Recent advances in cellular biology have underscored the central role of the actin cytoskeleton in the regulation of oocyte maturation and fertilisation. Actin filament rearrangements not only ...

Researchers found that attractant peptides released by female tissues initiate rapid depolymerization and repolymerization of actin at the leading edge of the pollen tube tip, steering its direction ...

Living cells are highly organized, yet they are not assembled using rigid blueprints or by following a predetermined plan.

A buildup of a structural protein called F-actin inside aging brain cells appears to cripple the cellular waste-clearing machinery that keeps neurons healthy, according to a study in Drosophila fruit ...

An electron microscopy study revealed key details of actin filaments, which are essential structural elements of cells and muscles. Actin filaments -- protein structures critical to living movement ...

Biophysicists have gained a new insight about the dynamics of cellular movement, which is key to processes ranging from stem-cell differentiation and wound healing to the development of diseases such ...

Living cells are highly organized, yet they are not assembled using rigid blueprints or by following a predetermined plan. Instead, order emerges on ...

Humans and fruit flies both may become forgetful as they age. But because fruit flies have a lifespan of only about two months, they can be a useful model for understanding the cognitive decline that ...

Cells in the human body are made to move. They assemble during embryo development, migrate to repair tissue, hunt pathogens, and perform a host of other tasks requiring travel. As part of the ...
