Modern cells are complex chemical entities with cytoskeletons, finely regulated internal and external molecules, and genetic material that determines nearly every aspect of their functioning. This ...

Cell membranes are the boundaries of living cells. They are made up of amphiphilic lipids, cholesterol, and membrane proteins arranged in a dynamic bilayer. They regulate signal transduction, ...

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular processes can create voltage spikes similar to those used by neurons. These ...

Artificial cells created in the laboratory offer a wide range of potential applications. Until now, however, their membranes—unlike those of real cells—have been virtually impermeable. Researchers at ...

Tubular membrane protrusions — filopodia, tunneling nanotubes, retraction fibers — are ubiquitous structures on the cell ...

Membrane compartments (vesicles) were prepared from two phospholipids with distinct acyl-chain structures, each encapsulating a different DNA species. Upon repeated freeze–thaw (F/T) cycles, the ...
