Abstract

The origin and fate of darkly pigmented clusters of cells that float freely in the brain cavities of the tadpoles of Xenopus laevis have been experimentally investigated. The results point to the conclusion that the clusters are the sites of egg pigment accumulation, which remain within the brain cavities or at its walls until metamorphosis.
