Stem cells and their exosomes show promise for repairing tissues and healing wounds when delivered effectively, but more research is needed on their tracking and optimal use.

Activating TLR3 improves the healing and immune properties of periodontal ligament stem cells.

Plant adaptogens may help treat skin diseases and improve skin health, but more research is needed to fully understand how they work.

Adipose-derived stem cells can help repair and improve eye tissues and appearance.

The secretome from mesenchymal stromal cells shows promise for improving facial nerve injury treatment.

Mice with a virus similar to COVID-19 had skin damage, but a special treatment helped repair it.

The Notch signaling pathway is important for hair follicle development and could help create treatments for hair disorders.

Diabetes causes lasting cell dysfunctions, leading to serious complications even after blood sugar is controlled.

Aging changes hair stem cells and their environment, leading to gray hair and hair thinning, but understanding these changes could help develop treatments for hair regeneration.

Innate lymphoid cells help control skin bacteria by regulating sebaceous glands.

MicroRNA-148a is crucial for maintaining healthy skin and hair growth by affecting stem cell functions.

Treg cell-based therapies might help treat hair loss from alopecia areata, but more research is needed to confirm safety and effectiveness.

NIPP1 is important for healthy skin and could help treat skin inflammation.

Lower SMAD2/3 activation predicts more severe skin cancer.

PBX1 helps reduce aging and cell death in hair follicle stem cells by decreasing DNA damage, not by improving DNA repair.

The document concludes that understanding adult stem cells and their environments can help improve skin regeneration in the future.

The Wnt/β-catenin signaling pathway is important for skin wound healing and affects inflammation, cell growth, and other healing processes.

Stem cells can help other stem cells by producing supportive factors.

Metabolism plays a key role in determining stem cell fate.

The CUBIC protocol allows detailed 3D visualization of proteins in mouse skin biopsies.

Immune cells are essential for skin regeneration using biomaterial scaffolds.

PRC2 is essential for maintaining intestinal cell balance and aiding regeneration after damage.

Aging slows wound healing due to weaker cells and immune response.

Hidradenitis suppurativa is a skin disease caused by the breakdown of the skin's natural immune barriers, especially around hair follicles.

The gel with icariin speeds up wound healing, reduces scarring, and helps hair growth by controlling BMP4 signaling. It also reduces inflammation and improves wound quality in mice, adapts to different wound shapes, and gradually releases icariin to aid healing. It also prevents too much collagen and myofibroblast formation during skin healing.

A specific signal from hair cells controls the tightening of the surrounding muscle, which is necessary for hair shedding.

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.

Ephrins slow down skin and hair follicle cell growth.

Wnt/ß-catenin signaling is crucial for regulating skin stem cells and hair growth, with the right levels and timing needed for proper function.

Using defensins to activate stem cells may improve skin aging signs without causing inflammation.
