Hormone treatments in transsexual individuals reduce hair growth and oil production in male-to-females and increase them in female-to-males.

Scientists made working salivary glands in mice using bioengineered cells, which could help treat dry mouth.

CDP is crucial for lung and hair follicle cell development.

Memory T cells in the skin balance staying put and moving into the blood, clustering around hair follicles, and increasing in number after infection.

Stem cell self-renewal is complex and needs more research for full understanding.

Cathepsin L is essential for normal hair growth and development.

Aging causes skin stem cells to work less effectively.

Androgens, like testosterone, are crucial for early testicular descent in rats.

Keratose, derived from human hair, is a non-toxic biomaterial good for tissue regeneration and integrates well with body tissues.

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

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

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

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

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.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

Normal skin cell renewal doesn't need RAR signaling, but vitamin A-related skin thickening does.

Probiotic bacteria improved skin and hair health in aged mice.

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.

We need more research to better understand human hair follicle stem cells for improved treatments for hair loss and skin cancer.

Skin-derived precursors in hair follicles come from different origins but function similarly.

Laminin-511 is crucial for early hair growth and maintaining important hair development signals.

Fullerenes show potential in skin care but need more safety research.

New nanocomposites with copper show promise for healing burn wounds and regenerating skin.

Wnt signaling helps control how brain stem cells divide and is important for brain repair after injury.

Feather growth and regeneration involve complex patterns, stem cells, and evolutionary insights.

Skin development in mammals is controlled by key proteins and signals from underlying cells, involving stem cells for maintenance and repair.

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

Muscles and nerves that cause goosebumps also help control hair growth.
