Temporal transcriptomic expression for five separate C. elegans blastomeres lines. From the 2-cell stage (two blastomeres), through the 8-cell (five blastomeres lines: AB,E,MS,C,P+D) and an overnight incubation.
For a detailed description of the experimental design see 'Spatiotemporal embryonic transcriptomics reveals the evolutionary history of the endoderm germ layer' (Hashimshony et al, Nature 2015).
