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

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

The document concludes that the exact way alcohol causes harm to fetal development is unknown, but it significantly affects nutrient transport to the fetus and a safe level of alcohol during pregnancy is not determined.

Stem cell niches support, regulate, and coordinate stem cell functions.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

The WNT signaling pathway is important in many diseases and targeting it could offer new treatments.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Gene therapy with the Math1 gene helped regenerate balance-related cells and improve balance in mice.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

TRP channels in the skin are important for sensation and health, and targeting them could help treat skin disorders.

Different PIN proteins affect plant root hair growth by changing how auxin is transported.

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.

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

Animals that change color with the seasons mainly do so in response to daylight changes, but climate change is causing camouflage problems that may require evolutionary changes.

Blocking the Wnt pathway could lead to new treatments for cancer and tissue repair but requires careful development to avoid side effects.

Hair, teeth, and mammary glands develop similarly at first but use different genes later.

Hormones like estrogen, testosterone, progesterone, and prolactin play complex roles in female sexual function, with testosterone potentially improving sexual desire, arousal, and satisfaction. However, more research is needed to establish safe and effective hormone treatments for female sexual dysfunction.

No treatment fully prevents hair loss from chemotherapy yet.

The article concludes that better understanding gene regulation related to seasonal changes can offer insights into the mechanisms of seasonal timing in mammals.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.

Drosha and Dicer are essential for hair follicle health and preventing DNA damage in skin cells.

EGF and KGF signalling prevent hair follicle formation and promote skin cell development in mice.

A new gene, JMJD1C, may affect testosterone levels in men.

Dermal Papilla cells are a promising tool for evaluating hair growth treatments.

Progress has been made in skin and nerve regeneration, but more research is needed to improve methods and ensure safety.

Exosomes from dermal papilla cells help hair growth by making hair follicle stem cells multiply and change.

Blocking a specific enzyme might help treat obesity and diabetes, but more research is needed to ensure it's safe.
