"We looked at how certain histones are changed after fertilization ... of these chemical changes occurs, the cell is constrained in its division and development, Torres-Padilla explains.

An international group of plant biologists have succeeded for the first time in visualizing how egg cells in plants divides unequally (asymmetric cell division) after being fertilized. The ...

Actin-dependent spindle positioning and microtubule-dependent positioning of pronuclei have important roles in regulating the symmetry of cell division before and after fertilization. The ...

Right after conception, hundreds of tiny mutations begin to accumulate in cells of a developing fetus, a process that continues, but at a much slower rate, well into adulthood, a new study by ...

But within 24 hours of being fertilized, it starts dividing fast into many cells. It keeps dividing ... tests can detect hCG as soon as 7 days after ovulation.

at least four cycles of cell division occur, giving rise to 16 cells, referred to collectively as the morula. Around 24 hours after fertilization occurs, the first cleavage division occurs.

the central cell must first complete DNA synthesis after fertilization before the first division can begin. This interruption in the cell cycle is caused by a protein in the central cell that is ...

This embryo loss typically occurs in the first two months after fertilization ... variations of different genes can manipulate the cell division process to favor their own transmission to the ...

"It is very surprising that most of these embryo arrests are coming not from errors in egg formation but from errors happening in cell divisions after fertilization ... pre-loaded into the egg control ...

By the third day after fertilization, an embryo has undergone three divisions and contains 16 cells. Each cell division is accompanied by DNA replication, ensuring that each daughter cell contains ...
