Melanocyte development from neural crest cells is complex and influenced by many factors, and better understanding could help treat skin disorders.

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

Aging in hair follicle stem cells leads to hair graying, thinning, and loss.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

Applying certain inhibitors to the skin can promote hair growth without harming cells.

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

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.

The document concludes that skin stem cells are important for hair growth and wound healing, and could be used in regenerative medicine.

The document concludes that more research is needed to understand airway repair and to improve tissue engineering for lung treatments.

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

Imiquimod cream activates hair follicle stem cells and causes early hair growth by changing immune cells and certain protein expressions.

Skin health and repair depend on the signals between skin stem cells and their surrounding cells.

Using human fat tissue derived stem cells in micrografts can safely and effectively increase hair density in people with hair loss.

The study concluded that similar pathways regulate hair growth in dogs and mice, and these pathways are disrupted in dogs with Alopecia X, affecting stem cells and hormone metabolism.

Hair loss in Androgenetic Alopecia is caused by genetics, aging, and lifestyle, leading to hair follicle shrinkage and related health risks.

Different species use the same genes for tooth regeneration.

Skin cells show flexibility in healing wounds and forming tumors, with potential for treating hair disorders and chronic ulcers.

The Notch signaling pathway is important for hair follicle development and could help create treatments for hair disorders.

Enzymes called PADIs play a key role in hair growth and loss.

The Msi2 protein helps keep hair follicle stem cells inactive, controlling hair growth and regeneration.

Activating TERT in mice skin boosts hair growth by waking up hair follicle stem cells.

PDGF signaling is crucial for maintaining fat stem cells in the skin, and its level of activation can either preserve these cells or cause fibrosis.

Muscles and nerves that cause goosebumps also help control hair growth.

YAP and TAZ proteins are necessary for the development of two types of skin cancer.

Smad1 and Smad5 are essential for hair follicle development and stem cell sleepiness.

Stem cell niches support, regulate, and coordinate stem cell functions.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

Ephrins slow down skin and hair follicle cell growth.

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

New drugs for heart disease may be developed from molecules secreted by stem cells.
