New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.

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.

AcSDKP may help prevent skin and hair aging and promote their growth.

Improved understanding of stem cell mechanisms can enhance skin tissue engineering.

A specific RNA molecule, circCOL1A1, affects the growth and quality of goat hair by interacting with miR-149-5p and influencing cell growth pathways.

TLR3 activation helps improve skin and hair follicle healing in mice.

Activating TLR3 helps improve skin and hair follicle regeneration after wounds.

Hair follicles help absorb and store topical compounds, aiding targeted drug delivery.

Gamma-rays exposure during the resting phase of hair growth can damage hair regeneration and color in mice.

Gamma-ray exposure can cause long-lasting damage to hair follicles, affecting hair structure and color.

Targeting the protein Caveolin-1 might help treat a type of scarring hair loss called Frontal Fibrosing Alopecia.

Future research should focus on making bioengineered skin that completely restores all skin functions.

Glycyrrhizic acid and licorice extract can significantly reduce unwanted hair growth.

LGR5 helps maintain corneal cell characteristics and prevents unwanted changes by controlling specific cell signaling pathways.

Gata6 is important for protecting hair growth cells from DNA damage and keeping normal hair growth.

Regenerative therapies show promise for treating vitiligo and alopecia areata.

Hair follicles are essential for skin health, aiding in hair growth, wound healing, and immune function.

Vitamin D and calcium are important for quick and effective skin wound healing.

Human hair follicles may provide a noninvasive way to diagnose diseases and have potential in regenerative medicine.

Removing Mediator 1 from certain mouse cells causes teeth to grow hair instead of enamel.

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.

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.

Advancements in hair biology include new treatments and tools for hair growth and alopecia.

Basal cell carcinomas may differentiate similarly to hair follicles and could be influenced by hair cycle-related treatments.

Vitamin D has potential benefits for cancer prevention, heart health, diabetes, obesity, muscle function, skin health, and immune function, but clinical results are mixed and more research is needed.

Keratin 15 expression in skin cells is regulated by two mechanisms involving PKC/AP-1 and FOXM1.

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.

Plant extracts may help prevent or reverse hair graying.
