Estrogen therapy can reduce skin aging but has cancer risks.

The document concludes that a better understanding of cell changes during wound healing could improve treatments for chronic wounds and other conditions.

Eating less sugar, milk, and saturated fats and more vegetables and fish may help treat and prevent acne.

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

Normal skin cell renewal doesn't need RAR signaling, but vitamin A-related skin thickening does.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

KGF and activin are crucial for skin healing and repair.

Hair, teeth, and mammary glands develop similarly at first but use different genes later.

Skin-derived precursors in hair follicles come from different origins but function similarly.

Wool follicles are complex, involving interactions between different cell types and structures.

Fetal skin heals without scarring due to unique cells and processes not present in adult skin healing.

Conditioned media from mesenchymal stem cell cultures could be a more effective alternative for regenerative therapies, but more research is needed.

Exosomes from dermal papilla cells can help grow hair and might treat hair loss.

Mutant mice help researchers understand hair growth and related genetic factors.

Mannosylerythritol lipids are good for skin and hair care products.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

Mice without the vitamin D receptor gene lose hair due to disrupted hair follicle cycles.

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

Wnt10b overexpression can regenerate hair follicles, possibly helping treat hair loss and alopecia.

Platelet-rich plasma may help in skin and hair treatments, and with muscle and joint healing, but more research is needed to fully understand its benefits and limitations.

Dermal Papilla cells are a promising tool for evaluating hair growth treatments.

Fat tissue cells are a promising option for healing various diseases, but more research is needed to ensure they are safe and effective.

The circadian clock influences the behavior and regeneration of stem cells in the body.

The conclusion is that hair growth can be improved by activating hair cycles, changing the surrounding environment, healing wounds to create new hair follicles, and using stem cell technology.

HFMs can help study hair growth and test potential hair growth drugs.

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

Treatment with plasma rich in growth factors improved hair density and thickness for hair loss patients.

Air pollution (PM10) increases skin inflammation and aging by reducing collagen and may trigger a repair response in skin cells.
