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

Melatonin treatment helps improve skin health in postmenopausal rats.

Hair growth and development are controlled by specific signaling pathways.

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.

The Foxn1(-/-) nude mouse shows disrupted and expanded skin stem cell areas due to high Lhx2 levels.

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

Skin stem cells were turned into heart cells using a chemical, suggesting a new way to treat heart attacks.

CD4+ skin cells may be precursors to basal cell carcinoma.

Scientists can control how skin stem cells divide by using different treatments.

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

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

Vav2 and Vav3 proteins help control skin stem cell numbers and activity in both healthy and cancerous cells.

Epidermal stem cells have various roles in skin beyond just maintenance, including forming specialized structures and aiding in skin repair and regeneration.

Temporary ROS production in cultured human hair follicles promotes growth and stem cell activation.

Dermal EZH2 controls skin cell development and hair growth in mice.

Dermal EZH2 controls skin cell growth and differentiation in mice.

Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.

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

Lack of Ctip2 in skin cells delays wound healing and disrupts hair follicle stem cell markers in mice.

Stretching skin increases a certain protein that attracts stem cells, helping skin regeneration.

Notch1 signaling is crucial for improving wound healing and skin regeneration by affecting stem cell behavior.

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

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

The document concludes that understanding how adult stem and progenitor cells move is crucial for tissue repair and developing cell therapies.

Orobanche rapum extract rejuvenates skin and protects skin bacteria, leading to healthier skin.

Certain skin cells near the base of hair muscles may help renew and stabilize skin, possibly affecting skin disorder understanding.

Certain immune cells in the skin release a protein that stops hair growth by keeping hair stem cells inactive.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Research on epidermal stem cells has advanced significantly, showing promise for improved clinical therapies.

Blocking TSLP reduces skin inflammation and cell overgrowth in psoriasis.
