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.

Hydrogen peroxide may have both positive and negative effects on wound healing, and its safe concentration for hair transplant surgery is unclear.

Reharvesting hair from donor sites using punch and strip methods can provide more hair for transplants and improve scar appearance.

Epithelial stem cells are crucial for tissue renewal and repair, and understanding them could improve treatments for damage and cancer.

Changing how mesenchymal stromal cells are grown can improve their healing abilities.

The document concludes that the understanding of scar formation is incomplete and current prevention and treatment for hypertrophic scars and keloids are not fully effective.

Some drugs can cause rare but potentially deadly skin reactions, and early treatment and avoiding the drug again are key.

Stem cells are crucial for skin repair and new treatments for chronic wounds.

New effective scar treatments are urgently needed due to the current options' limited success.

Nanoparticles improve drug delivery through the skin but more research is needed on their long-term effects and skin penetration challenges.

Periodontal ligament stem cells show promise for regrowing tissues but require more research for safe, effective use.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

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

Some drugs can cause skin, nail, and hair problems, which are important for healthcare professionals to recognize and report.

Fetal wound healing changes with development, affecting inflammation and collagen, which may influence scarring.

UV radiation can help sterilize wounds and promote healing but requires careful use to avoid damaging cells.

Nerves and chemicals in the body can affect hair growth and loss.

Different soft tissue fillers can cause various skin reactions; biodegradable fillers are safer and non-biodegradable ones like silicone can lead to long-term problems.

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

Stem cells from hair follicles can safely treat hair loss.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.

Mesenchymal stem cells show potential for skin healing and anti-aging, but more research is needed for safe use, especially regarding stem cells from induced pluripotent sources.

Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.

Toxic epidermal necrolysis is a severe skin condition often caused by drugs, with complex treatment and a high risk of death, but survivors usually heal without scars.

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

Understanding how fetal wounds heal could help improve healing in adults.

Certain immune system proteins are important for skin healing but can cause problems if there are too many of them.

Skin problems can be caused or worsened by physical forces and pressure on the skin.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.
