Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into collagen designed to mimic uterine tissue —a key stage in reproduction. The ...

A new finding clarifies how certain proteins work together to direct cells to either specialize or remain pluripotent. This image, generated in the lab of developmental biologist Anna-Katerina (Kat) ...

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 ...

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 ...

For the first time ever, researchers have captured a human embryo implanting in real-time, revealing new details about the surprisingly strong mechanical forces this little bundle of cells uses to ...
