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

Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

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.

The Wnt/β-catenin pathway helps tissue regeneration but can also cause fibrosis, and drugs that inhibit this pathway may aid in healing skin and heart tissues.

The skin protects the body and is constantly renewed by stem cells; disruptions can lead to cancer.

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

Researchers created a fully functional, bioengineered skin system with hair from stem cells that successfully integrated when transplanted into mice.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

The study showed that hair follicle stem cells can maintain and organize themselves in a lab setting, keeping their ability to renew and form hair and skin.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

Macrophages help hair growth after injury through CX3CR1 and TGF-β1.

Cavity macrophages gather on organ surfaces but don't really invade or help repair the organs after injury.

Blocking TSLP reduces skin inflammation and cell overgrowth in psoriasis.

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

Two-photon microscopy effectively tracks live stem cell activity in mouse skin with minimal harm and clear images.

Hair and skin can regenerate without bulge stem cells due to other compensating cells.

Stem cells rearrangement regenerates functional hair follicles, potentially treating hair loss.

Removing integrin α3β1 from hair stem cells lowers skin tumor growth by affecting CCN2 protein levels.

Stem cells help remove dead cells to keep tissues healthy by balancing cell replacement and clearance.

Eating less can improve stem cell function and increase lifespan.

CD4+ skin cells may be precursors to basal cell carcinoma.

Different types of fibroblasts play specific roles in wound healing and cancer, which could help improve treatments.

Different fish use the same genes to regrow teeth.

Scientists made working hair follicles using stem cells, helping future hair loss treatments.

Dermal stem cells help regenerate hair follicles and heal skin wounds.

Different types of stem cells help maintain and heal skin.

Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.

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