Stem cell behavior varies with stimuli, and lineage changes can happen without affecting stem cell division.

Hair has unevenly distributed proteins and lipids, with lipids mainly in the cuticle and proteins in the cortex and medulla.

Mutations in the HEPHL1 gene cause abnormal hair and cognitive issues.

Researchers created human hair follicles using a new method that could help treat hair loss.

Miz1 is essential for proper hair structure and growth.

Dermal papilla cells are crucial for hair growth and can induce new hair follicles.

The connective tissue around hair follicles changes structure throughout the hair cycle.

The hair's outermost surface has multiple layers of lipids and proteins.

Females have higher estrogen receptor levels in hair than males, and these levels decrease in white hair compared to black hair.

The EDAR gene mutation leads to thinner and more deformed hair shafts.

Hair keratins are mainly on macrofibrils in the cortex and in the endocuticle in the cuticle.

Activating β-catenin in certain skin cells speeds up hair growth in mice.

MED1 is essential for normal hair growth and maintaining hair follicle stem cells.

A patient grew extra hair on their ears after treatment for testicular cancer, possibly due to hormonal changes or genetics.

Hair and wool have complex microscopic structures with microfibrils and varying cystine content.

The method allows for 3D tracking of hair follicle stem cells and shows they can regenerate hair for up to 180 days.

The document concludes that specific cells are essential for hair growth and more research is needed to understand how to maintain their hair-inducing properties.

K15 staining helps distinguish basal cell carcinoma from trichoepithelioma.

Hairless protein helps control hair growth by regulating vitamin D receptor activity.

Activated LEF/TCF complexes are crucial for hair development and cycling.

Hair is mostly made of three protein types: helical, high-sulfur, and high-tyrosine.

Mechanical forces are crucial for hair regeneration in skin organoids.

The mK6irs1/Krt2-6g gene likely causes wavy hair in mice.

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

Horse hair follicles could be a new source of stem cells for healing horses.

β-catenin helps hair follicle stem cells grow by activating a specific cell pathway.

Conditioned medium from keratinocytes can improve hair growth potential in cultured dermal papilla cells.

Telocytes, cells with long extensions, are vital for hair growth because they produce Wnt signals, which are necessary for hair follicle regeneration.

The genes OVOL1 and OVOL2 are important for hair growth and may be involved in a type of skin tumor.
