T cells are on the front lines of the immune system, and many reside in the blood and lymph nodes, surveying for and responding to foreign agents and invaders. But special T cells known as gamma delta ...

Epithelial tissues are in constant interaction with their environment. Maintaining their functionality requires dynamic balance (homeostasis) and that their cell numbers are tightly regulated. This is ...

Epithelial conversation An epithelial cell-coated microelectrode array with 60 precisely placed electrodes detects the minute electric signals generated when the cells are injured. (Courtesy: UMass ...

Like a phoenix rising from the ashes, our skin tissue—and in fact many types of epithelial tissue that lines and covers the body's organs—can respond to death and destruction with a burst of ...
