Cellular clock regulating human spine development

More than 20 years ago, the lab of developmental biologist Olivier Pourquié discovered a sort of cellular clock in chicken embryos where each "tick" stimulates the formation of a structure called a somite that ultimately ...

Protein dynamics in the beating heart

The protein titin is a large structural component of the sarcomere—the machinery that mediates contraction of cardiac muscle cells. Despite its importance to the beating heart, little is known about titin turnover.
