A woman's severe hirsutism was caused by Leydig cell tumors in her ovaries, which improved after surgery.

ATP-dependent chromatin remodeling is crucial for skin development and stem cell function.

The conclusion is that grasping how cells determine their roles through evolution is key, with expected progress from new research models and genome editing.

Live imaging has advanced our understanding of stem cell behavior and raised new research questions.

Cells from a skin condition can create new hair follicles and similar growths in mice, and a specific treatment can reduce these effects.

Cells communicate with neighbors to coordinate their development.

Understanding how epigenetic regulation affects stem cells is key to cancer insights and new treatments.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

The secretions of mesenchymal stem cells could be used for healing without using the cells themselves.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

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

BAY 43-9006 helps control kidney cancer growth but doesn't significantly increase overall survival.

Epigenetic changes control how adult stem cells work and can lead to diseases like cancer if they go wrong.

Hair stem cell regeneration is controlled by signals that can explain different hair growth patterns and baldness.

Epidermal stem cells are diverse and vary in activity, playing key roles in skin maintenance and repair.

Scientists found a new, less invasive way to study body clocks using hair cells, which shows shift workers' body clocks don't match their lifestyles.

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.

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

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

Myc changes chromatin in stem cells, causing them to leave their niche.

Conditioned media from mesenchymal stem cell cultures could be a more effective alternative for regenerative therapies, but more research is needed.

Circadian rhythms are crucial for stem cell function and tissue repair, and understanding them may improve aging and regeneration treatments.

Lichen Planopilaris and Frontal Fibrosing Alopecia may help us understand hair follicle stem cell disorders and suggest new treatments.

Oncogenic melanocyte stem cells can develop into melanoma similar to human cases.

The gene Foxq1, controlled by Hoxc13, is crucial for hair follicle differentiation.

Light can turn on hair growth cells through a nerve path starting in the eyes.

Beta-catenin is crucial for skin cell growth, development, and cancer formation.

Lef1 helps stem cells become hair cells by interacting with specific signaling pathways.

Tcf3 helps cells move and heal wounds by controlling lipocalin 2.

Overactive sonic hedgehog signaling worsens uterine scarring by reducing cell recycling.
