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

Stem cell differentiation is crucial for skin barrier maintenance and its disruption can lead to skin diseases.

MicroRNA-148a is crucial for maintaining healthy skin and hair growth by affecting stem cell functions.

BLIMP1 is essential for skin maintenance but not for defining sebaceous gland progenitors.

Inhibiting class I HDACs helps maintain hair growth ability in skin cells.

Skin health and repair depend on the signals between skin stem cells and their surrounding cells.

Cells in hair follicles help create fat cells in the skin by releasing a protein called Sonic Hedgehog.

Cow blood vessel cell secretions helped heal rat burn wounds and may treat burns and hair loss.

Hair follicle stem cells use specific chromatin changes to control their growth and differentiation.

Chrysanthemum zawadskii extract helps hair grow by stimulating hair cells.

The document concludes that specific cells are essential for hair growth and more research is needed to understand how to maintain their hair-inducing properties.

Wnt proteins from certain skin cells are crucial for normal hair growth and renewal.

The Hairless gene is crucial for hair cell development, affecting whether skin cells become hair or skin and oil gland cells.

Adult esophageal cells can start to become like skin cells, with a key pathway influencing this change.

MicroRNA-205 helps hair grow by changing the stiffness and contraction of hair follicle cells.

The study found that sweat glands contain different types of stem cells that help with healing and maintaining healthy skin.

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

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.

Hormones during pregnancy and lactation keep skin stem cells inactive, preventing hair growth.

A protein called sFRP4 from skin cells stops the development of pigment-producing cells in hair.

Certain signals are important for reducing specific chemical markers on hair follicle stem cells during rest periods, which is necessary for healthy hair growth.

Both immature and mature fat cells are important for hair growth cycles, with immature cells promoting growth and mature cells possibly inhibiting it.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.

Removing vitamin D and calcium receptors in mice skin cells slows down skin wound healing.

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

Hair follicle regeneration and delivery is complex due to many molecular and cellular factors.

DNA methylation is essential for skin and hair follicle development, and could be a target for treating skin diseases.

Dogs could be good models for studying human hair growth and hair loss.
