FACS of hESC for array analysis. Gates are set relative to isotype controls. A, hESC were separated by FACS according to staining intensity for GCTM-2 and TG30 (CD9) into 4 populations; P4 (GCTM-2^-CD9^-), P5 (GCTM-2^LOWCD9^LOW), P6 (GCTM-2^MIDCD9^MID) and P7 (GCTM-2^HIGHCD9^HIGH). B, heat map depicting normalized intensity of gene expression for genes from P7 V P4 experiment with a B stat greater than zero.
