Mammalian Organ Development (IMAGE) Heidelberg University Caption The research group of professor Dr. Henrik Kaessmann investigated the activity (expression) of genes across mammalian organ development. The figure (cube) illustrates the three main biological dimensions of the work: species, organs and developmental stages. The evolutionary relationships of species are indicated in a tree on the left frontal surface of the cube, while the expression of an exemplary gene across development in different organs is indicated on the right frontal surface.
