Bioengineered salivary glands in mice can produce saliva when tasting sour or bitter, but have different protein levels and nerve signals compared to natural glands.

Deleting the CRIF1 gene in mice disrupts skin and hair formation, certain proteins affect hair growth, a new compound may improve skin and hair health, blood cell-derived stem cells can create skin-like structures, and hair follicle stem cells come from embryonic cells needing specific signals for development.

Obesity may worsen hair loss in men and increase hirsutism in overweight or obese individuals, with weight loss recommended for treatment.

Excessive hair growth in women can be harmless or signal serious health issues, and treatment often includes medication and hair removal, with noticeable results after 3-6 months.

Newly born mesenchymal cells quickly spread out in response to tissue tension during early development.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

Asia has made significant progress in tissue engineering and regenerative medicine, but wider clinical use requires more development.

Wounds on the face usually heal with scars, but understanding how some wounds heal without scars could lead to better treatments.

Gene network oscillations inside hair stem cells are key for hair growth regulation and could help treat hair loss.

Different tests are used to see how hair care products affect hair, and choosing the right test is important for accurate results.

Calcium microcapsules are better for long-term use in artificial dermal papilla, while barium microcapsules are good for short-term.

The KRTAP7-1 gene is very similar across different cattle and yak breeds and likely plays a role in hair strength and shape.

Human hair keratins can be turned into useful 3D biomedical scaffolds through a freeze-thaw process.

The study created a tool that mimics natural cell signals, which increased cell growth and could help with hair regeneration research.

A device was made in 2008 to measure hair loss severity. Other findings include: frizzy mutation in mice isn't related to Fgfr2, C/EBPx marks preadipocytes, Cyclosporin A speeds up hair growth in mice, blocking plasmin and metalloproteinases hinders healing, hyperbaric oxygen helps ischemic wound healing, amniotic membranes heal wounds better than polyurethane foam, rhVEGF165 from a fibrin matrix improves tissue flap viability and induces VEGF-R2 expression, and bFGF enhances wound healing and reduces scarring in rabbits.

The skin protects the body and is constantly renewed by stem cells; disruptions can lead to cancer.

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

Blood vessels and specific genes help turn cartilage into bone when bones heal.

Lamins are vital for cell survival, organ development, and preventing premature aging.

The shape of fibrous scaffolds can improve how stem cells help heal skin.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Tight junctions are key for skin protection and controlling what gets absorbed or passes through the skin.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.

Hair shedding is an active process that could be targeted to treat hair loss.

Wound healing insights can improve regenerative medicine.

PHBV nanofiber matrices help wounds heal faster when used with hair follicle cells.

The document concludes that the skin's immune system is complex, involving interactions with hair follicles, nerves, and microbes, and can protect or cause disease, offering targets for new treatments.
