Hair growth is influenced by interactions between skin layers, growth factors, and hormones, but the exact mechanisms are not fully understood.

Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.

Scientists developed a method to grow human fetal skin and digits in a lab for 3-4 weeks, which could help study skin features and understand genetic interactions in tissue formation.

Skin patterns form through molecular signals and genetic factors, affecting healing and dermatology.

Estrogen is important for keeping adult mouse nipple skin healthy by controlling certain cell signals.

SOX9 is essential for the development of various organs and hair follicles.

The conclusion is that effectively treating hair disorders is difficult due to the complex factors affecting hair growth and more research is needed to improve treatments.

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

Basonuclin 2 is vital for the development of facial bones, hair follicles, and male germ cells in adult mice, and its absence can lead to dwarfism and abnormal follicles.

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

Collagen XVII is important for skin aging and wound healing.

Mathematical modeling can improve regenerative medicine by predicting biological processes and optimizing therapy development.

Adult skin quickly reacts to short-term environmental and internal stress, leading to various skin issues and the need for protective measures.

Keratosis pilaris is often linked to genetic mutations and causes skin and hair abnormalities, regardless of those mutations.

EVAL membranes help create cell structures that can regrow hair follicles.

Exosomes from dermal papilla cells help hair growth by making hair follicle stem cells multiply and change.

Androgens reduce BMP2, which weakens the ability of certain cells to help hair stem cells become different types of cells.

Hair follicle dermal stem cells are key for regenerating parts of the hair follicle and determining hair type.

Researchers created immortal human skin cells with constant testosterone receptor activity to study hair loss and test treatments.

Scientists created a model using sheep cells to study hair root formation, which can test how different substances affect hair growth.

New treatment using engineered nanovesicles in hydrogel improves hair growth by repairing hair follicle cells in a mouse model of hair loss.

Skin cell clumping for hair growth is improved by a protein called fibronectin, which helps cells stick and move better.

Marine-derived saccharides may help reduce aging effects on skin and hair by promoting cell growth and collagen production.

Different types of sun exposure damage skin cells and immune cells, with chronic exposure leading to more severe and lasting damage.

Scientists created tiny particles that release medicine on the skin and in hair, working better at certain pH levels and being safe for skin cells.

Hair and skin can regenerate without bulge stem cells due to other compensating cells.

Hair loss in men might be linked to changes in cell energy factories.

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.
