An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic ...

Men have nipples because embryos are sexually neutral for their first six weeks. Here's the developmental blueprint behind ...

In recent years, the field of developmental biology has undergone a transformative shift with the introduction of stem cell-derived embryo models 1. These innovative models emulate various stages of ...

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

Research from Ph.D. candidate Bohan Chen in the lab of Idse Heemskerk of the Department of Cell and Developmental Biology at the University of Michigan Medical School and their colleagues improves ...

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 quality of oocytes and early embryos is a key determinant of reproductive success. As the primary executors of all cellular functions, proteins orchestrate the molecular events underlying oocyte ...

During embryonic stem cell (ESC) development, pluripotent stem cells transition from a naïve state into a primed state before they take their first steps toward a lineage commitment. Jacob Hanna, a ...

When planning a trip, it's rare that you don't have a choice of route. One may be more direct, another more scenic; but regardless of the time or route taken, the destination is the same. This concept ...

A new study reveals that age-related autophagy decline blocks embryo development by triggering a lipid-burning crisis.

By tracking neural crest cells in catshark embryos, researchers discovered that the molecular toolkit behind face-building is ...
