Cells move as concentration shifts

What do wound healing, cancer metastasis, and bacteria colonies have in common? They all involve the collective displacement of biological cells. New research sheds some new light on the physical mechanisms provoking the ...

It smells fishy: Copper prevents fish from avoiding danger

Fish fail to detect danger in copper-polluted water. A new study, to be presented at the meeting of the Society for Experimental Biology on the 5th of July, shows that fish cannot smell a danger odor signal emitted by other ...

Finding Nematostella: An ancient sea creature

A study of tentacle-formation in a sea anemone shows how epithelial cells form elongated structures and puts the spotlight on a new model organism.

Flexible adult stem cells, right there in your eye

In the future, patients in need of perfectly matched neural stem cells may not need to look any further than their own eyes. Researchers reporting in the January issue of Cell Stem Cell, a Cell Press publication, have identified ...

How cells know when to tighten the belt

The epithelial cells that line the surface of tissues form a tightly sealed barrier, with individual cells joined together by structures called apical junctional complexes (AJCs). However, embryonic epithelium undergoes multiple ...

Light can detect pre-cancerous colon cells

After demonstrating that light accurately detected pre-cancerous cells in the lining of the esophagus, Duke University bioengineers turned their technology to the colon and have achieved similar results in a series of preliminary ...

Researchers report progress using iPS cells to reverse blindness

Researchers have used cutting-edge stem cell technology to correct a genetic defect present in a rare blinding disorder, another step on a promising path that may one day lead to therapies to reverse blindness caused by common ...

The self-made eye: Formation of optic cup from ES cells

Groundbreaking research from the RIKEN Center for Developmental Biology (CDB) shows how mouse stem cells spontaneously form into optic cups, the precursors of eyes. A report on this research, published this week in Nature, ...
