Hair ages and thins due to factors like inflammation and stress, and treatments like antioxidants and hormones might improve hair health.

Recognizing and treating skin symptoms in essential thrombocythemia is crucial for patient quality of life.

Regenerated fully functional hair follicles using stem cells, with potential for hair regrowth therapy.

The document concludes that while some organisms can regenerate body parts, mammals generally cannot, and cancer progression is complex, involving mutations rather than a strict stem cell hierarchy.

The conclusion is that proper signaling is crucial for hair growth and development, and errors can lead to cancer or hair loss.

Stromal stem cells may help heal wounds by becoming structural cells or affecting the immune system, but more research is needed to understand how.

Nuclear hormone receptors play a significant role in skin wound healing and could lead to better treatment methods.

The skin systems of jawed vertebrates evolved diverse appendages like hair and scales from a common structure over 420 million years ago.

Ephrins slow down skin and hair follicle cell growth.

Activating TLR9 helps heal wounds and regrow hair by using specific immune cells.

Skin organoids help improve wound healing and tissue repair.

Teens with PCOS and a mom with PCOS have higher insulin resistance and lower adiponectin levels, which could signal early metabolic problems.

Mice lacking steroid 5α-reductase 2 show less aggression and better impulse control.

Adipose-derived stem cells show promise in treating skin conditions like vitiligo, alopecia, and nonhealing wounds.

Hair follicle development is controlled by interactions between skin tissues and specific molecular signals.

Androgen receptor activity blocks Wnt/β-catenin signaling, affecting hair growth and skin cell balance.

Hair and skin healing involve complex cell interactions controlled by specific molecules and pathways, and hair follicle cells can help repair skin wounds.

Psoriasis lesions have fewer and smaller oil glands, which might affect the condition's development.

Certain cells in the adult mouse ear come from cranial neural crest cells, but muscle and hair cells do not.

Antigen presenting cells around hair follicles are crucial in SLE-related hair loss.

Engineered skin substitutes can grow hair but have limitations like missing sebaceous glands and hair not breaking through the skin naturally.

Cannabinoid receptor-1 signaling is essential for the survival and growth of human hair follicle stem cells.

Certain RNA molecules are important for the development of wool follicles in sheep.

Human fetal placental stromal cell injections speed up healing and improve skin and hair recovery after radiation damage.

Retinoic acid-binding proteins in skin are regulated by β-catenin and Notch signalling.

Chicken feather gene mutation helps understand human hair disorders.

Androgen receptors are key for development and health, affecting conditions like prostate cancer and male pattern baldness.

The JAK/STAT pathway is important in cell processes and disease, and JAK inhibitors are promising for treating related conditions.
