Project description:Bone marrow-derived multipotent stromal cells (BM-MSCs) exhibit therapuetically valuable properties, including the capacity to differentiate into skeletal tissues and modulate immune system activity. These properties depend on proper regulation of dynamic gene expression in response to environmental and developmental stimuli. This study used chromatin immunoprecipitation (ChIP) coupled with human promoter tiling microarray analysis (ChIP-on-chip) to profile histones H3K4me3 and H3K27me3 at promoters genome-wide. The goal of the study was to identify gene promoters marked by H3K27me3 and H3K4me3 in BM-MSCs. ChIP-on-chip performed with antibodies to H3K4me3 and H3K27me3 on BM-MSCs from 3 different donors (labeled 1632, 167696, and 8F3560) and with technical replicates.

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.
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.

Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.
