The exact identity of skin stem cells and how skin cells differentiate is not fully known.

The May issue discussed publishing agreements and four studies on cholesterol in hair, cancer cell changes, hormones in the uterus, and skin protein effects.

Older hair follicle stem cells have a reduced ability to renew themselves, leading to more hair loss.

Both Th1 and Th2 immune responses are increased in alopecia areata, with Th2 response more strongly linked to how severe the disease is.

Topical tofacitinib is effective in promoting hair growth for non-scarring alopecia.

The Nd:YAG laser is a successful and safe way to treat ingrown and pincer nails.

The woman's rare combination of diseases suggests an unknown factor may predispose individuals to multiple endocrine diseases.

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.

Syphilitic alopecia is a rare hair loss condition in secondary syphilis that looks similar to another condition but can be diagnosed with specific tests and responds to antibiotics.

Alexander the Great's engineers built a causeway using a natural sand bridge, some tiger moths avoid bats by mimicking toxic relatives' sounds, early metabolism and RNA enzymes support the ancient RNA world theory, and vitamin D is crucial for hair growth and its absence can cause baldness.

Stem cells preservation in AGA could be a potential therapy, but more cases needed.

The guidelines recommend informed consent for gender-affirming treatments and stress the importance of personalized, culturally sensitive care for transgender individuals.

The document concludes that better targeted treatments are needed for wound healing, and single-cell technologies may improve cell-based therapies.

Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.

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

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

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

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.
