However, regulated secretion is only one of the numerous exocytic processes that can take place at the cell surface. In addition to the ubiquitous process of constitutive secretion, which requires no ...

One of the most momentous events in the history of life involved endosymbiosis—a process by which one organism engulfed another and, instead of ingesting it, incorporated its DNA and functions into ...

The duplication and inheritance of both the endoplasmic reticulum (ER) and Golgi apparatus is coupled to cell-cycle progression. Although the exact mechanisms underlying ER and Golgi inheritance ...

Plants' ability to sense light and temperature, and their ability to adapt to climate change, hinges on free-forming structures in their cells whose function was, until now, a mystery. Researchers ...

Scientists have made a breakthrough in understanding how different compartments (or organelles) of human cells interact. Organelles are the functional units of a cell. Like organs in a body, they ...

A pioneering study has shed new light on how subcellular organelles divide and multiply. A pioneering study has shed new light on how subcellular organelles divide and multiply. The study, led by ...

Cells use compartments known as organelles to sequester molecules or reactions as a way to control many biochemical processes. Scientists would like to do the same by engineering synthetic organelles ...

More than a decade ago, plant geneticists noticed something peculiar when they looked at grafted plants. Where two plants grew together, the cells of each plant showed signs of having picked up ...

Some organelles are enclosed by membranes, but others are membrane-less, droplet-like clusters of proteins and RNA known as biomolecular condensates. These structures form as needed and act as ...

It was a simple but insightful experiment. At the turn of the 20th century, American biologist Edmund Wilson squashed starfish eggs under a microscope and watched what happened as cellular material ...
