title: Has the yolk an influence on the differentiation of embryonic Drosophila blastemas?
abstract: 1. Anterior and posterior halves of 6 hour-old embryos were transplanted with or without their central egg yolk filling into the abdomens of adult females. 2. It was found that the yolk has no formative or nutritive influence on the differentiation which proceeds normally in the adult milieu.
