Human dermal stem cells can become functional skin pigment cells.

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

New methods for skin and nerve regeneration can improve healing and feeling after burns.

The document concludes that understanding hair and feather regeneration can help develop new regenerative medicine strategies.

Certain signals and genes play a key role in hair growth and regeneration, and understanding these could lead to new treatments for skin regeneration.

Older skin has higher cancer risk due to inflammation and stem cell issues.

Human Schwann cells can be quickly made from hair follicle stem cells for nerve repair.

Stem cell therapy may help treat tough hair loss cases.

The Ovol2-Zeb1 circuit is crucial for skin healing and hair growth by guiding cell movement and growth.

Bone-forming cells grow well in 3D polymer scaffolds with 35 µm pores.

Stem cell technologies and regenerative medicine, including platelet-rich plasma, show promise for hair restoration in treating hair loss, but more research is needed.

Bioactive molecules show promise for improving skin repair and regeneration by overcoming current challenges with further research.

Dermal papilla cell vesicles can boost hair growth genes in fat stem cells.

A specific RNA increases hair stem cell growth and skin healing by affecting a protein through interaction with a microRNA.

Hair follicle stem cells can become motor neurons and reduce muscle loss after nerve injury.

The engineered skin substitute helped grow skin with hair on mice.

Stem cells and their exosomes show promise for repairing tissues and healing wounds when delivered effectively, but more research is needed on their tracking and optimal use.

The LncRNA AC010789.1 slows down hair loss by promoting hair follicle growth and interacting with miR-21 and the Wnt/β-catenin pathway.

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.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

SOX2 is crucial for skin cell function and hair growth, and it plays a role in skin cancer and wound healing.

Melanocytes produce melanin; their defects cause vitiligo and hair graying, with treatments available for vitiligo.

3D bioprinting with special hydrogels can create artificial skin that heals wounds and regrows hair in mice.

Melatonin can help or hinder hair growth depending on the dose.

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

Umbilical cord blood is a valuable source of stem cells for medical treatments, but its use is less common than other transplants, and there are ethical issues to consider.

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

Advancements in tissue engineering show promise for hair follicle regeneration to treat hair loss.

Topical drugs and near-infrared light therapy show potential for treating alopecia.

Advanced human skin models improve drug development and could replace animal testing.
