Different signals work together to change gene activity and guide hair follicle stem cells to become specific cell types.

Key genes can rewire networks, changing skin appendage types.

The skin's microbiome helps hair regrow by boosting certain cell signals and metabolism.

Human prenatal skin develops an immune network early on that helps with skin formation and healing without scarring.

Sebaceous glands can heal and regenerate after injury using their own stem cells and help from hair follicle cells.

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.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

Four genes are potential markers for hair loss condition alopecia areata, linked to a specific type of cell death.

Follistatin and LIN28B together improve the ability of inner ear cells in mice to regenerate into hearing cells.

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

Autophagy helps delay aging in mouse glands, maintains fat balance, and controls scent production.

TSLP affects atopic dermatitis by increasing sebum and reducing fat through IL-4/IL-13 signaling.

IL-24 contributes to skin aging by increasing collagen-degrading enzymes and decreasing collagen production when exposed to air pollution.

Hair loss in Androgenetic Alopecia is caused by genetics, aging, and lifestyle, leading to hair follicle shrinkage and related health risks.

Rhamnose may help hair growth and pigmentation, making it a potential treatment for hair loss.

BRG1 is essential for skin cells to move and heal wounds properly.

White blood cells and their traps can slow down the process of new hair growth after a wound.

Hair growth can be stimulated by combining certain skin cells, which can rejuvenate old cells and cause them to specialize in hair follicle creation.

Autophagy helps control skin inflammation and cancer responses and regulates hair growth by affecting stem cell activity.

The PIP5K1A gene helps cashmere growth in goats by promoting cell proliferation, and melatonin boosts its expression.

Researchers found a specific immune receptor in patients that causes severe skin reactions to a drug.

Skin organoids from stem cells can help study and treat skin issues but face some challenges.

Mechanical forces are crucial for shaping cells and forming tissues during development.

Shi-Bi-Man activates hair follicle stem cells and promotes hair growth by changing lactic acid metabolism and other cellular processes.

Arrector pili muscle regulates hair follicle stem cells, DNA methylation needed for hair cycling, and Wnt/B-catenin signaling starts hair growth.

A specific hair protein variant increases the spread of breast cancer and is linked to worse survival rates.

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

Long COVID causes various long-term health issues and needs better awareness and treatment.

Cells lacking the Bax protein can outcompete others, leading to better tissue repair and hair growth.

Fat cells in the skin help start healing and form important repair cells after injury.
