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

Kartogenin may help treat hair loss by promoting hair growth and extending the hair growth phase.

HPH-15, a new compound, effectively reduces skin fibrosis in experiments without causing harm.

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

Higher TGF-β signaling may increase skin cancer risk in organ transplant recipients.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

Smad-4 and Smad-7 are key in hair follicle development, with other Smads being less important.

4-O-Methylhonokiol helps protect skin cells from growth-stopping effects of a protein by regulating growth-related pathways.

TGF-β is crucial for tissue repair and can cause diseases if not properly regulated.

Costunolide helps human hair cells grow and can stimulate hair growth in mice.

MSCs and their exosomes may speed up skin wound healing but need more research for consistent use.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

Wnt signaling is crucial for skin and hair development and its disruption can cause skin tumors.

The nucleus is key in controlling skin growth and repair by coordinating signals, gene regulators, and epigenetic changes.

Wnt/β-catenin and TGF-β pathways affect hair loss, and activating Wnt/β-catenin could be a potential treatment.

NF-κB signaling is crucial in many diseases and can be targeted for new treatments.

Bone Morphogenetic Proteins (BMPs) help control skin health, hair growth, and color, and could potentially be used to treat skin and hair disorders.

Ginsenoside Rg4 from ginseng may help hair growth by activating certain cell signals.

Chemicals and stem cells combined have advanced regenerative medicine with few safety concerns, focusing on improving techniques and treatment effectiveness.

Ginseng and its compounds may help hair growth and prevent hair loss, but more human trials are needed to confirm this.

Mice that can regenerate tissue have cells that pause in the cell cycle, which is important for healing, similar to axolotls.

Lung repair involves both dedicated and flexible stem cells, important for developing new treatments.

Hair follicle stem cells help maintain skin health and could improve skin replacement therapies.

Higher leptin levels link to hair loss.

Adult stem cells are important for tissue repair and have therapeutic potential, but more research is needed to fully use them.

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.

The document concludes that various signaling pathways and genetic factors are crucial for chicken feather development, affecting poultry quality.

Hair and skin healing involve complex cell interactions controlled by specific molecules and pathways, and hair follicle cells can help repair skin wounds.

High levels of ERK activity are key for tissue regeneration in spiny mice, and activating ERK can potentially redirect scar-forming healing towards regenerative healing in mammals.

Mesenchymal stem cells show promise for effective skin repair and regeneration.
