Hair follicle regeneration is possible but challenging, especially in humans, due to the need for specific cells and a better understanding of how they signal growth.

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.

The WNT signaling pathway is important in many diseases and targeting it could offer new treatments.

Skin fat helps with body temperature control and has other active roles in health.

Memantine may slightly improve memory in people with Down syndrome, but more research is needed.

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

Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

Hoxc genes control hair growth through Wnt signaling.

Skin and hair can regenerate after injury due to changes in gene activity, with potential links to how cancer spreads. Future research should focus on how new hair follicles form and the processes that trigger their creation.

Certain drugs change freshwater snail shells to a "banana" shape.

Turning scar-forming cells into fat cells can reduce scarring.

Runx genes are important for stem cell regulation and their roles in aging and disease need more research.

Scientists created early-stage hair follicles from human skin cells, which could help treat baldness and study hair growth.

Keratin gene expression helps understand different types of skin cells and their development, and should be used carefully as biological markers.

Activating β-catenin in mammary cells leads to changes that cause early-stage abnormal growths similar to skin structures.

CD4+ skin cells may be precursors to basal cell carcinoma.

Histone demethylases play a key role in the development of many diseases and may be targets for treatment.

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

MicroRNAs are crucial in controlling cell signaling, affecting cancer and tissue regeneration.

Some wound-healing cells can turn into fat cells around new hair growth in mice.

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

The research found that different types of fibroblasts are involved in wound healing and that some blood cells can turn into fat cells during this process.

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

Fat cells help recruit healing cells and build skin structure during wound healing.

Eph receptors and ephrins may be promising targets for treating diseases, but more understanding is needed for effective and safe therapies.

Lactate production is important for activating hair growth stem cells.

Different types of skin cells have unique genetic markers that affect how likely they are to spread cancer.

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

Stress can stop hair growth in mice, and treatments can reverse this effect.

Fat cells in the skin help start healing and form important repair cells after injury.
