The results are helping scientists better understand foundational questions about egg cell development and cellular transport. "Our findings represent a big leap in this field," says co-author ...

Scientists at a technology company said Sunday they have created human embryos through cloning, drawing criticism from President Bush and lawmakers and raising new ethical questions. Advanced Cell ...

Researchers from the University of Adelaide have discovered that the earliest days of embryo development have a measurable ...

During early development the precursors to all these ... its nucleus inserted into an enucleated egg cell that is stimulated to begin dividing, and the resulting blastocyst-stage embryo then ...

Embryonic stem cells are pluripotent, meaning that they have the ability to differentiate, or change, into many directions. Embryonic development Development starts with a fertilized egg cell, which ...

The findings help elucidate what happens during the earliest periods in development. “I was always interested in how cells decide their fate,” Zernicka-Goetz said. In the mouse developing embryo, she ...

Because these blastoids only use ESCs derived from the epiblast, which becomes the embryo proper with germ layers, they model embryonic development’s pre-implantation period, up to seven days post ...

Stem cell-derived embryo models offer insights into early development but suffer from variability. Here, authors used AI to classify and predict outcomes for generation of mouse stem cell-derived ...
