Activating β-catenin in different skin stem cells causes various types of hair growth and skin tumors.

Glutamine metabolism affects hair stem cell maintenance and their ability to change back to stem cells.

NAC1 controls certain enzymes that reduce root hair growth in Arabidopsis.

Scientists made working salivary glands in mice using bioengineered cells, which could help treat dry mouth.

Fat cells in the skin help start healing and form important repair cells after injury.

White lupin uses specific genes to grow root hairs and access phosphorus when it's scarce.

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

Live imaging has advanced our understanding of stem cell behavior and raised new research questions.

Isoproterenol helps hair follicle stem cells turn into beating heart muscle cells.

NF-κB is crucial for different stages and types of hair growth in mice.

Cat color patterns are determined early in development by gene expression and epidermal changes, with the Dickkopf 4 gene playing a crucial role.

The study found stem cells in minor salivary glands that can differentiate and are involved in tumor formation when exposed to tobacco.

The HOXC13 gene affects different hair proteins in cashmere goats in varied ways and is controlled by a feedback loop and other factors.

KLF4 is important for maintaining stem cells and has potential in cancer treatment and wound healing.

Mechanical forces are crucial for shaping cells and forming tissues during development.

Eating less can improve stem cell function and increase lifespan.

Wounded skin cells can revert to stem cells and help heal.

Different hair follicles in the skin are innervated by unique combinations of mechanosensory neurons, crucial for touch sensation.

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

Advancements in nanoformulations for CRISPR-Cas9 genome editing can respond to specific triggers for controlled gene editing, showing promise in treating incurable diseases, but challenges like precision and system design complexity still need to be addressed.

The review concludes that innovations in regenerative medicine, tissue engineering, and developmental biology are essential for effective tissue repair and organ transplants.

White blood cells and their traps can slow down the process of new hair growth after a wound.

Bird foot scales develop differently and can repair but not fully regenerate due to the lack of specialized stem cell areas.

Mechanical force is important for the first contact between skin cells and hair growth in mini-organs.

Hair follicle stem cells can turn into many cell types and may help repair nerve damage and have other medical uses.

Skin cancer often starts from Lgr5+ progenitor cells.

SOX2 is crucial for skin cell function and hair growth, and it plays a role in skin cancer and wound healing.

Fisetin, a type of polyphenol, may help hair grow by increasing certain protein activities in cells.

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.

Pigs without the Hairless gene showed skin and thymus changes, useful for studying human hair disorders.
