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 - ...

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 ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

Then researchers placed blastoids and embryos donated after infertility treatments inside the little device and watched it under a microscope. A human blastoid is a stem-cell-made copy of an early ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

The mystery of early embryonic communication is starting to be unraveled thanks to a new stem cell-based model.

Scientists have developed an experimental way to study how human embryos implant in a uterus, which may provide new insights ...

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 ...

Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into synthetic uterine tissue—revealing a key stage in reproduction. The resulting ...

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and Stanford University have been able to study the implantation of human ...
