Project description:Primary colon CSC cultures were transduced with a Wnt responsive construct (TOP-GFP). 10% highest and lowest TOP-GFP cell fractions were FACS sorted and arrayed. Primary colon CSC cultures with a responsive construct (TOP-GFP): high and low TOP-GFP cell fractions. 12 samples.

Project description:Primary colon CSC cultures were transduced with a Wnt responsive construct (TOP-GFP) and were single cell cloned. 10% highest and lowest TOP-GFP cell fractions were FACS sorted and arrayed. Primary colon CSC cultures with a responsive construct (TOP-GFP): high and low TOP-GFP cell fractions. 4 samples.

Project description:Colon cancers typically contain tumor cell populations with differential WNT signaling activity. Colon cancer cells with high WNT-activity have been attributed increase tumorigenic potential and stem cell characteristics. We extracted tumor cells with differential WNT activity using fluorescent reporters from xenografted human colon cancer cell line tumors and primary human colon cancer xenografts and analysed their gene expression profiles. Colon cancer cell lines and primary colon cancer xenografts were transduced with lentiviral TOP-GFP reporters, and grown as xenografts in NOD-SCID mice. We disaggregated these tumors, flow sorted for GFPhigh and GFPlow tumor cells and subjected these populations to gene expression profiling.
Project description:We report here the transcriptome of sorted cells from a Guca2a promoter GFP mouse model, positve and negative cells for GFP from 4 different regions of the GI tract, duodenum (top 3cm), jejunum (intermediate small intestine), ileum (bottom 10 cm) and colon +rectum from 3 different mice. This data allows the characterization of the cells expressing Guca2a at the trancriptome level, revealling expression of different cell markers and showing diversity of Guca2a producing cells along the GI tract.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
