| Title |
Expression data from undifferentiated and iPS cells differentiated to a myogenic fate [hPAX7] |
| Organism |
Homo sapiens |
| Experiment type |
Expression profiling by array
|
| Summary |
Here, we report the generation of human induced Pluripotent Stem (iPS) cell reporter line in which a venus fluorescent protein have been introduced into the PAX7 locus. We use microarrays to compare the transcriptome of PAX7-venus+ cells after 3 weeks of myogenic differentiation to that of undifferentiated iPS
Satellite cells (SC) are muscle stem cells which can regenerate adult muscles upon injury. Most SC originate from PAX7-positive myogenic precursors set aside during development. While myogenesis has been studied in mouse and chicken embryos, little is known about human muscle development. Here, we use microarrays to compare the transcriptome of myogenic cells differentiated in vitro from human and mouse ES and iPS cells reporter cell lines. We generated fluorescent reporter lines in which a fluorescent protein was introduced into the loci coding for Pax7 (mouse ES and human iPS) or MYOG (human iPS). Mouse ES and human iPS cells were differentiated to the myogenic lineage in vitro for three weeks according to the protocols described in Chal et al, Nature Biotech 2015 and to Chal, Al Tanoury et al, Nature Protocols, 2016. Fluorescent Pax7 or MYOG-positive cells were FACS-sorted after 3-weeks of differentiation in vitro and we used Affymetrix microarrays to analyze the transcriptome of the purified mouse and human cell populations and compare it to the transcriptome of undifferentiated mouse ES or human iPS cells.

| Overall design |
iPS lines were differentiated according to previously described protocols (Chal et al., 2016; Chal et al., 2015). Venus+ cells were purified by FACS from 3-weeks old differentiated cultures and samples were compared to undifferentiated pluripotent iPS cells
