Development of embryos "We found that the randomness in when and how cells divide actually helps embryos to develop properly," says Dimitri Fabrèges, a postdoc researcher in the Hiiragi group. He and ...

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

In vertebrates, the skeleton of different regions of the body arises from different precursor cells. Researchers at the University of Basel have now discovered that these skeletal cells do not just ...

Only two weeks after fertilization, the first sign of the formation of the three axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear. At this stage, known as ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

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, ...

Growth plates are areas of cartilage found at the ends of long bones. They play a role in the bone growth of children and teens. An injury to a growth plate can affect the development of a bone. While ...
