The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller ...

Researchers have gained new insights into the mechanism behind the spatial organization of DNA within the cells of early embryos. When an embryo is first formed after fertilization, each cell has the ...

Researchers at Dresden University of Technology reveal that early zebrafish embryos divide without a closed actin ring.

Researchers at the Babraham Institute have ‘listened in’ to the communication between the embryo and the womb lining at the ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early ...

The mystery of early embryonic communication is starting to be unraveled thanks to a new stem cell-based model.

For decades, scientists have struggled to study this moment in humans because of ethical restrictions and limited access to ...

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

Image of mouse embryos at the 2-cell stage visualised by light microscopy. Two blastomeres (cells) can be seen inside the zona pellucida (a “shell-like” protective outer layer) of each embryo. Credit: ...

Although embryonic stem cells (ESCs) have been successfully derived from mice and rats, efforts to establish chimeric and germline-competent ESC lines in species beyond rodents have been unsuccessful.
