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 ...

A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific molecules from the external environment.

For the study, the researchers aimed to functionalize the cell membrane to enable protein transport across the membrane and assemble them into tissue-like structures afterward. Biological channels ...
