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.

Targeting regulatory T cells may help treat age-related diseases.

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

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

Male pattern baldness involves hormone-related hair thinning, shorter hair, and inflammation.

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

AGA causes hair loss through follicle miniaturization and hair cycle changes; regrowth depends on anagen initiation in kenogen follicles.

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

The study showed that some hair follicle stem cells wake up to grow hair while others stay asleep, and that the environment around them is important for hair growth.

Fetal skin has unique immune cells different from adult skin.

HT-scCAT-seq helps understand gene regulation in embryonic skin development.

A specific mutation in Kras causes abnormal tissue changes by making a cell signal continuously active, which disrupts normal cell coordination.

Hair growth and shedding involve specific cell changes and gene roles.

Scientists have improved 3D models of human skin for research and medical uses, but still face challenges in perfectly replicating real skin.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

Lower MC2R expression may contribute to alopecia areata.

The research maps the complex development of early mouse skin, identifying diverse cell types and their roles in forming skin layers and structures.

Chinese herbal medicine can help treat hair loss by promoting hair growth and preventing cell death, maintaining a balance between hair growth and loss.

The new hydrogel dressing improves wound healing with strong antibacterial effects and better mechanical strength.

Activating autophagy might reverse skin fibrosis.

The skin's dermal layer contains true stem cells with diverse functions and interactions that need more research to fully understand.

The hydrogel helps heal diabetic wounds by combining antibacterial, antioxidant, and immune-boosting effects.

STIM1 is essential for sweat secretion.

Goat skin has collagen, elastic, and reticular fibers, with hair follicles increasing in depth as goats age.

Fibre optic confocal imaging can visualize skin layers, blood vessels, and nerves in live mice.

Sequential immunotherapy can effectively treat alopecia areata by managing inflammation and promoting hair regrowth.

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

3D bioprinting is advancing in plastic and reconstructive surgery, especially for creating tissues and improving surgical planning, but faces challenges like vascularization and material development.

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.
