Project description:Anaplastic Large Cell Lymphoma (ALCL) is propagated by cancer stem cells which are identified by their ability to efflux dye and hence reside in the side population (SP) on FACS analysis. In order to understand the origins of these ALCL SP cells we purified SP and main population (MP; SP-depleted) cell from the ALCL cell line SUDHL-1. On comparison of the gene expression signatures derived from these 2 cellular populations distinct branches dividing the SP and MP populations present indicating that they are distinct subsets within the bulk tumour. We sought to obtain pure populations of SP and MP cells from human SUDHL-1 Anaplastic Large Cell Lymphoma (ALCL) cell line. SUDHL-1 cells were stained with Hoechst 33342 dye, analysed using MoFlo Cell Sorter with UV lasers. The cells were then sorted in triplicates and subjected to RNA extraction. The extracted RNA was subjected to gene expression microarray using the Affymetrix Human Gene 1.0 ST Array.
Project description:Using Affymetrix GeneChips, we analyzed expression profiles of SP cells from EOM and TA. 348 differentially expressed transcripts defined the EOM-SP transcriptome: 229 upregulated in EOM-SP and 119 in TA-SP. Keywords: Expression Profiling
