Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

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

Certain mature cells in mouse lungs can turn back into stem cells to aid in tissue repair.

Understanding phenotypic plasticity is crucial for developing effective cancer therapies.

Super-enhancers controlled by pioneer factors like SOX9 are crucial for stem cell adaptability and identity.

The research found that different types of fibroblasts are involved in wound healing and that some blood cells can turn into fat cells during this process.

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

The study found that sweat glands contain different types of stem cells that help with healing and maintaining healthy skin.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

Tofacitinib is safe and effective for severe alopecia areata, but hair loss may return 2 months after stopping treatment.

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 skin cells play specific roles in development, healing, and cancer.

PGD2 stops hair growth and is higher in bald men with AGA.

A gene called APCDD1, which controls hair growth, is found to be faulty in a type of hair loss called hereditary hypotrichosis simplex.

Ruxolitinib effectively regrows hair in most patients with severe hair loss.

Hair follicle stem cells use specific chromatin changes to control their growth and differentiation.

Different types of skin cells have unique genetic markers that affect how likely they are to spread cancer.

Wnt signaling controls whether hair follicle stem cells stay inactive or regenerate hair.

Blocking JAK-STAT signaling can lead to hair growth.

Aging causes skin stem cells to work less effectively.

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.

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

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.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

Mice hair growth patterns get more complex with age and can change with events like pregnancy or injury.

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

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

The research identified various cell types in mouse and human teeth, which could help in developing dental regenerative treatments.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.
