Memory T cells in the skin balance staying put and moving into the blood, clustering around hair follicles, and increasing in number after infection.

Feather growth and regeneration involve complex patterns, stem cells, and evolutionary insights.

New methods have greatly improved our understanding of stem cell behavior and roles in the body.

Compartmentalized organization might be crucial for stem cells to effectively respond to growth or injury.

Keratin 79 marks a new group of cells that are key for creating and repairing the hair follicle's structure.

New cells are added to the hair's dermal papilla during the active growth phase.

Live imaging has advanced our understanding of stem cell behavior and raised new research questions.

Some stem cells in the body rarely divide, which could help create better treatments for diseases and aging.

Cholesterol balance is important for hair health, and problems with it can lead to hair loss conditions.

Poplar seed hairs grow from the placenta at the ovary base, with endoreduplication playing a key role in their development, and share similar cellulose synthesis processes with cotton fibers.

Certain cells outside the hair follicle's bulge area can quickly regenerate damaged hair follicles, potentially helping to reduce hair loss from cancer treatments.

The article concludes that hair loss is a common side effect of drugs treating skin cancer by blocking the hedgehog pathway, but treatment should continue, and more selective drugs might prevent this side effect.

In vivo lineage labelling is better than in vitro methods for identifying and understanding stem cells.

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

Mouse spermatogenesis shows that stem cells can behave flexibly and move widely in open environments.

New techniques have enhanced our understanding of how stem cells function and the role of mutations in aging tissues, which may influence future cancer therapies.

The research identified genes that explain why some sheep have curly wool and others have straight wool.

The research reveals how early embryonic mouse skin develops from simple to complex structures, identifying various cell types and their roles in this process.

Dermal papilla cells are key for hair growth and color, influencing hair type and size, and their interaction with stem cells could help treat hair loss and color disorders.

Testosterone can both promote hair growth and cause baldness by affecting hair growth signals.

CD4 is crucial for maintaining skin stem cell balance and aiding wound healing.

Hdac1 and Hdac2 help maintain and protect the cells that control hair growth.
