Most cell structures are not visible to the naked eye without using stains for visualization. The stains used in these images highlight how cell biologists use tricks to “see the invisible.” Invite ...

Researchers discover that actin acts in the cell nucleus and is partly responsible for the expression of male sexual characteristics. Steroid hormones, to which belong sex hormones like estrogen or ...

The cytoskeleton is a cellular scaffolding system whose functions include maintenance of cellular shape, enabling cellular migration, division, intracellular transport, signaling and membrane ...

In the 1950s, advances in microscopy techniques allowed scientists to visualize synaptic communication between two brain cells for the first time. 1,2 However, many details beyond the general synapse ...

Some cells, such as immune cells, are highly mobile—they constantly remodel their shape, migrate toward a wound that needs to ...

Researchers have discovered that septins -- a part of the cytoskeleton -- form a barrier to the penetration of Pseudomonas aeruginosa. The process is dependent on the LecA molecule on the surface of ...

Prior to using this narrative, have learners create their own model of a cell in their notebooks using whatever background information or experience they might have. While exploring the narrative, ...

Plants are sessile organisms and are therefore exposed to damages caused by the predictable increase in temperature. We have analyzed the effects of temperatures on the development of pollen tubes by ...

Scientists at Feinberg are reshaping scientific understanding of the cell's tiniest components—structures once thought to be static, now revealed to be dynamic engines of cellular life. As they probe ...

Surrounded by nutrients and undetected by the immune system, the interior of a cell is the ideal place for pathogenic bacteria to reproduce. Nevertheless, it was long thought that they existed outside ...
