Fluorescence micrograph of a fertilized egg of the African clawed frog (Xenopus laevis) in the gastrula stage of development, showing the cellular alignment. The gastrula stage is marked by the invagination of the endoderm layer inside the blastocoel to form the archenteron, or primitive gut, which will become a digestive cavity. (c) Michel Delarue
