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

Epigenetic and metabolic changes affect stem cell function and aging in skin.

Vitamin A helps skin stem cells decide their function, aiding in hair growth and wound repair.

Different signals work together to change gene activity and guide hair follicle stem cells to become specific cell types.

Touch dome keratinocytes in adult skin have traits of different skin cell types.

Lgr5 and the vitamin D receptor are key in controlling skin inflammation and tumor risk in mice.

Lanceolate complexes in mouse hair follicles are essential for touch and depend on specific cells for maintenance and regeneration.

Tissue stem cells originate from specific areas in organs and are vital for organ maintenance and repair.

Hair follicle stem cells can return to their original niche and help regenerate hair.

Adult tissue stem cells can adapt and switch roles to help repair and maintain the body.

Blocking certain immune signals can reduce skin damage from radiation therapy.

Paneth cells help support stem cells and aid tissue regeneration after injury.

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

Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

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

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.

Nail stem cells and Wnt signaling are important for fingertip regeneration but not sufficient for regenerating more complex limb structures.

Eating less can improve stem cell function and increase lifespan.

ATP-dependent chromatin remodeling is crucial for skin development and stem cell function.

Autophagy helps control skin inflammation and cancer responses and regulates hair growth by affecting stem cell activity.

MEX3A is crucial for maintaining intestinal stem cells in mice.

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

HDAC1 is crucial for skin development and preventing tumors.

The study created a mouse model to better understand hair follicle stem cells' role in hair growth and repair.

GDNF helps grow hair and heal skin wounds by acting on hair stem cells.

Stem cells in the cornea show unexpected flexibility and have important implications for medicine.

Different types of stem cells and their environments are key to skin repair and maintenance.

The pituitary gland functions normally even after losing most SOX2+ stem cells.

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