Description
In the following experiment, three different hESC cell lines (HES2, MEL1 and H9) were grown in the presence of KOSR, KOSR or mTESR containing media respectively. KOSR (Knockout serum replacement medium) is a standard media allowing the growth of hESC without the need for manual passaging - Enzymatic passaging is used instread. mTESR (Ludwig et al., 2007) is a media allowing the growth of hESC on matrigel with enzymatic passaging. At day 7 after passaging, these cells were FACs sorted for the presence of GCTM-2 and CD9 into 4 distinct fractions (p4: GCTM-2-neg, CD9-neg; p5: GCTM-2-low, CD9-low; p6: GCTM-2-medium, CD9-medium and p7: GCTM-2-high, CD9-high). For each cell line-subfraction combination, RNA was harvested and subject to microarray.
