Bone Morphogenetic Proteins (BMPs) help control skin health, hair growth, and color, and could potentially be used to treat skin and hair disorders.

Capsaicin, found in chili peppers, can slow down hair growth by affecting skin cells and hair follicles.

Pectin biosynthesis is essential for the growth of cotton fibers and Arabidopsis root hairs.

Blocking COX, especially COX-2, in the skin can reduce inflammation and pain and may help prevent skin cancer.

CDP is crucial for lung and hair follicle cell development.

Vitamin D and its receptor regulate skin functions like cell growth, immunity, hair cycle, and tumor prevention.

Androgens can cause hair growth in some areas and hair loss on the scalp.

Tight junctions are key for skin protection and controlling what gets absorbed or passes through the skin.

The dermal papilla is crucial for hair growth and health, and understanding it could lead to new hair loss treatments.

Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.

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

Understanding hair follicle anatomy helps diagnose hair disorders.

Masculine facial features may not reliably indicate heritable health, and more research is needed.

Different types of stem cells and their environments are key to skin repair and maintenance.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

The conclusion is that Treg-targeted therapies have potential, but more knowledge of Treg biology is needed for effective treatments, including for cancer.

Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.

Mouse hair follicle cells briefly grow during the early hair growth phase, showing that these cells are important for starting the hair cycle.

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.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

Stress can stop hair growth in mice, and treatments can reverse this effect.

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

Eclipta alba extract may help hair grow similarly to Minoxidil.

Understanding how cells die in the skin is important for treating skin diseases and preventing hair loss.

The article concludes that the wool follicle is a valuable model for studying tissue interactions and has potential for genetic improvements in wool production.

Most youth with gender dysphoria received hormones, had minor complications, and showed a decrease in suicide attempts after treatment.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

Hair loss occurs due to fewer papillary cells, smaller follicles, and shorter growth phases.

Stress increases nerve fibers and immune cell activity in mouse skin, possibly worsening skin conditions.

Men, especially older ones with health issues like prostate cancer, may have worse COVID-19 outcomes and could benefit from therapies targeting male hormones.
