Primary cilia affect the size and oil production of eye glands but not the oil's makeup.

Two siblings had a rare immune disorder caused by a FOXN1 gene mutation.

Atopic dermatitis may have genetic causes and can be treated with pharmacologic methods, glycerin creams, and controlling Staphylococcus aureus colonization.

Different types of skin cells play specific roles in development, healing, and cancer.

The Multi-Organ-Chip improves the growth and quality of skin and hair in the lab, potentially replacing animal testing.

Keratin 15 is not a reliable sole marker for identifying epidermal stem cells because it's found in various cell types.

Stem cells are crucial for tissue growth, cancer treatment, and disease modeling, but challenges remain in clinical use.

Smad-4 and Smad-7 are key in hair follicle development, with other Smads being less important.

Two-photon microscopy helps observe hair follicle stem cell behaviors in mice.

Stem cell niches are adaptable and key for tissue maintenance and repair.

Regenerative pharmacology, which combines drugs with regenerative medicine, shows promise for repairing damaged body parts and needs more interdisciplinary research.

Hair can regrow in large wounds through a process similar to how hair forms in embryos, and understanding this could lead to new treatments for hair loss or scarring.

Biomaterials combined with stem cells show promise for improving tissue repair and medical treatments.

Mongolian gerbils heal wounds differently than mice, with unique protein levels and gene expression that affect skin repair.

Current therapies cannot fully regenerate adult skin without scars; more research is needed for scar-free healing.

Melanocytes are important for skin and hair color and protect the skin from UV damage.

The document concludes that pig iPSCs show promise for transplant therapies and the field is advancing in controlling cell behavior for biology and medicine.

Alk1 in specific cells is crucial for proper nerve branching and hair function.

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

Ovol2 is crucial for hair growth and skin healing by controlling cell movement and growth.

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

High proliferation and cell delamination drive early skin development, while later stages may not rely on cell division orientation.

Glutamine metabolism affects hair stem cell maintenance and their ability to change back to stem cells.

Loss of Fz6 disrupts hair follicle and associated structures' orientation.

The Foxn1(-/-) nude mouse shows disrupted and expanded skin stem cell areas due to high Lhx2 levels.
