Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.

TGF-β2 helps activate hair follicle stem cells by counteracting BMP signals.

Increasing miR-149 reduces hair follicle stem cell growth and hair development by affecting certain cell growth pathways.

Lipocalin-Type Prostaglandin D2 Synthase (L-PGDS) is a protein that plays many roles in the body, including sleep regulation, pain management, food intake, and protection against harmful substances. It also affects fat metabolism, glucose intolerance, cell maturation, and is involved in various diseases like diabetes, cancer, and arthritis. It can influence sex organ development and embryonic cell differentiation, and its levels can be used as a diagnostic marker for certain conditions.

The conclusion is that understanding how hair follicle stem cells live or die is important for maintaining healthy tissue and repairing injuries, and could help treat hair loss, but there are still challenges to overcome.

The study found new details about human hair growth and suggests that preventing a specific biological pathway could potentially treat hair graying.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

Different types of inactive melanocyte stem cells exist with unique characteristics and potential to develop into other cells.

The nude gene causes skin cell overgrowth and improper development, leading to hair and urinary issues.

Low-Level Laser Therapy can stimulate healing and cell function, potentially leading to wider medical use.

The congress highlighted new gene therapy techniques and cell transplantation methods for treating diseases.

Scientists found cells in hair that are key for growth and color.

Jumonji genes are important for development and their mutations can cause abnormalities, especially in the heart and brain.

Fibroblasts, cells usually linked to tissue repair, also help regenerate various organs and their ability decreases with age. Turning adult fibroblasts back to a younger state could be a new treatment approach.

The article concludes that while we understand a lot about how melanocytes age and how this can prevent cancer, there are still unanswered questions about certain pathways and genes involved.

Skin stem cells are crucial for maintaining and repairing skin, with potential for treating skin disorders and improving wound healing.

TGF-β is crucial for tissue repair and can cause diseases if not properly regulated.

Vitamin D has potential benefits for cancer prevention, heart health, diabetes, obesity, muscle function, skin health, and immune function, but clinical results are mixed and more research is needed.

Ginseng may help treat cancer and reduce treatment side effects, but more research is needed.

Visible light can damage skin and most sunscreens don't block it well; more research is needed on its effects and protection methods.

Cells in hair follicles help create fat cells in the skin by releasing a protein called Sonic Hedgehog.

Different types of resting melanocyte stem cells have unique characteristics and vary in their potential to become other cells.

Certain natural products may help stimulate hair growth by affecting stem cell activity in the scalp.

As skin cells mature, vitamin D receptor levels decrease while retinoid X receptor α levels increase.

Notch signalling helps skin cells differentiate and prevents tumors.

New therapies are being developed that target integrin pathways to treat various diseases.

The study concludes that regulating apoptosis could lead to new treatments for various skin and hair conditions.

Epidermal stem cells show promise for treating orthopedic injuries and diseases.

Early development of hair, teeth, and glands involves specific signaling pathways and cellular interactions.

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