Comparison of gene change in lymphoma cells after co-culture with endothelial cells

ABSTRACT: Mouse lymphoma cells were co-cultured with endothelial cells in serum/cytokine-free condition. To identify specific genetic changes, we compared lymphoma cells cultured in medium containing 10% fetal bovine serum with lymphoma cells co-cultured with endothelial cells. The experiment compared genetic change in lymphoma cells caused by co-culture with endothelial cells.

Project description:In this work we investigated the molecular mechanisms that sustain the endothelial differentiation of murine embryonic stem cells (ES). When ES cells are co-cultured with the stromal PA6 cells in serum-free medium they differentiate mainly into neurons, thanks to the neural inducing activity exerted by the stroma. The addition of exogenous FGF2 allows also the differentiation of endothelial cells whereas, in presence of exogenous BMP4, ES cells differentiate exclusively into endothelium. The purpose of the gene expression analysis of FGF2 and BMP4 treated co-cultures versus the untreated ones was to profile the transcriptomes of FGF2 and BMP4-driven endothelial differentiation in order to detect molecules and pathways involved upon each of the two exogenous signals. In parallel we also performed transcriptome analysis of single monocultures of stromal PA6 cells to investigate the signals released by the stroma in response to FGF2 and BMP4. We found that TGFb1 is involved in the differentiation of ES cells into endothelium in response to FGF2 while Wnt6 and Wnt pathway sustain the endothelial differentiation of ES cells in response to BMP4.
