Studying embryogenesis is key to unraveling the mysteries of early life. luismmolina/iStock via Getty Images Plus Embryonic development, also known as embryogenesis, is a cornerstone in understanding ...

The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller ...

Lab-grown structures with the potential to develop into fetuses should be defined — and regulated — as embryos, some researchers say. It is time for a redefinition of the human embryo, a team of ...

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

A human embryo-like model was successfully developed by a group of scientists at the California Institute of Technology, led by renowned biologist Madalena Zernicka-Goetz. The model replicates the ...

STANFORD, Calif. (KGO) -- In the Camarillo bioengineering lab at Stanford, engineers measure impacts both big and small. And that ability can help in research as far ranging as preventing concussions ...

Under his microscope, Jun Wu could see several tiny spheres, each less than 1 millimetre wide. They looked just like human embryos: a dark cluster of cells surrounded by a cavity, and then another ...

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

High-resolution 3D womb model gives insights into embryo implantation, infertility, and signals between embryo and mother, ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...
