Male and female skin differ due to hormones, affecting conditions like hair loss, acne, and skin cancer, and suggesting a need for gender-specific treatments.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

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

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

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.

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

Scientists created stem cells that can grow hair and skin.

Hormones and metabolism play a complex role in prostate enlargement, and more research is needed to improve diagnosis and treatment.

No treatment fully prevents hair loss from chemotherapy yet.

Newborn mouse skin cells can grow hair and this process can be recreated in adult cells to potentially help with hair loss.

Layer-by-Layer self-assembly is promising for biomedical uses like tissue engineering and cell therapy, but challenges remain in material safety and process optimization.

Mutations in Gasdermin A3 cause skin inflammation and hair loss by disrupting mitochondria.

Hair grays due to oxidative stress and fewer functioning melanocytes.

Short-chain fatty acids from *Cutibacterium acnes* cause skin inflammation, contributing to acne.

Melanocyte development from neural crest cells is complex and influenced by many factors, and better understanding could help treat skin disorders.

Compartmentalized organization might be crucial for stem cells to effectively respond to growth or injury.

The study showed that hair follicle stem cells can maintain and organize themselves in a lab setting, keeping their ability to renew and form hair and skin.

Certain signals and genes play a key role in hair growth and regeneration, and understanding these could lead to new treatments for skin regeneration.

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

Two-photon microscopy helps observe hair follicle stem cell behaviors in mice.

WNT10A helps esophageal cancer cells spread and keep renewing themselves.

Tcf3 helps cells move and heal wounds by controlling lipocalin 2.

Androgens prevent hair growth by changing Wnt signals in cells.

Some natural compounds may help overcome drug resistance in certain cancers, but more research is needed.

Activin B improves wound healing and hair growth by helping stem cells move using certain cell signals.

Macrophages are essential for successful skin growth in reconstructive surgery.

Researchers developed a 3D model of human hair follicle cells that can help understand hair growth and test new hair loss treatments.

Hair follicle regeneration possible, more research needed.

Mesenchymal stem cells help improve wound healing by reducing inflammation and promoting skin cell growth and movement.

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