Keratin 15 is not a reliable sole marker for identifying epidermal stem cells because it's found in various cell types.

Activating ER-β, not ER-α, improves skin cell growth and wound healing.

Epimorphin, a protein, plays a key role in the development of hair follicles in human fetuses, but it doesn't help in maintaining the stem cell population of the follicular skin layer.

TGF-alpha is present in sheep and ferret skin and may affect hair growth without directly stimulating cell proliferation.

Different materials affect the growth of brain cells and fibroblasts, with matrigel being best for brain cell growth.

The document concludes that while some organisms can regenerate body parts, mammals generally cannot, and cancer progression is complex, involving mutations rather than a strict stem cell hierarchy.

A new ethical skin model using stem cells offers a reliable alternative for dermatological research.

PRP treatment may stimulate hair growth by promoting blood vessel formation, increasing growth factors, and preventing cell death.

Thymosin β4 helps improve skin healing and reduce scarring.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

Calreticulin has roles in healing, immune response, and disease beyond its known functions in the endoplasmic reticulum.

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

Transplant success has improved with better immunosuppressive drugs and donor matching.

Deregulation of stem cell function is central to the development of some cancers.

Prolactin affects hair growth and skin conditions, and could be a target for new skin disease treatments.

A surface with VEGF can specifically capture endothelial cells from flowing fluids.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

Hair follicle regeneration in skin grafts may be possible using stem cells and tissue engineering.

Human hair follicle cells can be successfully transformed into different types of cells, but not more efficiently than other adult cells.

Using polyethylenimine-DNA to deliver the hTERT gene can stimulate hair growth and may be useful in treating hair loss, but there could be potential cancer risks.

Scube3 gene affects mouse embryo growth in multiple areas, but needs more research.

Scientists found ways to identify and collect skin stem cells, which vary by skin area and are delicate.

Hyaluronic acid and versican are important for skin healing and hair growth and might help in regenerative medicine.

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

Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

Photobiomodulation therapy using red and near-infrared light can reduce inflammation and aid in healing various conditions.

Understanding phenotypic plasticity is crucial for developing effective cancer therapies.

The paper concludes that understanding melanocyte development can help in insights into skin diseases and melanoma diversity.

Nerve signals are crucial for hair follicle stem cells to become skin stem cells and help in wound healing.

Human skin can make serotonin and melatonin, which help protect and maintain it.
