Aging changes hair stem cells and their environment, leading to gray hair and hair thinning, but understanding these changes could help develop treatments for hair regeneration.

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

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.

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

Changing the environment around stem cells could help tissue repair, but it's hard to be precise and avoid side effects.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Epidermal stem cells are diverse and vary in activity, playing key roles in skin maintenance and 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.

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

Ruxolitinib helps protect skin stem cells and keeps skin healthy in mice with skin GVHD.

PTEN helps control the number and health of skin stem cells by working with the protein BMAL1.

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

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

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

Skin healing from blisters can delay hair growth as stem cells focus on repairing skin over developing hair.

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.

Using the drugs AMD3100 and Tacrolimus together greatly improves skin healing and hair growth after a deep skin cut by increasing stem cells in the wound.

Peptide hydrogel scaffolds help grow new hair follicles using stem cells.

The protein SLC1A3 is important for activating skin stem cells and is necessary for normal hair and skin growth in mice.

Hair follicle stem cells help maintain skin health and could improve skin replacement therapies.

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

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

Lactate production is important for activating hair growth stem cells.

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

Scientists created hair-growing skin models from stem cells, which could help treat hair loss and skin diseases.

The Msi2 protein helps keep hair follicle stem cells inactive, controlling hair growth and regeneration.

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

Overexpression of sPLA2-IIA in mouse skin reduces hair stem cells and increases cell differentiation through JNK/c-Jun pathway activation.

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