Both main and alternative Wnt signaling are important for regrowing rodent whisker follicles.

Humans have limited regenerative abilities, but new evidence shows the adult brain and heart can regenerate, and future treatments may improve this by mimicking stem cell environments.

The document concludes that while some organisms can regenerate body parts, mammals generally cannot, and cancer progression is complex, involving mutations rather than a strict stem cell hierarchy.

Removing REDD1 in mice increases skin fat by making fat cells larger and more numerous.

New vitamin D3 forms need the vitamin D receptor to reduce fibrosis in human cells.

DPP4-positive fibroblasts play a major role in producing proteins that lead to skin fibrosis.

Fractional photothermolysis helps wounds heal with minimal scarring.

BRG1 is essential for skin cells to move and heal wounds properly.

Fetal scalp cells have more regenerative genes than adult cells, and decellularized muscle matrix is better for muscle repair than commercial alternatives.

Brg1 is crucial for keeping hair follicle stem cells and repairing skin, working with the Sonic Hedgehog pathway to promote hair growth.

The document concludes that understanding hair biology is key to treating hair disorders, with gene therapy showing potential as a future treatment.

Post-finasteride syndrome causes various symptoms in men using finasteride, with no known cure.

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

African spiny mice can regenerate skin, hair, and cartilage, but not muscle, and their unique abilities could be useful for regenerative medicine.

Horizontal scalp biopsy sections effectively diagnose and predict MPAA, with follicular density and inflammation impacting hair regrowth.

Hair regeneration needs dynamic cell behavior and mesenchyme presence for stem cell activation.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

Nerves are crucial for the regeneration of various body parts in many animals.

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.

Researchers created human hair follicles using a new method that could help treat hair loss.

Understanding different types of skin cells, especially fibroblasts, can lead to better treatments for wound healing and less scarring.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

Certain mutations in the H6PD gene cause Cortisone Reductase Deficiency by affecting hormone production.

Larger spheroids improve hair growth, but size doesn't guarantee thicker hair.

The conclusion is that hair growth can be improved by activating hair cycles, changing the surrounding environment, healing wounds to create new hair follicles, and using stem cell technology.

Understanding how hair follicle stem cells work can help find new ways to prevent hair loss and promote hair growth.

Photothermal hydrogels are promising for infection control and tissue repair, and combining them with other treatments could improve results and lower costs.

Activating β-catenin in different skin stem cells causes various types of hair growth and skin tumors.

Wnt10b helps blood stem cells grow after injury.

The study found that bioengineered hair follicles work when using cells from the same species but have issues when combining human and mouse cells.
