Researchers created a fully functional, bioengineered skin system with hair from stem cells that successfully integrated when transplanted into mice.

The conclusion is that understanding how feathers and hairs pattern can help in developing hair regeneration treatments.

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

Hair growth and development are controlled by specific signaling pathways.

Using bioreactors, scientists can grow more skin stem cells that keep their ability to regenerate skin and hair.

BMP signaling is essential for the development of touch domes.

A new tool can analyze hair to detect changes due to hormones, genetics, and aging.

The research shows that a gene called Wnt3 affects hair growth and structure, causing short hair and balding when overactive.

Rac1 is essential for proper hair structure and color.

Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.

Male and female human hairs have different microscopic structures that can help in forensic analysis.

Skin has specialized touch receptors that can tell different sensations apart.

The right amount of retinoic acid is essential for normal hair growth and development.

The enzymes Tet2 and Tet3 are important for skin cell development and hair growth.

Connarus semidecandrus Jack extract promotes hair growth and thickness, reduces prostate cancer cell growth, and could potentially be used as a treatment for hair loss.

Black-tailed deer have four types of pelages and molt twice a year.

Defective mink guard hairs have split tips and missing cuticle cells, causing a metallic sheen.

Antler velvet hair and body hair of red deer have different structures that help with protection and insulation.

Most dogs have hair whorls on their chest and limbs, with shelter dogs and short-haired dogs having more chest whorls.

Environmental factors like temperature and nutrition affect hair growth, with humans showing seasonal hair growth differences.

EPR spectroscopy showed that spontaneous hair growth results in thicker skin and less pigmented hair than depilation-induced growth.

Melatonin improves cashmere goat hair growth and quality by increasing antioxidants and reducing cell death.

The PTGER2 gene is highly active in Cashmere goat skin and its activity changes with the hair growth cycle.

Peps help Arabidopsis plants grow more root hairs by affecting specific genes and calcium signaling.

Measuring reproductive hormones in brown bear hair could help identify their sex and reproductive state, but better collection methods or lab techniques are needed.

South American camelids should be sheared early, fleece type affects fiber quality, and the S/P follicle ratio doesn't distinguish between Bolivian llama genotypes.

Different proteins are linked to the varying thickness of sheep and goat hair types.

Melatonin implants can change the seasonal prolactin levels and hair growth in adult cashmere goats but not in juveniles, and don't delay spring moult for better fiber harvesting.

Laser ablation ICP-MS is effective for tracking trace elements in polar bear hair over time.

Eclipta alba extract was found to be effective in promoting hair growth in hairless mice.
