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

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

Scarring alopecia affects different hair follicle stem cells than nonscarring alopecia, and the infundibular region could be a new treatment target.

The study found that bioengineered hair follicles work when using cells from the same species but have issues when combining human and mouse cells.

Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

Fat cells are important for tissue repair and stem cell support in various body parts.

PDGF signaling is crucial for maintaining and renewing hair follicle stem cells, which could help treat hair loss.

Wnt/ß-catenin signaling is crucial for regulating skin stem cells and hair growth, with the right levels and timing needed for proper function.

Different markers are found in stem cells of the scalp's hair follicle bulge and the surrounding skin.

Further research is needed to improve hair regeneration using stem cells and nanomaterials.

The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.

A hydrogel made from pig fat helps wounds heal faster by regenerating skin fat cells.

Eating less can slow aging and help keep stem cells healthy by cleaning out damaged cell parts.

High-dose radiation speeds up aging in skin stem cells.

Human body's immune cells are more common in the layer of fat just beneath the skin than in deeper fat layers.

In vivo lineage labelling is better than in vitro methods for identifying and understanding stem cells.

A circular RNA helps cashmere goat hair cells become hair follicles by blocking a molecule to boost a gene important for hair growth.

Hair growth environment recreated with challenges; stem cells make successful skin organoids.

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

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

Adipocytes can change into fibroblast-like cells to help with wound healing.

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

Immune cells are essential for early hair and skin development and healing.

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

New treatments for hair loss show promise, including plasma, stem cells, and hair-stimulating complexes, but more research is needed to fully understand them.

Activating Wnt in skin cells controls the number of hair follicles by directing cell movement and fate.

The conclusion is that the nuclear lamina and LINC complex in skin cells respond to mechanical signals, affecting gene expression and cell differentiation, which is important for skin health and can impact skin diseases.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

Lactate production is important for activating hair growth stem cells.

Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.
