Hair loss reduces hair thickness and coverage, but drug treatments mainly revive dormant hairs rather than reverse thinning; patients often undervalue their hair loss severity.

High levels of ERK activity are key for tissue regeneration in spiny mice, and activating ERK can potentially redirect scar-forming healing towards regenerative healing in mammals.

External factors can cause skin cancer cells that usually don't spread to grow and form tumors in mice.

Telomerase-positive cells are mainly in the bulb matrix and outer root sheath of hair follicles.

Men with lower 2nd to 4th finger ratios tend to have larger sinus volumes.

Dermal fibroblasts have adjustable roles in wound healing, with specific cells promoting regeneration or scar formation.

Certain immune cells in the skin release a protein that stops hair growth by keeping hair stem cells inactive.

Targeting TGFβ can improve skin immunity in older people.

Scientists found a specific group of itch-sensing nerve cells in mice important for feeling itch but not for sensing heat or touch.

Large-scale fibronectin nanofibers help heal wounds and repair tissue in a skin model of a mouse.

GALT5 and GALT2 are important for plant growth and development because they help with protein glycosylation.

Sostdc1 controls the size and number of hair and mammary gland structures.

Progerin affects cell shape but not hair or skin in mice.

Neural crest-derived progenitor cells in the cornea could help treat corneal issues without transplants.

Overactivating Hedgehog signaling makes hair follicle cells in mice grow hair faster and create more follicles.

Hair thinning causes stem cell loss through a process involving Piezo1, calcium, and TNF-α.

Researchers created a rat model to study skin damage caused by radiation, which could help develop new treatments.

Activating Nrf2 in skin cells speeds up wound healing by increasing the growth of certain stem cells.

Using a drug to activate bone marrow stem cells can help the liver regenerate and function better after major surgery in rats.

Alpinetin helps grow hair by turning on hair stem cells and is safe for use.

A specific group of skin stem cells was found to help maintain hair follicle cells.

Skin-derived stem cells grow faster and are easier to obtain than hair follicle stem cells, but both can become various cell types.

Palmitoyl-GDPH speeds up wound healing and improves tissue regeneration without toxicity.

GDNF helps grow hair and heal skin wounds by acting on hair stem cells.

The gel with icariin speeds up wound healing, reduces scarring, and helps hair growth by controlling BMP4 signaling. It also reduces inflammation and improves wound quality in mice, adapts to different wound shapes, and gradually releases icariin to aid healing. It also prevents too much collagen and myofibroblast formation during skin healing.

The local environment is crucial for cell development in the tongue.

Chick embryo extract helps rat hair follicle stem cells potentially turn into Schwann cells, important for the nervous system.

Hedgehog signaling in certain cells is crucial for hair growth during wound healing.

A specific genetic change is linked to mental disorders, intellectual disability, and possibly autoimmune disease in a family.

Special particles from umbilical cord stem cells help heal skin wounds in diabetic mice by preventing certain immune cell death.
