Cell aging can be both good and bad for tissue repair.

Dexpanthenol helps human hair follicle cells grow by preventing aging and death, and by supporting growth signals.

Bead-jet printing of stem cells improves muscle and hair regeneration.

Hair follicle stem cell transplants can reverse liver cirrhosis by blocking harmful cell activation.

The conclusion is that using drugs to block the TOR pathway might slow aging and prevent age-related diseases.

Maintaining DNA health in stem cells is key to preventing aging and tissue breakdown.

Skin stem cells are crucial for maintaining and repairing skin, with potential for treating skin disorders and improving wound healing.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

A special stem cell fluid can speed up wound healing and hair growth in mice.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

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

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

Cellular senescence has both cancer-blocking and cancer-promoting effects, and targeting senescent cells may improve health and lifespan.

Adipose-derived stem cells show potential for skin rejuvenation and wound healing but require more research to overcome challenges and ensure safety.

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

A new method using Y-27632 improves the growth and quality of human hair follicle stem cells for tissue engineering and therapy.

Hair follicle stem cells reduced hair loss and inflammation in mice with a condition similar to human alopecia.

SH-MSCs gel reduced IL-6 and increased TGF-β, suggesting it could treat alopecia.

ADSCs help in wound healing and skin regeneration but need more research for full understanding.

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

Exosomes from stem cells may help rejuvenate skin and regrow hair, but more research is needed.

Exosomal miRNAs from stem cells can help improve skin health and delay aging.

Oxidative stress affects hair loss in men with androgenetic alopecia.

Lamins are vital for cell survival, organ development, and preventing premature aging.

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

The calcineurin/NFAT pathway plays a significant role in the development and growth of a type of skin cancer called cutaneous squamous cell carcinoma.

Fibroblasts, cells usually linked to tissue repair, also help regenerate various organs and their ability decreases with age. Turning adult fibroblasts back to a younger state could be a new treatment approach.

Hormones affect skin aging, and treatments targeting hormonal balance may improve skin health.

Topical L-thyroxine may help with wound healing and hair growth but should be used short-term due to potential risks.

The mTOR signaling pathway is crucial for hair health and targeting it may lead to new hair loss treatments.
