Vitamin D receptor is crucial for starting hair growth after birth.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

FoxN1 gene is essential for proper thymus structure and preventing hair loss.

Blocking a specific protein signal can make hair grow on mouse nipples.

The KRTAP11-1 gene promoter is crucial for specific expression in sheep wool cortex.

Using neurohormones to control keratin can lead to new skin disease treatments.

Vitamin D receptor can control the hairless gene linked to hair loss even without vitamin D.

Rac1 is essential for proper hair structure and color.

A pathway helps maintain long telomeres in both stem and cancer cells.

Regulatory T cells are essential for normal and improved wound healing in mice.

A TP63 gene mutation causes significant hair loss and mild skin, nail, and tooth abnormalities.

Tcf3 helps cells move and heal wounds by controlling lipocalin 2.

FoxN1 overexpression in young mice harms immune cell and skin development.

Certain proteins help nerve cells branch, and other findings relate to cancer, stem cell behavior, and cell division.

The tumor suppressor BRCA2 helps in cell division by bringing key proteins to the area where cells split.

Hair grows when stem cell offspring in the follicle base proliferate, influenced by the dermal papilla.

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

Overexpression of activin A in mice skin causes skin thickening, fibrosis, and improved wound healing.

Autophagy is crucial for normal sebaceous gland function and sebum composition.

Mice genetically modified to produce more Del1 protein had faster hair regrowth.

Dermagraft and Dermalogen had a lot of granulation, while Alloderm, Integra, and ADM had good blood vessel growth for skin healing.

Mice treatments didn't grow hair, a patient treatment may affect immune response, and people with hair loss often feel anxious or depressed.

Smad-4 and Smad-7 are key in hair follicle development, with other Smads being less important.

Parathyroid hormone-related protein helps control hair growth phases in mice.

Glutamine metabolism affects hair stem cell maintenance and their ability to change back to stem cells.

Chemotherapy causes hair loss by damaging hair follicles and stem cells, with more research needed for prevention and treatment.

Sox2-positive dermal papilla cells have unique characteristics and contribute more to skin and hair follicle formation than Sox2-negative cells.

Hair and skin can regenerate without bulge stem cells due to other compensating cells.

The mesenchyme can start hair growth, but the exact signal that causes this is still unknown.
