Abstract
Skeletal muscle is the most abundant human tissue; therefore, an unlimited availability of myogenic cells has applications in regenerative medicine and drug development. Here we detail a protocol to derive myogenic cells from human embryonic stem (ES) and induced pluripotent stem (iPS) cells, and we also provide evidence for its extension to human iPS cells cultured without feeder cells. The procedure, which does not require the generation of embryoid bodies or prospective cell isolation, entails four stages with different culture densities, media and surface coating. Pluripotent stem cells are disaggregated to single cells and then differentiated into expandable cells resembling human mesoangioblasts. Subsequently, transient Myod1 induction efficiently drives myogenic differentiation into multinucleated myotubes. Cells derived from patients with muscular dystrophy and differentiated using this protocol have been genetically corrected, and they were proven to have therapeutic potential in dystrophic mice. Thus, this platform has been demonstrated to be amenable to gene and cell therapy, and it could be extended to muscle tissue engineering and disease modeling.

Abstract
Mesoangioblasts are stem/progenitor cells derived from a subset of pericytes found in muscle that express alkaline phosphatase. They have been shown to ameliorate the disease phenotypes of different animal models of muscular dystrophy and are now undergoing clinical testing in children affected by Duchenne's muscular dystrophy. Here, we show that patients with a related disease, limb-girdle muscular dystrophy 2D (LGMD2D), which is caused by mutations in the gene encoding α-sarcoglycan, have reduced numbers of this pericyte subset and thus produce too few mesoangioblasts for use in autologous cell therapy. Hence, we reprogrammed fibroblasts and myoblasts from LGMD2D patients to generate human induced pluripotent stem cells (iPSCs) and developed a protocol for the derivation of mesoangioblast-like cells from these iPSCs. The iPSC-derived mesoangioblasts were expanded and genetically corrected in vitro with a lentiviral vector carrying the gene encoding human α-sarcoglycan and a promoter that would ensure expression only in striated muscle. When these genetically corrected human iPSC-derived mesoangioblasts were transplanted into α-sarcoglycan-null immunodeficient mice, they generated muscle fibers that expressed α-sarcoglycan. Finally, transplantation of mouse iPSC-derived mesoangioblasts into α-sarcoglycan-null immunodeficient mice resulted in functional amelioration of the dystrophic phenotype and restoration of the depleted progenitors. These findings suggest that transplantation of genetically corrected mesoangioblast-like cells generated from iPSCs from LGMD2D patients may be useful for treating this type of muscular dystrophy and perhaps other forms of muscular dystrophy as well.

Abstract
The signals that direct pluripotent stem cell differentiation into lineage-specific cells remain largely unknown. Here, we investigated the roles of BMP on vascular progenitor development from human embryonic stem cells (hESCs). In a serum-free condition, hESCs sequentially differentiated into CD34+CD31-, CD34+CD31+, and then CD34-CD31+ cells during vascular cell development. CD34+CD31+ cells contained vascular progenitor population that gives rise to endothelial cells and smooth muscle cells. BMP4 promoted hESC differentiation into CD34+CD31+ cells at an early stage. In contrast, TGFbeta suppressed BMP4-induced CD34+CD31+ cell development, and promoted CD34+CD31- cells that failed to give rise to either endothelial or smooth muscle cells. The BMP-Smad inhibitor, dorsomorphin, inhibited phosphorylation of Smad1/5/8, and blocked hESC differentiation to CD34+CD31+ progenitor cells, suggesting that BMP Smad-dependent signaling is critical for CD34+CD31+ vascular progenitor development. Our findings provide new insight into how pluripotent hESCs differentiate into vascular cells.
