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.

Human hair keratins can self-assemble and support cell growth, useful for biomedical applications.

Increasing Rps14 helps grow more inner ear cells and repair hearing cells in baby mice.

Mesenchymal stem cells show promise for effective skin repair and regeneration.

New cells are added to the hair's dermal papilla during the active growth phase.

Maintaining DNA health in stem cells is key to preventing aging and tissue breakdown.

Chick embryo extract helps rat hair follicle stem cells potentially turn into Schwann cells, important for the nervous system.

High levels of ERK activity are key for tissue regeneration in spiny mice, and activating ERK can potentially redirect scar-forming healing towards regenerative healing in mammals.

Special particles from umbilical cord stem cells help heal skin wounds in diabetic mice by preventing certain immune cell death.

Sensory neuron changes and Merkel-cell changes in the skin happen independently during normal skin maintenance.

Sebaceous glands can help harvest hair follicle stem cells to regenerate skin and hair.

Blue-light activation of TrkA improves hair-follicle stem cells' ability to become neurons and glial cells.

Using patients' own fat-derived cells to treat alopecia areata significantly improved hair growth and was safe.

The protein folliculin, involved in a rare disease, works with another protein to control how cells stick together and their organization, and changes in this interaction can lead to disease symptoms.

The plant extract remedy Satura® Rosta promotes hair growth and regrowth without negative effects.

Researchers found four key stages of cell development that are important for hair growth and shedding in cashmere goats.

Quercetin significantly helps hair growth by activating hair follicles and improving blood vessel formation around them.

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

Elastin-like recombinamers show promise for better wound healing and skin regeneration.

Skin aging is caused by stem cell damage and can potentially be delayed with treatments like antioxidants and stem cell therapy.

Removing Dicer from pigment cells in newborn mice causes early hair graying and changes in cell migration molecules.

Merkel cells stabilize nerve endings in the skin, and they change independently of each other.

Activating β-catenin increases melanocytes and decreases Schwann cells.

Certain cells from hair follicles can create new hair and contribute to hair growth when implanted in mice.

A specific RNA molecule, circCOL1A1, affects the growth and quality of goat hair by interacting with miR-149-5p and influencing cell growth pathways.

Skin's epithelial stem cells are crucial for repair and maintenance, and understanding them could improve treatments for skin problems.

Hair thinning causes stem cell loss through a process involving Piezo1, calcium, and TNF-α.

Dihydrotestosterone treatment on 2D and 3D-cultured skin cells slows down hair growth by affecting certain genes and could be a potential target for hair loss treatment.

Older people's sweat glands are less effective at helping skin wounds heal due to weaker cell connections.
