The Sox2 protein is an early marker of neural tissue. Imagine a researcher removes a region of cells from an area of a gastrulating embryo he believes to be neural-specified, and places them in neutral culture medium; however, he doesn't observe any Sox2 expression after several days, and the cells do not take on a neuron-like appearance.
