Science Art: Optical projection tomography: OPT analysis of Smoc1 expression in wild-type E9.5 mouse embryo, 2011

Scientific illustration of a mouse embryo, taken with optical projection tomography, showing how loss of the BMP Antagonist expresses itself in syndactyly - in other words, a syndrome in which gene differences affect how fingers and toes grow.

This is a video of a mouse, not yet born, already has some issues specifically “Waardenburg-Anophthalmia Syndrome.” It’s originally from a PLOS genetics paper, but I found it on Wikimedia Commons, while trying to figure out what exactly Optical Projection Tomography really was (basically using visual light to study things “sectionally,” I guess – it must be really bright light, I suppose).
