Advanced therapies like gene, cell, and tissue engineering show promise for hair regrowth in alopecia, but their safety and effectiveness need more verification.

Immune cells are crucial for hair growth and preventing hair loss.

Scientists created a lab-grown hair follicle model that behaves like real hair and could improve hair loss treatment research.

Deleting Smad4 and PTEN genes in mice causes rapid, invasive forestomach cancer.

Deleting Smad4 and PTEN genes in mice causes rapid, invasive stomach cancer.

Different fish use the same genes to regrow teeth.

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

Male hormones are important for hair and oil gland development and can cause conditions like excessive hair growth and acne.

ARHGEF3 is essential for proper hair follicle development.

Secretome-based therapies could improve hair growth better than current treatments.

Stromal stem cells may help heal wounds by becoming structural cells or affecting the immune system, but more research is needed to understand how.

Estrogen Receptor ß (ERß) is the main hormone controller in human skin and hair follicles, not Estrogen Receptor α (ERα) or the Androgen Receptor (AR).

Research on epidermal stem cells has advanced significantly, showing promise for improved clinical therapies.

Hair in mammals likely evolved from glandular structures, not scales.

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

Keratin injections can promote hair growth by affecting hair-forming cells and tissue development.

Deep skin fibroblasts help recruit immune cells for better wound healing.

Using developmental signaling pathways could improve adult wound healing by mimicking scarless embryonic healing.

Sporadic trichoblastic neoplasms generally don't recur or spread, with one case showing a specific genetic fusion.

Hair loss patterns differ between males and females due to 5 master regulators and JAK-STAT signaling affects hair growth.

Fully regenerating human hair follicles not yet achieved.

Procyanidin B-2 from apple juice significantly increases hair growth and may be more effective than minoxidil without side effects.

TNF family proteins are crucial for the development of skin features like hair, teeth, and mammary glands.

Keratin 15 is not a reliable sole marker for identifying epidermal stem cells because it's found in various cell types.

Lizards can regrow their tails, and studying this process helps understand scar-free healing and limb regeneration.

Adult stem cells are important for tissue repair and have therapeutic potential, but more research is needed to fully use them.

Proper control of β-catenin activity is crucial for development and preventing diseases like cancer.

The WNT signaling pathway is crucial for mesenchymal stem cells' function and therapy success.

Calcium signals and SHH guide the direction of feather growth in chicken skin.

Macrophages are more involved in Lichen planopilaris than in Frontal fibrosing alopecia.
