Over 130 mammal species can delay embryonic development, giving their offspring the best possible chance of survival in ideal ...

Then researchers placed blastoids and embryos donated after infertility treatments inside the little device and watched it ...

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ago, when viruses inserted their genetic material into our ancestors' ...

Under the microscope, MSK scientists studied how cells in a mouse embryo (green) move out and break away from their original tissue by contracting their surfaces (red). Studying this process, known as ...

High-resolution 3D womb model gives insights into embryo implantation, infertility, and signals between embryo and mother, ...

Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the ...

Researchers have gained new insights into the mechanism behind the spatial organization of DNA within the cells of early embryos. When an embryo is first formed after fertilization, each cell has the ...

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and ...

Neal D. Amin is in the Department of Psychiatry and Behavioral Sciences, Stanford University, Stanford, California 94305, USA, and in the Stanford Brain Organogenesis Program, Wu Tsai Neurosciences ...

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 ...
