Gene Expression Profiles of tumor sorted fractions demarcating cancer stem cell heirarchy using PKH dye in ovarian cancer xenograft tumor

ABSTRACT: Our earlier report states isolation of ovarian cancer stem cell heirarchy using membrane labeling PKH26/67 dyes (Kusumbe and Bapat Cancer Research. 2009) in a xenograft model. We earlier reported that ovarian cancer is a stem cell disease with isolation of cell line (A4T) from a patient with Grade IV serous adenocarcinoma (Bapat et al. Cancer Research. 2005). A4T cells were labelled with PKH26 membrane labeling dye, flourescence intensity was quantified and set as 100% dye retaining cells (PKHhi) with flow cytometery. 2.5x10^6 P65 A4PKH26 labeled cells were injected s.c in NOD/SCID mice, while unlabeled cells were also injected for generation of control tumors . Mice were observed for tumor formation and tumors were harvested at day 28 (4 weeks) and processed for collagenase digestion fo
