Nail stem cells and Wnt signaling are important for fingertip regeneration but not sufficient for regenerating more complex limb structures.

The conclusion is that teeth, hair, and claws have similar stem cell niches, which are important for growth and repair, and more research is needed on their regulation and potential markers.

Newly found stem cells in horse hooves show promise for treating a hoof disease called laminitis.

Epidermal stem cells create and maintain skin structures like hair and nails through specific signaling pathways and vary by location and function.

Human nails and hair follicles have similar gene activity, especially in the cells that contribute to their growth and development.

The conclusion is that skin and hair patterns are formed by a mix of cell activities, molecular signals, and environmental factors.

Organs like hair follicles can renew themselves in complex ways, adapting to different needs and environments.

Wounds can regenerate hair in young mice, but this ability declines with age, offering insights for improving tissue regeneration in the elderly.

A woman had hair loss, nail changes, and skin peeling after a COVID-19 infection, which got better on their own.

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.

A WNT10A gene mutation leads to ectodermal dysplasia by disrupting cell growth and differentiation.

R-spondins and their receptors help increase bone growth and may be used to treat bone loss diseases.

The document concludes that stem cells and their environments are crucial for skin and hair health and have potential for medical treatments.

Low-dose acitretin helps nail psoriasis, stem cells may treat scarring alopecia, Chinese men have lower baldness rates, lateral foldplasty is good for ingrown toenails, hair diameter helps diagnose female baldness, childhood trauma linked to alopecia areata, certain hair-weaving leads to scalp conditions in African American women, and new methods for hair research and understanding hair and sweat gland development were introduced.

Older adults commonly experience hair loss and nail disorders due to aging and health changes, affecting their quality of life.

The document concludes that treatments like oral anti-androgens, minoxidil, and topical spironolactone can be effective for hair loss in men and women.

Most vertebrates can regenerate skin, nails, and corneas, but only some can regenerate teeth and lenses.

Biotin effectively treats hair loss, skin, and nail issues without overdose risk.

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.

Scientists turned mouse stem cells into skin cells that can grow into skin layers and structures.

Gene network oscillations inside hair stem cells are key for hair growth regulation and could help treat hair loss.

Stem cells can rejuvenate skin, restore hair, and aid in wound healing.

Different ectodermal organs like hair and feathers regenerate differently, with specific stem cells and signals involved in their growth and response to the environment.

Researchers found a way to create cells from stem cells that act like human cells important for hair growth and could be used for hair regeneration treatments.

Skin aging is caused by stem cell damage and can potentially be delayed with treatments like antioxidants and stem cell therapy.

The conclusion is that Fgf18 and Tgf-ß signaling could be targeted for hair loss treatments.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

There are two types of stem cells in rodent hair follicles, each with different keratin proteins.

Skin's epithelial stem cells are crucial for repair and maintenance, and understanding them could improve treatments for skin problems.
