Senescent skin cells, often referred to as zombie cells because they have outlived their usefulness without ever quite dying, have existed in the human body as a seeming paradox, causing inflammation ...

It's long been assumed that when a parent cell divides into two daughter cells, the parent assumes a spherical shape, which then splits into two cells that have roughly the same, round size. But a new ...

Researchers have found that peroxiredoxins, a family of antioxidant enzymes central to how cells manage oxidative stress, can assemble into a far wider variety of molecular shapes than scientists ...

The cells that make up the walls of the finest of all lymphatic vessels have a lobate, oak leaf-like shape that makes them particularly resilient to changes in fluid volume. A similar cell shape also ...

Until now, cells dividing by mitosis were thought to grow round and then split into two identical, spherical daughter cells. New research has found that some cells are isomorphic, meaning they retain ...

What do cells want to be when they grow up, and how do they get there? Intrigued by these questions, many developmental biologists try to follow the journeys of cells from when they can virtually ...

Cells constantly shift and transform, triggering the complex choreography that shapes living organisms. Whether dividing into new cells or sculpting an embryo, these tiny movements rely on chemical ...

The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...

The symbiotic bacteria that live with reed beetles have different cell shapes in larvae than in adults. This image features these bacteria (in magenta) within the specialized organs of a larva and an ...
