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

Ionizing radiation causes irreversible skin damage, with single doses leading to acute injury and hair graying, and fractional doses causing more severe long-term tissue damage.

Quercetin significantly helps hair growth by activating hair follicles and improving blood vessel formation around them.

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

sPLA2-IIA increases growth in hair follicle stem cells and cancer cells, suggesting it could be targeted for hair growth and cancer treatment.

Some therapies using stem cells and platelet-rich plasma may help treat osteoarthritis, but more research is needed to ensure they are safe and effective.

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.

Two-photon microscopy helps observe hair follicle stem cell behaviors in mice.

Hair follicle cells help maintain and support stem cells and blood cell formation.

Lgr5 is a marker for active, self-renewing stem cells in the intestine and skin, important for tissue maintenance.

CD34 marks potential stem cells in dog hair follicles.

Researchers found a good way to isolate hair follicle stem cells from newborn goats for further study.

Periodontal ligament stem cells show promise for regrowing tissues but require more research for safe, effective use.

Canine epidermal neural crest stem cells could be a promising treatment for spinal cord injuries in dogs.

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.

Hair follicles and deer antlers regenerate similarly through stem cells and are influenced by hormones and growth factors.

Implanting hair-follicle stem cells in mice brains helped repair brain bleeding and reduced brain inflammation.

Skin development in mammals is controlled by key proteins and signals from underlying cells, involving stem cells for maintenance and repair.

Scientists created a new cell line from Cashmere goat hair and found that cytokeratin 13 is a unique marker for certain skin cells.

Implanted special stem cells from hair follicles helped heal wounds faster and with less scarring in mice.

Targeting colon cancer stem cells might lead to better treatment results.

Certain proteins, Lgr5 and Lgr6, are important markers of adult stem cells and are involved in tissue repair and cancer development.

High LGR5 levels in glioblastoma indicate poor prognosis and are essential for cancer stem cell survival.

The conclusion is that fat grafting is safe and effective but carries risks that need careful management.

TLR3 signaling enhances the immunosuppressive properties of human periodontal ligament stem cells.

Metabolic Syndrome is linked to several skin conditions, and stem cell therapy might help treat them.

Some brain cancer cells avoid immune system detection, and certain treatments could target this to slow their growth; also, certain fat cell precursors help regenerate hair and skin after injury.

ADSC-CM treatment improved hair density and thickness in women with hair loss, safely and effectively.

Hair follicle regeneration needs special conditions and young cells.

The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.
