Stem cells help remove dead cells to keep tissues healthy by balancing cell replacement and clearance.

ATP-dependent chromatin remodeling is crucial for skin development and stem cell function.

The Wnt/β-catenin pathway helps tissue regeneration but can also cause fibrosis, and drugs that inhibit this pathway may aid in healing skin and heart tissues.

Tiny particles called extracellular vesicles could help with skin healing and hair growth, but more research is needed.

Touch sensitivity in mouse skin decreases during hair growth due to changes in touch receptors.

Different stem cells have benefits and challenges for tissue repair, and more research is needed to find the best types for each use.

Wnt7a protein is crucial for development and tissue maintenance and plays varying roles in diseases and potential treatments.

Hair follicles can be used to quickly assess drug effects in cancer treatment.

Tight junctions are key for skin protection and controlling what gets absorbed or passes through the skin.

Overexpressing Tβ4 in goats' hair follicles increases cashmere production and hair follicle growth.

Using a fractional laser can stimulate hair growth, but the intensity and duration of inflammation are crucial. Too much can cause ulcers and scarring. Lower beam energy and fewer treatments are recommended to avoid damage.

Mice lacking the PPARγ gene in their fat cells had almost no fat tissue, severe metabolic problems, and abnormal development of other fat-related tissues.

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

Blocking the Wnt pathway could lead to new treatments for cancer and tissue repair but requires careful development to avoid side effects.

RADA16 is a promising material for tissue repair and regenerative medicine but needs improvement in strength and cost.

Lyophilized platelet-rich plasma is beneficial and effective for various medical treatments, including tissue regeneration and hair regrowth.

PlacMA hydrogels from human placenta are versatile and useful for cell culture and tissue engineering.

Exosomes show promise for tissue repair and regeneration with advantages over traditional cell therapies.

Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.

3D cell-derived matrices improve tissue regeneration and disease modeling.

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.

HPV genes in mice improve ear tissue healing by speeding up skin growth and repair.

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

The research found a new way to heal chronic skin ulcers by turning certain cells into skin tissue using specific factors.

Wounds can regenerate hair in young mice, but this ability declines with age, offering insights for improving tissue regeneration in the elderly.

Certain proteins, Lgr5 and Lgr6, are important markers of adult stem cells and are involved in tissue repair and cancer development.

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.

Researchers created a 3D-printed skin model that grew human hair when grafted onto mice by improving blood supply to the grafts.

DPP4 is important for scarring and skin regeneration, and managing its activity could improve skin healing treatments.

Understanding different types of skin cells, especially fibroblasts, can lead to better treatments for wound healing and less scarring.
