All through development, There exists a concentration gradient of retinoic acid alongside the anterior-posterior (head-tail) axis. Cells during the embryo respond to retinoic acid differently according to the sum present. By way of example, in vertebrates, the hindbrain transiently varieties 8 rhombomeres and every rhombomere has a particular pattern of genes becoming expressed. If retinoic acid is not present the last 4 rhombomeres will not establish. Alternatively, rhombomeres 1–4 expand to go over the identical level of Area as all eight would Usually occupy.
