Scanning EM of a 24 hr (prim-5) zebrafish embryo. Zebrafish were chemically fixed critically point dried, and sputter coated with gold/palladium. This image is part of a series taken by Bryan Crawfo...

Confocal image of the developing eye of a chick embryo. The dark region in the centre is the where the surface layer has invaginated to form the lens vesicle. The tissue surrounding this space is stai...

This movie is of a Drosophila melanogaster early embryo (cycle 10-12) expressing a GFP-tagged centrosomal protein called TACC (transforming, acidic, coiled-coil protein). GFP-TACC marks the movement a...

Camera lucida sketches of the zebrafish embryo at selected stages. This image is in the Cleavage period at the 1.5 hour 16 cell stage. The animal pole is to the top for the early stages, and anterior...

Camera lucida sketches of the zebrafish embryo at selected stages. This image is in the Blastula period at the 3 hour 1000 cell stage. The animal pole is to the top for the early stages, and anterior ...

Camera lucida sketches of the zebrafish embryo at selected stages. This image is in the Gastrula period at the 6 hour shield stage. The animal pole is to the top for the early stages, and anterior is ...

Camera lucida sketches of the zebrafish embryo at selected stages. This image is in the Gastrula period at the 9 hour 90% epiboly stage. The animal pole is to the top for the early stages, and anterio...

Camera lucida sketches of the zebrafish embryo at selected stages. This image is in the Segmentation period at the 12 hour 6 somite stage. The animal pole is to the top for the early stages, and anter...

Spinning disk confocal time-lapse imaging of the first mitosis in a C. elegans embryo expressing GFP-KNL-2 in which CeCENP-C was depleted by RNAi in strain OD31. Discrete foci of GFP signal within the...

Confocal micrograph of a Drosophila embryo stained for Pax3/7 (cyan), eve, horse radish peroxidase (red) and counterstained with DAPI (blue). Pax3/7 genes encode a class of transcription factors that...
