Immune cells are essential for early hair and skin development and healing.

Skin health and repair depend on the signals between skin stem cells and their surrounding cells.

The right cells and signals can potentially lead to scarless wound healing, with a mix of natural and external wound healing controllers possibly being the best way to achieve this.

Certain genes are more active during wound healing in axolotl and Acomys, which could help develop materials that improve human wound healing and regeneration.

Different fibroblasts play key roles in skin healing and scarring.

Skin cells called dermal fibroblasts are important for skin growth, hair growth, and wound healing.

Tiny particles called extracellular vesicles show promise for skin improvement and anti-aging in facial care but face challenges like low production and lack of research.

Exosomes may improve skin, scars, hair growth, and fat grafts in plastic surgery, but more research is needed.

Keratinocytes show more TGF-β system activity and collagen production as they age, which might affect wound scarring.

Different immune cells like platelets, mast cells, neutrophils, macrophages, T cells, B cells, and innate lymphoid cells all play roles in skin wound healing, but more research is needed due to inconsistent results and the complex nature of the immune response.

Mast cells likely promote skin scarring and fibrosis, but their exact role is still unclear.

Blocking COX, especially COX-2, in the skin can reduce inflammation and pain and may help prevent skin cancer.

Facial plastic surgery has evolved to focus on less invasive techniques and innovative technologies for cosmetic and reconstructive procedures.

Large-scale fibronectin nanofibers help heal wounds and repair tissue in a skin model of a mouse.

Artificial skin development has challenges, but new materials and understanding cell behavior could improve tissue repair. Also, certain growth factors and hydrogel technology show promise for advanced skin replacement therapies.

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

Wnt signaling is crucial for skin wound healing and reducing scars.

Advancements in creating skin grafts with biomaterials and stem cells are promising, but more research is needed for clinical application.

The study found that expanded skin regenerates similarly to normal skin, with 77 genes playing a role in the process.

Young C57BL/6 mice heal better than BALB/c mice, and older mice heal faster but regenerate worse.

Deer antler stem cell fluid helps regenerate tissue better than fat-derived stem cell fluid.

Mesenchymal stem cells show promise for treating various skin conditions and may help regenerate hair.

Various treatments can improve post-acne scars, but results vary.

The hydrogel helps heal wounds and regrow hair by mimicking a baby's environment.

Fetal skin cells from a cell bank heal wounds faster and with less scarring than adult cells.

Mast cells and VEGF contribute to post-surgery adhesions, and blocking VEGF can reduce these adhesions; also, certain factors affect wound healing and fetal skin heals differently with age.

3D cultivation and prenatal stem cell exosomes improve stem cell treatment results, especially for hair loss and age-related issues.

The mouse model shows potential for understanding and improving scarless wound healing, and Wnt-4 and TGF-β1 play a role in wound healing and scar formation.

Certain hairstyles can cause scalp diseases, smoking is linked to hair loss, 5% minoxidil foam is effective for hair loss treatment, and various factors influence wound healing and hair growth.

ECM-inspired wound dressings can help heal chronic wounds by controlling macrophage activity.
