[Evolution of the homotypic graft of the presumed cardiac area of the quail in the chick].
Employing quail cells as biological labelers, we could easily follow the evolution of the presumptive cardiac area of the quail in the chick blastoderm. If the embryos are operated on in stage 5, the cardiac area fuses completely to that of the host embryo forming a large part of the corresponding half in the definitive heart. On the other hand, in earlier stages the grafted cardiac area contributes only to the formation of island of cells in the resultant heart.
