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, ...
New research suggests that exposure to a common “forever chemical” may interfere with the earliest stages of pregnancy. A new animal study suggests that perfluorooctanoic acid (PFOA), a chemical used ...
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 ...
Researchers characterize mechanism for regulating orderly zygotic genome activation in early embryos
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 ...
New stem cell-based embryo model reveals previously unknown communication between early tissues that become the spine and muscles in the central part of the body. From the moment an embryo starts to ...
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 ...
Scientists have developed a new human-based endometrial model to study embryonic implantation in the early stages of ...
