Motile cells have developed a variety of migration modes relying on diverse traction-force-
generation mechanisms. Before the behavior of intracellular components could be easily …

This paper summarizes the recent advances in image processing methods for
morphological cell analysis. The topic of morphological analysis has received much …

Cells have an internal compass that enables them to move along shallow chemical
gradients. As amoeboid cells migrate, signaling events such as Ras and PI3K activation …

We observe and quantify wave-like characteristics of amoeboid migration. Using the
amoeba Dictyostelium discoideum, a model system for the study of chemotaxis, we …

Accurate decoding of spatial chemical landscapes is critical for many cell functions.
Eukaryotic cells decode local chemical gradients to orient growth or movement in productive …

Myosin II is a central mechanoenzyme in a wide range of cellular morphogenic processes.
Its cellular localization is dependent not only on signal transduction pathways, but also on …

Chemotaxis involves the coordinated action of separable but interrelated processes: motility,
gradient sensing, and polarization. We have hypothesized that these are mediated by …

The behaviour of an organism often reflects a strategy for coping with its environment. Such
behaviour in higher organisms can often be reduced to a few stereotyped modes of …

Pavement cells (PCs) are the most frequently occurring cell type in the leaf epidermis and
play important roles in leaf growth and function. In many plant species, PCs form highly …

Plasmodesmata (PD) form tubular connections that function as intercellular communication
channels. They are essential for transporting nutrients and for coordinating development …
