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

Research shows how the curved shape of a zebrafish egg sets cell division timing, gene activation, and early cell fate ...

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 ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

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

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...

The little clump of cells looked almost like a human embryo. Created from stem cells, without eggs, sperm, or a womb, the embryo model had a yolk sac and a proto-placenta, resembling a state that real ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...
