Stem cell therapies show promise for treating various diseases but face challenges in clinical use and require better monitoring techniques.

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

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

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

Good feather growth in poultry needs the right balance of proteins, amino acids, minerals, and vitamins.

All-trans retinoic acid at high doses harms goat hair growth cells and could be bad for hair growth.

The skin protects the body, regulates temperature, senses touch, and makes vitamin D.

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

Feather patterns are influenced by enhancers and chromatin looping, and the structure of protein complexes important for hair growth has been detailed.

The cause and importance of misplaced oil glands in the hair follicle are not well understood.

Stem cells help remove dead cells to keep tissues healthy by balancing cell replacement and clearance.

The document explains how hair follicles develop, their structure, and how they grow.

Melanocytes produce melanin; their defects cause vitiligo and hair graying, with treatments available for vitiligo.

Horse skin has a layered epidermis, a dermis with hair follicles, sweat and sebaceous glands, and is supplied by small arteries.

Modern hair restoration techniques can effectively treat hair loss and provide natural-looking results.

Aging causes hair to gray and thin, with the timing of graying varying by race, and factors like oxidative stress and genetics can lead to hair loss.

Auxin and ethylene hormones both work together and against each other to control plant growth.

Stromal stem cells may help heal wounds by becoming structural cells or affecting the immune system, but more research is needed to understand how.

Certain proteins, Lgr5 and Lgr6, are important markers of adult stem cells and are involved in tissue repair and cancer development.

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

Vitamin D receptor interacts with certain dietary components to help prevent diseases and regulate hair growth.

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

Androgens can cause hair growth in some areas and hair loss on the scalp.

Periodontal ligament stem cells show promise for regrowing tissues but require more research for safe, effective use.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

Hair ages due to genetics and environmental factors, leading to graying and thinning, with treatments available for some conditions.

Skin fat helps with body temperature control and has other active roles in health.

Fetal skin heals without scarring due to unique cells and processes not present in adult skin healing.

Mice studies show that Protein Phosphatase 2A is crucial for cell growth, development, and disease prevention.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.
