It's no small feat to create a spinal column. In humans, 33 interlocking bones must come together to protect the spinal cord. These vertebrae are interconnected and have delicate attachments to ...

Pregnant women rely on a balanced diet and supplements to deliver proper nutrients to their babies, to ensure they grow healthfully. Such nutrients contribute to fueling development and providing ...

One of the most dramatic phases of fetal development occurs as previously unstructured collections of rapidly dividing precursor cells begin forming the embryo's spine. When this process goes well, it ...

In humans, pregnancy lasts around nine months. In mice, only 20 days, and in rhinoceroses, as long as 17 months. Although many mammalian species go through the same stages during embryo development, ...

Segmentation of the vertebrate body is first established during embryogenesis by the periodic formation of pairs of somites — for example, every 120 minutes in mouse, 90 minutes in chicken and 30 ...

After decades of effort, scientists use induced pluripotent stem cells to model human spine development. Findings provide proof of existence of a segmentation clock in humans guiding spine formation.

Researchers used iPS cells to reconstructed the human 'segmentation clock,' a key point in early embryonic development that determines how the body gets segmented. The 'segmentation clock' is a ...
