A new view on how tissues flow in the embryo

As embryos develop, tissues flow and reorganize dramatically on timescales as brief as minutes. This reorganization includes epithelial tissues that cover outer surfaces and inner linings of organs and blood vessels. As the ...

Extracellular forces help epithelial cells stick together

Different surfaces and organs of the body are covered by epithelial tissue, which is composed of cells tightly connected to each other. The cells can be attached through junctions that are in direct contact with the cytoskeletal ...

Dental stem cells can generate milk-producing cells

Stem cells of the teeth can contribute to the regeneration of non-dental organs, namely mammary glands. According to a new study from researchers at the University of Zurich, dental epithelial stem cells from mice can generate ...

Putting cells under pressure

As cells divide to form tissues and organs in multicell organisms, they move to where they belong, informed by a series of cues that scientists have yet to observe or fully understand.

Graphene's effects on the lungs

Graphene has been hailed as the material of the future. As yet, however, little is known about whether and how graphene affects our health if it gets into the body. A team of researchers from Empa and the Adolphe Merkle Institute ...
