Clumps of embryonic stem cells given one brief molecular stimulation start arranging themselves in a way that resembles a mouse embryo, down to the timing of when the cells switch on particular ...

The earliest stage of human embryo development—known as pre-implantation—is a critical window. During this phase, the first ...

Researchers at the Center for Embryology and Healthy Development (CRESCO) aim to find out why so many early embryos fail in their development. New insights into how maternal and paternal DNA is ...

After a sperm fertilizes an egg, the totipotent cell divides into a zygote. As division continues, some cells divide into the growing mass, distinguishing cells that form the embryo (epiblast) from ...

Researchers at Karolinska Institutet have developed a method that shows how the nervous system and sensory organs are formed in an embryo. By labelling stem cells with a genetic ‘barcode’, ...

The team found that 80% of the stem cells organize themselves into a structure that mimics the most basic form of an embryo after a few days, and most undergo gene activation that reflects the ...
