Project description:We quantified protein expression changes between epithelial and mesechymal stages in immortalized human mammary epithelial cells (HMLE). Epithelial–mesenchymal transition is induced by expressing an EMT-TF, Twist.
Project description:For gene expression profiling, we used immortalized human mammary epithelial cells (HMLE) to isolate a pure epithelial fraction of cells by positive selection for CD24 expression using Magnetic Activated Cell Sorting (=24hi). We independently isolated 3 mesenchymal subpopulations (msp1-3) from HMLE cells by collecting floating cells from cultured monolayer HMLE cells.

Project description:Merlin has been implicated in contact-dependent inhibition of proliferation To define genes regulated by Merlin and study their relationship to cell density-dependent gene expression, microarray experiments were performed after Merlin depletion in HMLE cells at both high and low cell densities. HMLE are non-transformed immortalized human mammary epithelial cells (Elenbaas et al., Genes Dev 15, 2001)

HMLE are non-transformed immortalized human mammary epithelial cells (Elenbaas et al., Genes Dev 15, 2001) HMLE cells were transfected with NF2 or scramble (control) siRNAs. 2 days later medium was changed (dense) or cells seeded in sparse conditions and RNA isolated the day after (3 days after siRNA transfection)
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.
