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 ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Scientists captured first real-time 3D video of human embryo implantation, revealing mechanical forces behind successful ...

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 ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development—including the production ...

Scientists have developed an experimental way to study how human embryos implant in a uterus, which may provide new insights into why miscarriages occur and how they can be prevented.

A cell aggregation of human pluripotent stem cells and amniotic ectoderm cells generated by the published culture method and mimicking the gastrulation event in human embryos. Gray: nuclei, Cyan: ...

Researchers have discovered a potential 'pause button' in the earliest stages of human development. Whether humans can control the timing of their development has long been debated. The new study ...

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 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 - ...
