Gene expression profile. (a) Genes displaying gain (▪, left), loss (▪, right) or differential expression (□, up-regulated on the left and □, down-regulated on the right) in m17.ASC cells (vertical axis) compared with the SVF derived from subcutaneous adipose tissue (SVF, horizontal axis) by microarray. The scatterplot shows normalized microarray datasets of m17.ASC and SVF. All 45,281 gene probes are represented in this plot. (b) Gene expression changes in m17.ASC and nCM versus SVF are correlated. Genes previously selected for up- and down-regulation in m17.ASCvs SVF cells are plotted for their m17.ASC/SVF log2 ratio expression on the x-axis, and their nCM/SVF Log2 ratio expression on the y-axis. nCM, neonatal cardiomyocytes.
