The determining factors of cell shape examined

A European team is investigating the role of the bacterial cell wall and the cytoskeleton in mediating cell shape. Results are expected to have broader implications for cell biology.

Research explores road signs on the intracellular highway

The interior of every cell within our bodies is crisscrossed with a network of molecular highways upon which nutrients, replacement parts, and other vital materials travel to their appropriate location. The system is immensely ...

Human white blood cells use molecular paddles to swim

Human white blood cells, known as leukocytes, swim using a newly described mechanism called molecular paddling, researchers report in the September 15th issue of Biophysical Journal. This microswimming mechanism could explain ...

Study yields insights into how plant cells grow

A study by Purdue University plant scientists and University of Nebraska-Lincoln engineers advances our understanding of how plants control their shape and development at the cellular level.

Lace plants explain programmed cell death

Programmed cell death (PCD) is a highly regulated process that occurs in all animals and plants as part of normal development and in response to the environment. New research published in BioMed Central's open access journal ...

Biochemists zero in on key molecules that enable cells to crawl

Biochemists have made a discovery that sheds light on the molecular machinery that allows some cells, such as immune cells or even malignant cancer cells in humans, to wiggle their way through tissues like organs, skin or ...

Team charts new understanding of actin filament growth in cells

University of Oregon biochemists have determined how tiny synthetic molecules disrupt an important actin-related molecular machine in cells in one study and, in a second one, the crystal structure of that machine when bound ...

Cells on the move

Cells on the move reach forward with lamellipodia and filopodia, cytoplasmic sheets and rods supported by branched networks or tight bundles of actin filaments. Cells without functional lamellipodia are still highly motile ...
