The protocol allows easy imaging of dividing cells in C. elegans and can be used for other organisms.

Stem cell differentiation involves gradual chromatin changes and dynamic gene activity.

Hair regeneration needs dynamic cell behavior and mesenchyme presence for stem cell activation.

The conclusion is that the dermal papilla is crucial for hair follicle regrowth, and hair follicles undergo significant structural changes in addition to cell division during regeneration.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

Researchers can now observe live cell processes in the Drosophila midgut for extended periods.

A new method allows detailed tracking of cell regeneration in crustacean legs.

A new method allows detailed, continuous imaging of crustacean leg regeneration without harming the cells.

Small changes in cell division and differentiation can activate blood progenitors.
