Expression of PcG protein transcripts in KIND1 cells grown on HFF and feeder free KIND1 cells. qRT-PCR results show expression of (A) PRC1 group members- RING1A, RING1B, BMI1 and CBX2 (B) PRC2 group members SUZ12, EZH2, EED and JARID2 in KIND1 cells cultured on human feeder fibroblasts (HFF). qRT-PCR results showing expression of (C) PRC1 group members- RING1A, RING1B, BMI1and CBX2 (D) PRC2 group members SUZ12, EZH2, EED and JARID2 in feeder free KIND1 cells. The expression is with respect to highest detectable (Ct 40). Error bars represent ± SEM.
