Automated minute scale RNA-seq of pluripotent stem cell differentiation reveals early divergence of human and mouse gene expression kinetics

Experiment overview and expression patterns.
A) Mouse and human pluripotent stems cells were exposed to neural differentiation factors to initiate differentiation and then sampled for RNA-sequencing every 4 or 10 minutes for the first 600 minutes. Expression trends along the time course for each gene were fit using a breakpoint model. B) Expression trends are shown for representative genes having patterns classified as not dynamic, immediate dynamic, or delayed dynamic. Immediate dynamic genes had an immediate up- or downregulation segment, whereas delayed dynamic genes had a flat initial segment. Trends were further characterized as having a peak, dip, or as cyclic (multiple peak/dip) (Methods).
