TRPA1 is crucial for mechanical sensitivity in skin sensory neurons.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

The research shows that a gene called Wnt3 affects hair growth and structure, causing short hair and balding when overactive.

Msx and Dlx genes are crucial for development, controlling cell behaviors like growth and differentiation through their roles as gene regulators.

Nerves are crucial for the regeneration of various body parts in many animals.

Mice lacking the PPARγ gene in their fat cells had almost no fat tissue, severe metabolic problems, and abnormal development of other fat-related tissues.

Planarian regeneration begins with a specific gene activation caused by injury, essential for healing and tissue regrowth.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Scientists have found a way to create hair follicles from skin cells of newborn mice, which can grow and cycle naturally when injected into adult mouse skin.

The cuneate nucleus has two main neuron types: relay neurons and interneurons.

A gene called APCDD1, which controls hair growth, is found to be faulty in a type of hair loss called hereditary hypotrichosis simplex.

The hedgehog signaling pathway is crucial for hair growth but not for the initial creation of hair follicles.

Alopecia areata is an autoimmune condition causing hair loss due to the immune system attacking hair follicles, often influenced by genetics and stress.

Bone Morphogenetic Proteins (BMPs) help control skin health, hair growth, and color, and could potentially be used to treat skin and hair disorders.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Early development of hair, teeth, and glands involves specific signaling pathways and cellular interactions.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

Memory T cells in the skin balance staying put and moving into the blood, clustering around hair follicles, and increasing in number after infection.

Young adults have about 230,000 tactile nerve fibers, decreasing 5-8% per decade with age.

Postpartum depression is linked to changes in brain chemicals, inflammation, stress, and certain genes, and can potentially be identified by markers like specific steroids, serotonin levels, and vitamin D levels.

Sonic hedgehog signaling is crucial for hair growth and maintaining hair follicle identity.

Adam10 enzyme is crucial for healthy skin and proper Notch signaling.

Modulating BMP activity changes the number, size, shape, and type of ectodermal organs.

Skin grafts on mice can cause an immune response leading to hair loss, useful for studying human hair loss conditions.

Mouse hair follicle cells briefly grow during the early hair growth phase, showing that these cells are important for starting the hair cycle.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

Mice hair growth patterns get more complex with age and can change with events like pregnancy or injury.

Liposomes and niosomes improve finasteride delivery for hair loss treatment.

Minoxidil can help grow hair in mice by making cells grow and improving hair quality. More research needed.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.
