Testosterone can both promote hair growth and cause baldness by affecting hair growth signals.

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

Most adrenal cortex tumors are benign and non-secreting, but proper diagnosis and treatment are important due to the rare possibility of cancer.

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.

Different ectodermal organs like hair and feathers regenerate differently, with specific stem cells and signals involved in their growth and response to the environment.

Lipase H is important for hair follicle function and shaping hair fibers.

Immune cells are crucial for hair growth and preventing hair loss.

Removing Sprouty genes in mice causes various hormone-related issues but does not increase cancer risk by one year of age.

Excess androgens may cause PCOS, not just be a symptom.

Certain long non-coding RNAs are important for controlling hair growth cycles in sheep.

The treatment was ineffective in humans.

The conclusion is that certain chemicals from Bacillus subtilis help improve plant root growth through a hormone-related process.

The SbbHLH85 protein helps sweet sorghum grow more root hairs but makes the plant more sensitive to salt.

Dermal EZH2 controls skin cell growth and differentiation in mice.

Researchers found that certain RNA sequences play a role in yak hair growth and these sequences are somewhat similar to those in cashmere goats.

Nanoparticle-based herbal remedies could be promising for treating hair loss with fewer side effects and lower cost, but more research is needed.

Certain small molecules can help regrow hair by turning on the body's cell cleanup process.

The document concludes that various topical treatments show promise for skin conditions like atopic dermatitis, psoriasis, and hair loss.

SM04755 may be an effective topical treatment for psoriasis.

The document concludes that Cutaneous Lupus Erythematosus has different forms, is influenced by genetic and environmental factors, and can be treated with various medications, but more targeted therapies are needed.

DHT reduces a cell's ability to promote hair growth, while 3D culture without DHT improves it.

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

Scientists found key proteins and genes that affect skin and hair health, and identified potential new treatments for hair loss, skin disorders, and wound healing.

The Hairless gene is crucial for healthy skin and hair growth.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

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

The Wnt/β-catenin pathway helps tissue regeneration but can also cause fibrosis, and drugs that inhibit this pathway may aid in healing skin and heart tissues.

The Wnt/β-catenin pathway is important for tissue development and has potential in regenerative medicine, but requires more research for therapeutic use.

Keratin 15 is not a reliable sole marker for identifying epidermal stem cells because it's found in various cell types.

Keratinocytes control how melanocytes work.
