Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...

The development of an embryo is one of the most fundamental processes in biology. Early in this process, it is determined ...

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 ...

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 ...

Meet Cody Robb, an IVF baby who became an embryologist to help others build families. Read his inspiring story and learn about IVF advancements.

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 - ...

Eating large amounts of ultra-processed food (UPF) is linked not only to reduced fertility in men, but also to slower growth in early embryos, and smaller yolk sacs, which are essential for early ...

Neurodevelopment involves the brain's formation of systems responsible for learning, memory, social skills, and overall function. Critical neurodevelopmental processes such as neurogenesis, synaptic ...
