Stem cells regenerate tissues and their behavior varies by environment, suggesting the hematopoietic system model may need revision.

Artificial dermal template treatment can stimulate complete skin and hair follicle regrowth.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

Lgr5 is a marker for active, self-renewing stem cells in the intestine and skin, important for tissue maintenance.

The protein interleukin-1 alpha helps regenerate hair follicles and increase stem cell growth in mice.

Skin cancer often starts from Lgr5+ progenitor cells.

LGR5 and LGR6 are expressed differently in various skin tumors, which may offer clues about their origins.

The document concluded that stem cells are crucial for skin repair, regeneration, and may help in developing advanced skin substitutes.

LGR5 helps maintain corneal cell characteristics and prevents unwanted changes by controlling specific cell signaling pathways.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

LGR5 is a common marker of hair follicle stem cells in different animals and is important for hair growth and regeneration.

A small group of slow-growing cells causes basal cell carcinoma to return after treatment.

High LGR5 levels in glioblastoma indicate poor prognosis and are essential for cancer stem cell survival.

CD61 is important for mouse tooth cell growth and works through Lgr5.

Blood-derived CD34+ cells speed up healing, reduce scarring, and regrow hair in skin wounds.

Inactive stem cells in hair follicles and muscles can avoid detection by the immune system.

The research found that different types of fibroblasts are involved in wound healing and that some blood cells can turn into fat cells during this process.

Krt15+ cells in the mouse intestine resist radiation and can start tumors.

Certain transcription factors are key in controlling skin stem cell behavior and could impact future treatments for skin repair and hair loss.

Hair follicle stem cells from Arbas Cashmere goats can become fat, nerve, and liver cells.

Ephrins slow down skin and hair follicle cell growth.

The document concludes that stem cell inactivity is actively controlled and important for tissue repair and balance.

Researchers found four genes that could help diagnose severe alopecia areata early.

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

Understanding where cancer cells come from helps create better prevention and treatment methods.

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.

Different small areas within hair follicles send specific signals that control what type of cells stem cells become.

Follistatin and LIN28B together improve the ability of inner ear cells in mice to regenerate into hearing cells.

Keratin injections can promote hair growth by affecting hair-forming cells and tissue development.

Dogs could be good models for studying human hair growth and hair loss.
