Human embryo at the 4-cell stage. Cell DNA appears in red and their actin cytoskeleton in blue. The cell on the right has just split its genome into two and is about to divide. In humans, embryonic ...

In his famous letter to the Royal Society dated Oct. 9, 1676, Antonie van Leeuwenhoek described a single-celled eukaryote (Vorticella) and its fascinating ultrafast cell contraction as the first set ...

Experiment with contraction triggered by an optical stimulus of a cell (red) in tissues – results shown with force sensors (top) and then what happens when they are genetically turned off (bottom).

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 ...

Each cardiac muscle cell can have over 5,000 sarcomeres, which compounds both the shortening and relaxation events. "This process appears to be regulated by myosin-binding protein-C (cMyBP-C), which ...
