Transport of molecules within a cell and out of the cell requires a complex endomembrane system. Endocytosis occurs when the cell membrane engulfs particles (dark blue) outside the cell ...

The ability to maintain concentration gradients and sometimes move materials against them is vital to cell health and maintenance. Thanks to membrane barriers and transport proteins, the cell can ...

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

A recent study published in Engineering presents an innovative acoustofluidics-based approach for intracellular nanoparticle ...

Targeted therapy uses microbubbles to transport medication directly to its destination.

Transport across membranes All cells are enclosed by a cell membrane, which is selectively permeable. Molecules can move into or out of cells by diffusion and active transport. Cells can gain or ...

While chemical signals such as morphogens have been known for a long time, fluid transport has recently emerged as another potential way to globally organize cell behavior during morphogenesis (Navis ...

In an article published in the journal Trends in Biochemical Sciences, Alicia Kowaltowski, full professor at the University of São Paulo's Institute of Chemistry (IQ-USP) in Brazil, advocates the ...

Similar to a small cut that heals itself after a short time, individual cells in our body suffer "wounds" in their protective layer, the cell membrane, every day and have to repair them again.

the pores close and seal off the transport pathway. This control over membrane permeability is a major step forward in creating artificial cells that can selectively regulate molecular transport.
