Planarian regeneration begins with a specific gene activation caused by injury, essential for healing and tissue regrowth.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Scientists have found a way to create hair follicles from skin cells of newborn mice, which can grow and cycle naturally when injected into adult mouse skin.

Antiandrogens like flutamide are effective in treating conditions like prostate cancer and hair loss, but there's a need for more potent versions. Understanding their structure can help develop better treatments.

Lactate production is important for activating hair growth stem cells.

The cuneate nucleus has two main neuron types: relay neurons and interneurons.

A gene called APCDD1, which controls hair growth, is found to be faulty in a type of hair loss called hereditary hypotrichosis simplex.

The hedgehog signaling pathway is crucial for hair growth but not for the initial creation of hair follicles.

Estrogens can improve skin aging but carry risks; more research is needed on safer treatments.

Alopecia areata is an autoimmune condition causing hair loss due to the immune system attacking hair follicles, often influenced by genetics and stress.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Flutamide is more effective and has fewer side effects than spironolactone for treating hirsutism.

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

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

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.

Tributyltin exposure causes sex changes, sterilization, and decline in the snail Ocinebrina aciculata, risking its extinction.

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

Too much androgen can cause hair loss; finasteride may help.

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

Young adults have about 230,000 tactile nerve fibers, decreasing 5-8% per decade with age.

Postpartum depression is linked to changes in brain chemicals, inflammation, stress, and certain genes, and can potentially be identified by markers like specific steroids, serotonin levels, and vitamin D levels.

Taxane chemotherapy can cause skin, hair, and nail side effects, which are often under-reported and can affect patient quality of life.

Sonic hedgehog signaling is crucial for hair growth and maintaining hair follicle identity.

Finasteride treats enlarged prostate and hair loss, but may cause side effects in some patients.

Adam10 enzyme is crucial for healthy skin and proper Notch signaling.

Modulating BMP activity changes the number, size, shape, and type of ectodermal organs.

Skin grafts on mice can cause an immune response leading to hair loss, useful for studying human hair loss conditions.

Mouse hair follicle cells briefly grow during the early hair growth phase, showing that these cells are important for starting the hair cycle.

Flutamide effectively reduced excessive hair growth and improved related symptoms in hirsutism patients without significant side effects.

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