Morphogenesis (meaning the "beginning of shape"), is the biological process that causes an
organism to develop its shape.
It is one of three fundamental aspects of
developmental biology along with the control of
cell growth and
The process controls the organized spatial distribution of cells during the
embryonic development of an
organism. Morphogenetic responses may be induced in organisms by
hormones, by substances produced by other organisms, or by mechanical stresses induced by spatial patterning of the cells. Morphogenesis can take place in an embyro, a mature organism, in cell culture or inside tumor cell masses.
