The last 40 years have witnessed a deep transformation in our views of animal development. From seeing development a multicellular black box where over time a mass of cells acquires shape to form ...

Conditional genetics and single-embryo RNA-seq show that SETDB1 extinguishes the transient, retroelement-driven transcriptional programs of the totipotent two-cell state to facilitate the exit from ...

Development of embryos "We found that the randomness in when and how cells divide actually helps embryos to develop properly," says Dimitri Fabrèges, a postdoc researcher in the Hiiragi group. He and ...

Scientists very rarely get access to most sharks, the development of their young or the nursery grounds where they grow. So seeing a hammerhead shark (Sphyrna tiburo) embryo, halfway through its ...

Despite differences in shape and size all insects are characterized by a body organization that includes three units: a head, thorax and abdomen (panels A-B). In contrast all spiders (and other ...

Researchers have developed a method for culturing fertilized chick eggs without their shells. The eggs were placed in an artificial culture vessel made of transparent film, allowing for real-time ...
