Zebrafish are useful for studying and developing treatments for human skin diseases.

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.

The document concludes that understanding how adult stem and progenitor cells move is crucial for tissue repair and developing cell therapies.

Stem cells and their surrounding environment in hair follicles work closely together, affecting hair growth and having implications for cancer and tissue regeneration.

Live imaging helps us understand skin immune responses and develop treatments.

Mutant cells in hair follicles are influenced by their location and interactions with surrounding cells.

Two-photon microscopy improves skin imaging but faces safety and cost challenges for clinical use.

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

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.

Intravital imaging helps us better understand stem cells in their natural environment and could improve knowledge of organ regeneration and cancer development.

Proper control of β-catenin activity is crucial for development and preventing diseases like cancer.

Two-photon microscopy effectively tracks live stem cell activity in mouse skin with minimal harm and clear images.

Multiphoton microscopy can effectively image live cells in cornea, skin, and hair follicles over time.
