Grafted rodent and human cells can regenerate hair follicles, but efficiency decreases with age.

The Wnt/β-catenin pathway helps tissue regeneration but can also cause fibrosis, and drugs that inhibit this pathway may aid in healing skin and heart tissues.

Layer-by-Layer self-assembly is promising for biomedical uses like tissue engineering and cell therapy, but challenges remain in material safety and process optimization.

The article concludes that better understanding gene regulation related to seasonal changes can offer insights into the mechanisms of seasonal timing in mammals.

Children with loose anagen hair have easily pluckable hair due to root sheath problems, and it might improve without treatment.

New methods for skin and nerve regeneration can improve healing and feeling after burns.

Mouse skin can produce and process serotonin, with variations depending on hair cycle, body location, and mouse strain.

Skin development in mammals is controlled by key proteins and signals from underlying cells, involving stem cells for maintenance and repair.

A certain smell receptor in hair follicles can affect hair growth when activated by a synthetic sandalwood scent.

White lupin uses specific genes to grow root hairs and access phosphorus when it's scarce.

Muscles and nerves that cause goosebumps also help control hair growth.

Menopause reduces skin collagen and elasticity, and while estrogen therapy can help, its risks require careful consideration.

Cells in hair follicles help create fat cells in the skin by releasing a protein called Sonic Hedgehog.

Jasmonic acid and its derivatives play important roles in plant health and have potential uses in medicine and agriculture.

Human hair follicle stem cells can turn into multiple cell types but lose some of this ability after being grown in the lab for a long time.

Fat-derived stem cells, platelet-rich plasma, and biomaterials show promise for healing chronic skin wounds and improving soft tissue with few side effects.

Electrospun nanofibers show promise for enhancing blood vessel growth in tissue engineering but need further research to improve their effectiveness.
