Losing eyelashes or eyebrows can be a sign of many different health problems and needs a careful approach to treat effectively.

Different fish use the same genes to regrow teeth.

Epithelial stem cells can adapt and help in tissue repair and regeneration.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.

Research on epidermal stem cells has advanced significantly, showing promise for improved clinical therapies.

RANK is a key target in breast cancer treatment due to its role in tumor growth and bone metastasis.

The best way to treat acne is to prevent healthy skin glands from turning into acne lesions by controlling the triggers early on.

Scientists found cells in hair that are key for growth and color.

Stem cells have great potential for improving wound healing, but more research is needed to find the best types and ways to use them.

Barley extract, specifically procyanidin B-3, can promote hair growth and counteract growth inhibition.

Fully regenerating human hair follicles not yet achieved.

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

In vivo lineage labelling is better than in vitro methods for identifying and understanding stem cells.

An 8-year-old girl had a rare, benign skin tumor on her forehead.

Skin cancer often starts from Lgr5+ progenitor cells.

Phaeodactylum tricornutum extract helps hair follicle cells grow by activating the ERK1/2 pathway.

Procyanidin B-2 from apple juice significantly increases hair growth and may be more effective than minoxidil without side effects.

Cicatricial alopecia, a permanent hair loss condition, is mainly caused by damage to specific hair follicle stem cells and abnormal immune responses, with gene regulator PPAR-y and lipid metabolism disorders playing significant roles.

Hair follicle development is controlled by interactions between skin tissues and specific molecular signals.

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

Hair regeneration needs dynamic cell behavior and mesenchyme presence for stem cell activation.

The conclusion is that proper signaling is crucial for hair growth and development, and errors can lead to cancer or hair loss.

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.

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

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

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.

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.

EdnrB signaling helps melanocyte stem cells regenerate and could be targeted to treat pigmentation issues.

Teloptosis is a key point in hair loss that could help in creating prevention-focused hair care strategies.
