microtubules

Researchers explore the idea that molecular patterns in individual cells could underlie the development of a left and a right in animals.

Researchers use imaging to show how actin fibers tilt and then swirl to create left-right asymmetry in the cell.

Microtubules need actin to disassemble focal adhesions, allowing for cell movement.

By combining two microscopy techniques, researchers produce images of structures less than 10 nanometers wide.

Presentations at the Society for Neuroscience meeting point to changes in neurons and connectivity between brain regions as potential components of the enigmatic condition.

To chew up waste in far-reaching dendritic spines, lysosomes are trafficked sometimes hundreds of microns away from the cell bodies of neurons in rats.

Her doctoral advisor told her to amuse herself, and Fiona Watt has done just that—probing individual stem cells and determining the genes and molecules that direct them to differentiate or cause them to contribute to cancer.
