Bone-marrow and epidermal stem cells help heal wounds differently, with bone-marrow cells aiding in blood vessel formation and epidermal cells in hair growth.

Aging causes changes in the scalp that can affect hair growth and lead to older-looking hair in women.

The Foxn1(-/-) nude mouse shows disrupted and expanded skin stem cell areas due to high Lhx2 levels.

Dermal papilla cells help wounds heal better and can potentially grow new hair.

Androgens increase growth factors in skin cells, which may lead to acne.

The dermal papilla is crucial for hair growth and health, and understanding it could lead to new hair loss treatments.

Androgen receptor activity blocks Wnt/β-catenin signaling, affecting hair growth and skin cell balance.

Tight junctions are key for skin protection and controlling what gets absorbed or passes through the skin.

Platelet-rich plasma can help grow more mouse hair follicles, but it doesn't work for human hair follicles yet.

Mouse cell exosomes help hair regrowth and wound healing by activating a specific signaling pathway.

MIM is crucial for hair follicle formation and regeneration by controlling cilia formation and hedgehog signaling through its interaction with Cortactin and Src.

Different genes and pathways are active in yak skin and hair cells, affecting hair growth and immune responses.

Epidermal stem cells help heal severe skin wounds and have potential for medical treatments.

A new hydrogel made from human cells improves wound healing by working with immune cells to promote repair.

Scientists have found a way to create hair follicles from skin cells of newborn mice, which can grow and cycle naturally when injected into adult mouse skin.

The flap assay grows the most natural hair but takes the longest, the chamber assay is hard work but gives dense, normal hair, and the patch assay is quick but creates poorly oriented hair with some issues.

Only skin melanocytes, not other types, can color hair in mice.

Thyroid hormone may be useful for treating various skin conditions and needs more research.

Skin and hair can regenerate after injury due to changes in gene activity, with potential links to how cancer spreads. Future research should focus on how new hair follicles form and the processes that trigger their creation.

Thyroid hormones affect skin texture, hair and nail growth, and can cause skin diseases related to thyroid problems.

ILK is essential for proper hair follicle development and structure.

Stem cells can rejuvenate skin, restore hair, and aid in wound healing.

Using stem cells from fat tissue can significantly improve wound healing in dogs.

New cell-based therapies may improve hair loss treatments in the future.

Age, gender, and hair loss affect scalp characteristics differently in young Caucasian adults.

Activin A is important for creating new hair follicles.

Skin fat has important roles in hair growth, skin repair, immune defense, and aging, and could be targeted for skin and hair treatments.

The patch assay can create mature hair follicles from human cells and may help in hair loss treatments.

3D scaffolds mimicking the extracellular matrix are crucial for effective hair follicle regeneration.

New microspheres help heal skin wounds and regrow hair without scarring.
