Fibroblasts invade at a snail's pace
A transcription factor known to drive the formation of fibroblasts during development also promotes their ability to invade and remodel surrounding tissues, report Rowe et al. in the February 9, 2009 issue ...

Biophysics: Order in chaos
The process of skeletal muscle contraction is based around protein filaments sliding inside sarcomeres — the structural units of muscle fiber. Inside each sarcomere is a set of filament motors, which ...

In lab, Pannexin1 restores tight binding of cells that is lost in cancer
First there is the tumor and then there's the horrible question of whether the cancerous cells will spread. Scientists increasingly believe that the structural properties of the tumor itself, such as how tightly ...

Human cells build protein cages to trap invading Shigella
In research on the never-ending war between pathogen and host, scientists at the Pasteur Institute in Paris have discovered a novel defensive weapon, a cytoskeletal protein called septin, that humans cells deploy to cage ...

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 ...

Oocytes: Going with the flow
Most cells rely on structural tethers to position chromosomes in preparation for cell division. Not so oocytes. Instead, a powerful intracellular stream pushes chromosomes far-off the center in preparation ...

The forces of attraction: How cells change direction
Many cell types in higher organisms are capable of implementing directed motion in response to the presence of certain chemical attractants in their vicinity. A team led by Dr. Doris Heinrich of the Faculty of Physics and ...

How muscle develops: A dance of cellular skeletons
Revealing another part of the story of muscle development, Johns Hopkins researchers have shown how the cytoskeleton from one muscle cell builds finger-like projections that invade into another muscle cell's territory, eventually ...

Nano-motor with a light switch: Light-triggered myosin allows real-time study of cells
(PhysOrg.com) -- Molecular "motors" are at the root of most biological movement. They propel cell components, whole cells, and even our muscles on command. Barbara Imperiali and a team from the Massachusetts ...

How molecules get to the right place at the right time
Active transport processes in cells ensure that proteins with specialized local functions reach their intracellular destinations. Impaired transport causes cellular dysfunction or even cell death. Scientists from Ludwig-Maximilians-Universitaet ...

Cell 'glue' opens new pathways to understanding cancer
Australian researchers have found a novel way in which the proteins that 'glue' cells together to form healthy tissues can come unstuck, opening new avenues to understanding how these proteins are disturbed in diseases such ...
