Cells in humans and all vertebrates are tightly packed together to form organs and glands — tissues essential for living, breathing and moving. The narrow spaces between cells represent natural weak ...
Barriers between stem cells play a crucial role in human development—and offer a new potential route for fertility treatment SAN FRANCISCO, CA—As a human embryo grows, a set of molecules directs cells ...
Our bodies and organs are shielded from the external environment by tissue barriers like the skin. These barriers must be tightly sealed to prevent unwanted substances from entering. This sealing is ...
The formation of tight junctions by parietal epithelial cells (PECs) creates a barrier that confines proteins to the Bowman's space, say the researchers of a new study. Disruption of these tight ...
Cell-to-cell junctions were visualized by ZO1-GFP, and the dynamics of cell junctions were captured by movies. When the cells indicated by * were spontaneously stretched, a continuous belt of cell ...
