Special gut cells help stem cells move to and fix injured areas by activating a specific signaling pathway.

Fibroblasts, cells usually linked to tissue repair, also help regenerate various organs and their ability decreases with age. Turning adult fibroblasts back to a younger state could be a new treatment approach.

Metabolism plays a key role in determining stem cell fate.

Understanding how epigenetic regulation affects stem cells is key to cancer insights and new treatments.

Humans have limited regenerative abilities, but new evidence shows the adult brain and heart can regenerate, and future treatments may improve this by mimicking stem cell environments.

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

Stem cell offspring help control their parent stem cells, affecting tissue health, healing, and cancer.

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

Calcium is important for stem cell function and maintenance, especially in blood and skin cells.

Eating less can improve stem cell function and increase lifespan.

Metabolic signals and cell shape influence how cells develop and change.

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

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

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

Certain immune system proteins are important for skin healing but can cause problems if there are too many of them.

Proper control of β-catenin activity is crucial for development and preventing diseases like cancer.

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.

Stem cell self-renewal is complex and needs more research for full understanding.

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

Some stem cells in the body rarely divide, which could help create better treatments for diseases and aging.

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

Scientists created a new 3D skin model from cells of plucked hairs that works like real skin and is easier to get.

Epigenetic changes control how adult stem cells work and can lead to diseases like cancer if they go wrong.

Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.

Eating less can slow aging and help keep stem cells healthy by cleaning out damaged cell parts.

Vitamin D and calcium are important for quick and effective skin wound healing.

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

The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.

Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.

Patients with myotonic dystrophy often have skin problems that suggest early aging and vitamin D issues, and the severity of these problems is linked to their genetic condition and vitamin D levels.
