3D bioprinting improves wound healing by precisely creating scaffolds with living cells and biomaterials, but faces challenges like resolution and speed.

Regenerated hairs can regain their color if the wound occurs during a certain stage of hair growth, and this process is helped by specific skin cells and proteins.

Regenerative cellular therapies show promise for treating non-scarring hair loss but need more research.

Two mutations in KRT74 and EDAR genes cause sheep to have finer wool.

Mesenchymal stem cells show promise for treating various skin conditions and may help regenerate hair.

The nervous system helps control stem cell behavior and immune responses, affecting tissue repair and maintenance.

Researchers successfully grew hair follicle stem cells from mice and humans, which could be useful for tissue engineering and regenerative medicine.

Metabolites and diet affect hair growth cycles in cashmere goats.

Meibomian glands are highly specialized and differ significantly from other sebaceous glands in structure and function.

The mTurq2-Col4a1 mouse model shows how the basement membrane develops in live mammals.

Certain genes are more active during wound healing in axolotl and Acomys, which could help develop materials that improve human wound healing and regeneration.

The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.

Hair and skin healing involve complex cell interactions controlled by specific molecules and pathways, and hair follicle cells can help repair skin wounds.

SOX2 is crucial for skin cell function and hair growth, and it plays a role in skin cancer and wound healing.

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.

A specific group of slow-growing stem cells marked by Thy1 is crucial for skin maintenance and healing in mice.

Skin cell behavior is influenced by the tightness of nearby cells, affecting their growth and development.

Skin cysts might help advance stem cell treatments to repair skin.

Epithelial-mesenchymal interactions control hair growth cycles through specific molecular signals.

Hormones and neuroendocrine factors control hair growth and color, and more research could lead to new hair treatment options.

Men with baldness due to androgenetic alopecia still have hair stem cells, but lack specific cells needed for hair growth.

The protein SLC1A3 is important for activating skin stem cells and is necessary for normal hair and skin growth in mice.

HPV16 oncogenes disrupt the normal activity of hair follicle stem cells.

Adult esophageal cells can start to become like skin cells, with a key pathway influencing this change.

KIF18B is important for correctly positioning cell division machinery in skin cells, affecting hair follicle development.
