[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.
