These time-lapse images show microtubules labeled with green fluorescence protein in a living wild-type cell of the fungus Neurospora crassa. The images were obtained by total internal reflection fluorescence microscopy.

Microtubules typically have one end attached to a microtubule-organizing center, the centrosome. The other end extends into the cytoplasm, which undergoes a balanced stochastic cycling between self-assembly and disassembly at the cell cortex.

The image is part of a collection created by ASU cell biologist Robert Roberson. The collection has appeared in multiple galleries throughout the Phoenix area. Read more about Roberson's microscope art in "The art of life."
