[Experimental study of the precocious formation of the endothelial wall in bird embryos].

Pieces of ectomesoderm from the area pellucida of primitive streak stages don't give normal endothelium when transplanted on ectoderm of the area opaca. Endothelium is able to differenciate from mesoderm transplanted with endoderm. Mesenchyme from the primitive streak migrating between the endoderm and the ectoderm of the host always gives endothelial tubes.

[Induced degeneration and lysosome activity in the cells of the tail bud in the early chick embryo].

In chick embryos, cells of the tail bud are induced to degenerate by autophagocytosis when treated by puromycine or sodium fluoride. Although these degenerative processes exhibit some differences, according to the nature of the inhibitor used, their initial steps, which consist in a modification of the Golgi zone, are identical. These facts are discussed in relation to the problem of morphogenetic cell degeneration.

[Early teratogen effect of neutral desoxyribonuclase on young chick embryo].

Neutral DNA-ase acts as a general teratogen when given to young chicken blastoderms. The rate of the differents abnormalities varies according to the dose given and the embryos' stage. The frequency of the different defects reaches a maximum value with increasing doses it falls generally down with more important doses. DMSO added to the enzyme solution changes the susceptibility of the embryos.
