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.

Hair can regrow in large wounds through a process similar to how hair forms in embryos, and understanding this could lead to new treatments for hair loss or scarring.

Blocking Wnt/β-catenin signaling with EGF receptor is necessary for proper hair growth.

Different processes create patterns in skin and things like hair and feathers.

The conclusion is that skin and hair patterns are formed by a mix of cell activities, molecular signals, and environmental factors.

New treatments targeting the Hedgehog pathway can help treat advanced skin cancer but may have side effects and their effectiveness in early stages is unknown.

Green tea compound EGCG helps mink hair follicles grow by affecting certain cell growth pathways.

Bioluminescence imaging can track hair follicle cells and help study hair regrowth.

Glutamic acid helps increase hair growth in mice.

Skin's epithelial stem cells are crucial for repair and maintenance, and understanding them could improve treatments for skin problems.

ILK is essential for skin development, pigmentation, and healing.

BMP4-related anomalies can cause a wide range of eye, brain, and hand/foot problems, and new cases show this variability.

Foxn1 gene regulation is crucial for thymus development but not for hair growth.

Polycomb Repressive Complex 2 is not needed for hair regeneration.

Stopping S100A3 activity slows down hair growth in mice.

Different ectodermal organs like hair and feathers regenerate differently, with specific stem cells and signals involved in their growth and response to the environment.

Immune cells are crucial for hair growth and preventing hair loss.

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

COX2 and ATP synthase control the size of hedgehog spines.

Different genes and pathways are active in yak skin and hair cells, affecting hair growth and immune responses.

Aging reduces skin cell renewal and defense against germs due to TGFbeta, but blocking TGFbeta could help restore these functions.

Different types of stem cells in the skin contribute to the variety of melanoma forms.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

TLR3 activation helps improve skin and hair follicle healing in mice.

Activating TLR3 helps improve skin and hair follicle regeneration after wounds.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

The circadian clock is crucial for tissue renewal and regeneration, affecting stem cell functions and having implications for health and disease.
