Israeli researchers report that embryonic pig tissues used for liver, pancreas, and lung transplants need to come from very specific windows of time in embryonic development. 1 The findings offer new ...

Pancreas development in pigs resembles humans much more closely than does the established mouse model. An international team headed by Helmholtz Munich and the German Center for Diabetes Research (DZD ...

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 ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Animal embryos go through a series of characteristic developmental stages on their journey from a fertilized egg cell to a functional organism. This biological process is largely genetically ...
