Phaeodactylum tricornutum extract helps hair follicle cells grow by activating the ERK1/2 pathway.

Segmental Vitiligo is a stable, early-onset form of vitiligo that responds well to early treatment and is ideal for repigmentation studies.

Mandarin duck sail feathers change with seasons due to hormones and genetic regulation.

Finding functions for unknown GPCRs is hard but key for making new drugs.

The TT genotype of a specific SNP in sheep is linked to better wool quality.

The gene Tfap2b is essential for creating a type of stem cell in zebrafish that can become different pigment cells.

Only skin melanocytes, not other types, can color hair in mice.

Cuttlefish ink melanin protects hair from UV damage.

We know less about human hair pigmentation than mouse coat color, but pH and cysteine levels are key factors.

Melanocytes in the outer root sheath are likely stem cells that grow fast but stay immature.

Melanocyte activity in hair follicles is linked to the hair growth cycle, being active in growth phases and inactive in rest phases.

We know a lot about mouse hair color, but not much about human hair color differences.

Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.

The document concludes that MGRN1 affects mouse fur color by interfering with a receptor's signaling, but its full role in the body is still unknown.

Fibroblasts can be turned into melanocytes for potential skin treatments.

Amelanotic melanocytes from hair follicles are immature and likely don't transfer melanosomes to keratinocytes.

Melanin is important for hair color, health, and UV protection.

ATP increases melanin production in skin after UV exposure, with the P2X7 receptor being crucial for this process.

Dynlt3 is important for melanosome transport and skin coloration.

Splenic eumelanin in C57BL/6 mice is different from hair eumelanin.

Melanocytes can regenerate around hair follicles in bullous pemphigoid, especially in patients with darker skin.
