Cell-to-cell communication is essential throughout all forms and stages of life, and many communication mechanisms are well studied. However, over the past few years, scientists have found increasing ...

Our skin and mucous membranes are protected by epithelial cells. This 'barrier' tissue performs its function thanks to specialized structures called 'junctions'. They ensure cell cohesion and regulate ...

Epidermal stem cells interact with the extracellular matrix (ECM) to regulate their differentiation and maintain skin architecture. Here, we demonstrate a role for basal epidermal stem cells ...

In pink, wild type cells expressing gamma actin. In black, knock-out cells that do not express gamma actin. The yellowish lines reveal the tortuous nature of the junctions. Our skin and mucous ...
