It's one of life's most defining moments - that crucial step in embryonic development, when an indistinct ball of cells rearranges itself into the orderly three-layered structure that sets the stage ...

Researchers at Sinai Health have found that a critical transition in early human development is regulated not by our genes, but by DNA elements called transposons that can move around the genome. The ...

For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic ...

China sent synthetic human embryos to its space station this month, the first experiment of its kind. The goal is to determine whether one of the earliest stages of human development can withstand ...

Researchers reveal that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of infertility and early human development. CRCHUM researcher Sophie ...

The images show the inside of the cell nucleus at an 8-cell stage (left) and at a later stage (right). Chromosome 19 is shown in red whereas the nucleolus containing the gene-silencing machinery is in ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

Pea-sized brain blobs are a chatty bunch. Packed with neurons that spark with electrical activity, brain organoids—or “mini brains”—are a now popular way to study the human brain. Some organoids model ...
