Origin of the notochord in the rat embryo tail.

The origin of the notochord in the rat tail was investigated on transverse serial semi-thin and ultra-thin sections of 12- and 13-day embryo tails. It was found that the notochord develops from a mass of condensed mesenchymal cells which is located ventrally to the secondary neural tube, and which subsequently splits into a) a thin cord which becomes notochord and b) a thick portion which gives rise to the tail gut. By analogy with the secondary neurulation and the secondary gut formation, one might therefore speak of a secondary notochord formation in the tail. It occurs in close relationship with the formation of the tail gut.
