Male hair loss is caused by inactive hair follicle stem cells.

Men with baldness due to androgenetic alopecia still have hair stem cells, but lack specific cells needed for hair growth.

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 and their environments are key to skin repair and maintenance.

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.

Compartmentalized organization might be crucial for stem cells to effectively respond to growth or injury.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

Stem cells can help other stem cells by producing supportive factors.

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

Skin stem cells can help improve skin repair and regeneration.

Circular RNA ERCC6 helps activate stem cells important for cashmere goat hair growth by interacting with specific molecules in an m6A modification-dependent way.

Disrupted cholesterol production impairs hair follicle stem cells, leading to hair loss.

The exact identity of skin stem cells and how skin cells differentiate is not fully known.

Hair follicle stem cells can form both hair follicles and skin.

Low oxygen areas help maintain and protect blood stem cells by using a simple sugar breakdown process for energy and managing their activity levels.

Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.

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

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

Understanding how hair follicle stem cells work can help find new ways to prevent hair loss and promote hair growth.

Alpinetin helps grow hair by turning on hair stem cells and is safe for use.

Lack of Crif1 in hair follicle stem cells slows down hair growth in mice.

The study found that stem cells and neutrophils are important for regenerating hair follicle structures in mice.

The conclusion is that the cornea has two types of stem cells, with Lrig1+ cells being key for renewal in aging corneas, independent of CD44.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

The circadian clock affects skin stem cell behavior, impacting aging and cancer risk.

Skin can heal wounds without hair follicle stem cells, but it takes a bit longer.

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

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

The document concludes that adult mammalian skin contains multiple stem cell populations with specific markers, important for understanding skin regeneration and related conditions.

The HR protein's role as a repressor is essential for controlling hair growth.
