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.

The review found that different stem cell types in the skin are crucial for repair and could help treat skin diseases and cancer.

The current understanding of frontal fibrosing alopecia involves immune, genetic, hormonal factors, and possibly environmental triggers, but more research is needed for effective treatments.

Human stem cells were turned into cells similar to those that help grow hair and showed potential for hair follicle formation.

Scientists can now create skin with hair by reprogramming cells in wounds.

Glycyrrhizic acid and licorice extract can significantly reduce unwanted hair growth.

Wnt1a-conditioned medium from stem cells helps activate cells important for hair growth and can promote hair regrowth.

Cell-based therapies show promise for treating Limbal Stem Cell Deficiency but need more research.

The shape of fibrous scaffolds can improve how stem cells help heal skin.

Pro-IGF-II improves muscle repair in old mice.

Exosomes are important for skin health and could help diagnose and treat skin diseases.

PBX1 reduces aging and cell death in stem cells by boosting SIRT1 and lowering PARP1.

Melanoma development can be linked to the breakdown of skin's melanin-producing units.

New treatments for vitiligo may focus on protecting melanocyte stem cells from stress and targeting specific pathways involved in the condition.

Activating Wnt in skin cells controls the number of hair follicles by directing cell movement and fate.

Removing Lrig1-positive stem cells in mice causes temporary loss of sebaceous glands.

Thymosin β4 promotes hair growth by activating stem cells in hair follicles.

Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.

STAT5 activation is crucial for starting the hair growth phase.

Rat whisker cells can help turn other cells into nerve cells and might be used to treat brain injuries or diseases.

The hair follicle dermal sheath is essential for hair shedding and needs to communicate with the outer root sheath for normal hair growth cycles.

Wounds can cause new hair growth in adult mice, influenced by Wnt signaling.

The skin has different types of stem cells that can repair and regenerate tissue.

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

Advancements in creating skin grafts with biomaterials and stem cells are promising, but more research is needed for clinical application.

Platelet-rich plasma (PRP) is a simple, cost-effective treatment that promotes hair growth and reduces hair loss, with high patient satisfaction.

MSCs and their exosomes may speed up skin wound healing but need more research for consistent use.

Using bioreactors, scientists can grow more skin stem cells that keep their ability to regenerate skin and hair.

Hair is important for protection, social interaction, and temperature control, and is made of a growth cycle-influenced follicle and a complex shaft.

Innate immunity genes in hair follicle stem cells might have new roles beyond traditional immune functions.
