In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

Early development of an embryo is solely supported by maternally deposited RNAs and proteins until its own genome is activated through a process called zygotic genome activation (ZGA). Recent research ...

The architecture of the body is not encoded as a formal blueprint; rather, it's the tightly orchestrated activation and ...

Over half of our genomes consists of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the "dark side" of the ...

The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...

A new study shows that the embryo and the uterine lining conduct an active "conversation" from the very earliest stages of implantation. They engage in a back and forth of tiny packages called ...

Researchers at the Center for Embryology and Healthy Development (CRESCO) aim to find out why so many early embryos fail in their development. New insights into how maternal and paternal DNA is ...

Natural ovulation before frozen embryo transfer is as effective as hormone treatment for achieving a healthy baby by vitro ...
