“Gastrulation in its broadest sense is the reorganization of the cells of the blastula to form a multilayered embryo, the gastrula.”

“The nucleus must be taken from the blastula and gastrula stages of frog embryos.”

“After the blastula develops, it undergoes transition to the gastrula, a process called gastrulation.”

“At gastrulation, the germ plasm is located in cells in the floor of the blastocoel cavity, among the cells that give rise to the endoderm.”

“In amphibians, there is convergent extension of the future neural plate during gastrulation.”

“At the end of gastrulation, the epidermis only covers the dorsal region and the ventral region is bare.”

“The fine structure of cortical granules in eggs and gastrulae of Mytilus edulis.”

“On the mechanisms of the dorsalization in the ectoderm of Triturus gastrulae caused by precytolytic treatments.”
