In this stage, a single layer of cells gives rise to three separate germ layers, which later in development become specific tissues and organs. The various colours were added by Jia Le Lim, predoctoral fellow in EMBL Barcelona\u2019s Trivedi group, who studies the effect of temperature on vertebrate embryo development.<\/p>\n\n\n\n<p>To obtain this image, Lim stained mRNA transcripts responsible for ensuring the relative proportions of the three germ layers using a multiplexed, quantitative method&nbsp; called <em>in-situ<\/em> hybridisation chain reaction. In addition to investigating how developmental rates scale with temperature, she is interested in figuring out why development fails above and below an organism&#8217;s optimal temperature range.
