The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

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.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

The research identified various cell types in mouse and human teeth, which could help in developing dental regenerative treatments.

SHISA6 helps maintain certain stem cells in mouse testes by blocking signals that would otherwise cause them to differentiate.

MicroRNAs play a crucial role in skin and hair health, affecting everything from growth to aging, and could potentially be used in treating skin diseases.

Arctiin helps protect hair cells from damage and death caused by oxidative stress.

The androgen receptor is a promising target for breast cancer treatment, especially in triple-negative cases, but more research is needed for personalized therapies.

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

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.

Troxerutin helps protect skin cells from oxidative stress and may be good for treating hair loss.

Understanding and manipulating epigenetic changes can potentially lead to human organ regeneration therapies, but more research is needed to improve these methods and minimize risks.

Fish teeth and taste bud densities are linked and can change between types due to shared genetic and molecular factors.

Eating fewer calories improves the ability of stem cells to repair and renew the body in various tissues.

Using radiation to make mice's hair turn gray helps study and find ways to prevent or reverse hair graying.

The nucleus is key in controlling skin growth and repair by coordinating signals, gene regulators, and epigenetic changes.

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

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

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

Sox21 is crucial for tooth development and enamel formation by preventing cells from changing into a different type.

PTEN helps control the number and health of skin stem cells by working with the protein BMAL1.

Hair dye ingredient PPD causes cell death and aging in human hair cells by altering microRNA levels.

Low oxygen areas help maintain and protect blood stem cells by using a simple sugar breakdown process for energy and managing their activity levels.

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

Managing oxidative stress might help treat low testosterone and related chronic diseases in aging men.

OCT4 helps granulosa cell growth in early-stage follicles, and FSH increases OCT4 through specific pathways.

Transplanted hair follicle stem cells can heal damaged rat intestines.

Nrf-2-modified stem cells from hair follicles significantly improve ulcerative colitis in rats.

Mesenchymal stem cells could help treat aging-related diseases better than current methods.
