[Experimental analysis of cardiac regulation in the chick embryo].
Homochronous homografts of prospective cardiac area labeled with 3H thymidine have been carried out in chicken embryos at stages 5 and 6 of Hamburger and Hamilton. It has been observed how a heart tube or a vesicle, sometimes contractile, is developed by the graft. This vesicle, which is partly joined or not joined, to the receptor's heart, is always in close dependence on the pharynx normogenesis.
