Mammalian organs regenerate using stem cells and cell plasticity, but this ability declines with age.

Deleting Twist1 in skin cells reduces UVB-induced skin cancer risk.

Researchers created rat liver stem cells that could help repair liver failure in rats and may be useful for studying human liver diseases.

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

Imaging intestinal stem cells might help detect early signs of colorectal cancer.

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.

Ephrins slow down skin and hair follicle cell growth.

Blood-derived CD34+ cells speed up healing, reduce scarring, and regrow hair in skin wounds.

Mouse hair follicle stem cells lose their ability to change into different cell types after being grown for a long time.

Human hair follicle stem cells show signs of low oxygen levels, which may be important for hair growth and preventing baldness.

A new method was developed to efficiently grow skin hair follicles from stem cells, potentially aiding alopecia treatment.

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.

Different types of long-lasting stem cells are responsible for the growth and upkeep of the mammary gland.

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

Stem cell offspring help control their parent stem cells, affecting tissue health, healing, and cancer.

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

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

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.

Stem cells are crucial for tissue growth, cancer treatment, and disease modeling, but challenges remain in clinical use.

Hair follicle stem cells are a promising source for tissue repair and treating skin or hair diseases.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

miR-22 helps skin cancer grow and spread by activating specific cell signals.

Some stem cells in the body rarely divide, which could help create better treatments for diseases and aging.

Proper control of β-catenin activity is crucial for development and preventing diseases like cancer.

Stem cell therapy could help regenerate inner ear hair cells to treat hearing loss.

Inflammation plays a key role in activating skin stem cells for hair growth and wound healing, but more research is needed to understand how it directs cell behavior.

Bioluminescence imaging can track hair follicle cells and help study hair regrowth.

Stem cells are more dynamic and adaptable than previously believed.
