Gap junctions are specialised intercellular channels that facilitate direct communication between adjacent cells by allowing the regulated exchange of ions, second messengers and small metabolites.

Most current photosynthesis models, and interpretations of many whole-leaf CO2 gas exchange measurements, are based on the often unstated assumption that the partial pressure of CO2 is nearly uniform ...

Within multicellular organisms, cells build connections with each other forming cell layers that cover the surfaces of tissues and organs and separate structures in the body. For example, the skin ...

Scientists found that messenger RNA (mRNA) molecules that carry genetic instructions to the far reaches of neurons in the brain tend to cluster together mostly because they are abundant, not because ...

Elevation of the calcium concentration in human keratinocyte culture rapidly induces the redistribution of E-cadherin, P-cadherin, vinculin, β1 integrin, and desmoplakin to the cell-cell borders.

Now, MIT engineers have found that this "intercellular" fluid plays a major role in how tissues respond when squeezed, pressed, or physically deformed. Their findings could help scientists understand ...

Developmental biologists have discovered that during egg development in fruit flies, intercellular gaps open between epithelial cells in a controlled way at the points where three cells meet. This ...
