, DMD-hMDSCs are primed to self-differentiate in growth-inducing medium (GM) and robustly differentiate into myotubes in differentiation-inducing medium(DM). This feature was termed "myogenesis activation," and it was speculated that it contributes to the depletion of myogenic progenitors. Furthermore, MDSCs consistently express pax7, but the time-course of this expression does not correlate with the expression of the myogenic lineage-specific markers. CONCLUSIONS The myogenesis activation in DMD-hMDSCs demonstrated in this study may provide novel mechanistic insights into DMD pathogenesis and potential therapies.

Abstract
Aging is accompanied by the functional decline of cells, tissues, and organs, as well as, a striking increase in susceptibility to a wide range of diseases. Within a tissue, both differentiated cells and adult stem cells are susceptible to intrinsic and extrinsic changes while aging. Muscle derived stem cells (MDSCs) are tissue specific stem cells which have been studied well for their multipotential nature. Although there are reports relating to diminished function and regenerative capacity of aged MDSCs as compared to their young counterparts, not much has been reported relating to the concomitant gain in unipotent nature of aged MDSCs. In this study, we report an inverse correlation between aging and expression of adult/mesenchymal stem cell markers and a direct correlation between aging and myogenecity in MDSCs. Aged MDSCs were able to generate a greater number of dystrophin positive myofibres, as compared to, the young MDSCs when transplanted in muscle of dystrophic mice. Our data, therefore, suggests that aging stress adds to the decline in stem cell characteristics with a concomitant increase in unipotency, in terms of, myogenecity of MDSCs. This study, hence, also opens the possibilities of using unipotent aged MDSCs as potential candidates for transplantation in patients with muscular dystrophies.

Abstract
Muscle derived stem cells (MDSCs) are multipotent stem cells that can differentiate into several lineages including skeletal muscle precursor cells. Here, we show that MDSCs from myostatin null mice (Mstn (-/-) ) can be readily induced into pluripotent stem cells without using reprogramming factors. Microarray studies revealed a strong upregulation of markers like Leukemia Inhibitory factor (LIF) and Leukemia Inhibitory factor receptor (LIFR) in Mstn (-/-) MDSCs as compared to wild type MDSCs (WT-MDSCs). Furthermore when cultured in mouse embryonic stem cell media with LIF for 95 days, Mstn (-/-) MDSCs formed embryonic stem cell (ES) like colonies. We termed such ES like cells as the culture-induced pluripotent stem cells (CiPSC). CiPSCs from Mstn (-/-) MDSCs were phenotypically similar to ESCs, expressed high levels of Oct4, Nanog, Sox2 and SSEA-1, maintained a normal karyotype. Furthermore, CiPSCs formed embryoid bodies and teratomas when injected into immunocompromised mice. In addition, CiPSCs differentiated into somatic cells of all three lineages. We further show that culturing in ES cell media, resulted in hypermethylation and downregulation of BMP2 in Mstn(-/-) MDSCs. Western blot further confirmed a down regulation of BMP2 signaling in Mstn (-/-) MDSCs in supportive of pluripotent reprogramming. Given that down regulation of BMP2 has been shown to induce pluripotency in cells, we propose that lack of myostatin epigenetically reprograms the MDSCs to become pluripotent stem cells. Thus, here we report the successful establishment of ES-like cells from adult stem cells of the non-germline origin under culture-induced conditions without introducing reprogramming genes.
