Scientists know that cells in all higher organisms cells need to bind to each other for the development, architecture, maintenance and function of tissues. Mysteries have remained, however, about exactly how cells manage this feat. Scientists from the Florida campus of The Scripps Research Institute (TSRI) have now solved part of this puzzle by defining the structure of a protein known as α-catenin, which is essential to this process. The work was published online ahead of...

New research explains how cells regulate their bonds during the development of new blood vessels. For the first time, the role of the protein Raf-1 in determining the strength of the bond between cells has been shown. If Raf-1 is not present, the cells cannot stick together and the formation of new blood vessels is inhibited. This discovery may one day lead to new approaches to cancer treatment. Angiogenic sprouting, the process by which new blood vessels grow from existing vessels, is a...

In biology, the key to a healthy life is organization. Cells that properly organize themselves into communities live long and prosper, whereas disorganized cells can become cancerous. A study by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) of the different types of cells that make up the human breast  shows that not only do cells possess an innate ability to self-organize into communities, but these communities of different types of cells can also organize...

University of Pennsylvania bioengineers have demonstrated that the cells that line blood vessels respond to mechanical forces "” the microscopic tugging and pulling on cellular structures "” by reinforcing and growing their connections, thus creating stronger adhesive interactions between neighboring cells. Adherens junctions, the structures that allow cohesion between cells in a tissue, appear to be modulated by endothelial cell-to-cell tugging forces.  Both the size of...
