Apoptosis is essential for human skin development and forming a functional epidermis.

VEGFR-2 activation is likely involved in hair follicle growth, survival, and development.

Caspases are enzymes important for both cell death and various non-lethal cell functions, affecting head development and hair growth, with different caspases playing specific roles.

Cathepsin L is essential for normal hair growth and development.

Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.

IGF-1 injections help mice grow more hair by increasing cell growth and blocking a hair growth inhibitor.

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.

Hormones cause hair loss by affecting cell growth and weakening cell attraction.

MicroRNA-214 is important for skin and hair growth because it affects the Wnt pathway.

Future hair loss treatments should aim to extend hair growth, reactivate resting follicles, reverse shrinkage, and possibly create new follicles, with gene therapy showing promise.

Nanoparticles improve drug delivery through the skin but more research is needed on their long-term effects and skin penetration challenges.

The study found that a specific area of the hair follicle helps start hair growth by reducing the blocking effects on certain cells and controlling growth signals.

Hdac1 and Hdac2 help maintain and protect the cells that control hair growth.

Human skin has multiple layers and functions, with key roles in protection, temperature control, and appearance.

Sp6 promotes tooth development by reducing follistatin levels.

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

Human stem cells were turned into cells similar to those that help grow hair and showed potential for hair follicle formation.

S100A4 and S100A6 proteins may activate stem cells for hair follicle regeneration and could be potential targets for hair loss treatments.

We need better treatments for hair loss, and while test-tube methods are helpful, they can't fully replace animal tests for evaluating new hair growth treatments.

Hair follicle biology advancements may lead to better hair growth disorder treatments.

Alopecia areata and vitiligo share immune system dysfunction but differ in specific immune responses and affected areas.

Innate immunity genes in hair follicle stem cells might have new roles beyond traditional immune functions.

Blocking cell death in hair follicles can lead to impaired hair growth.

Artemis protein may help control hair growth and health by influencing cell processes.

Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.

KLF4 is important for maintaining stem cells and has potential in cancer treatment and wound healing.

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

The hair follicle bulge is an important area for adult stem cells involved in hair growth and repair, with potential for medical use needing more research.

The research identified genes and pathways important for sheep wool growth and shedding.

Mice without the Sp6 gene have problems developing several body parts, including hair, teeth, limbs, and lungs.
