PW1/Peg3 is expressed in satellite cells as well as a subset of interstitial cells with myogenic potential termed PICs (PW1+ Interstitial Cells). PICs differ from satellite cells by their anatomical location (satellite cells are sublaminal and PICs are interstitial), they do not express any myogenic marker and arise from a Pax3-independent lineage. Upon isolation from juvenile muscle (1 to 3 weeks old), PICs are capable to form both skeletal and smooth muscle suggesting they constitute a more plastic population compared to satellite cells. We used microarrays to gain insight into the relantionship between PICs and satellite cells. PICs and satellite cells were isolated from 1-week old mouse muscle and subsequent RNA extraction was performed.", "source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-40523", "sample_source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-40523/samples/"}
