EZH2 levels decrease as fetuses develop and are higher in adult skin, which may affect skin growth and repair.

Human stem cells were turned into cells similar to those that help grow hair and showed potential for hair follicle formation.

Sweat gland development involves two unique skin cell programs and a temporary skin environment.

The patient has a rare skin condition that shows features of two known disorders.

Different fish use the same genes to regrow teeth.

HSD11b1 affects skin nerves and increases non-histaminergic itch.

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

Alopecia X in dogs is a cosmetic issue, not a hormonal disorder, and harmful treatments should be avoided.

Testosterone therapy can help postmenopausal women with low sexual desire but needs more safety research and should be used with estrogen therapy.

Testosterone therapy can help with androgen deficiency in women but should be used with caution and monitoring due to potential risks.

Androgens cause oil-producing skin cells with androgen receptors to mature and produce more oil.

Prdm1 is necessary for early whisker development in mice but not for other hair, and its absence changes nerve and brain patterns related to whiskers.

Mitochondrial dysfunction may contribute to chronic inflammation and immune system issues in Lichen planopilaris.

The study created hair-bearing skin models that lack a key protein for skin layer attachment, limiting their use for certain skin disease research.

The document concludes that it's important to recognize and treat hair loss in women of color, considering their unique hair characteristics and psychological impact.

Scientists successfully created mouse hair proteins in the lab, which are stable and similar to natural hair.

Different scaffold patterns improve wound healing and immune response in mouse skin, with aligned patterns being particularly effective.

Gelatin microspheres with stem cells speed up healing in diabetic wounds.

Eating fewer calories improves the ability of stem cells to repair and renew the body in various tissues.

Rural Bangladeshi girls mature later than peers in other low and middle-income countries due to poor nutrition and socioeconomic conditions.

Three dogs with a rare skin condition improved with treatment.

New regenerative therapies show promise for treating hair loss.

Mouse touch-sensitive nerve cells adjust their connections based on competition with other similar 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.

The document describes various skin conditions, their features, and treatments but lacks detailed study size information.

Black-tailed deer have four types of pelages and molt twice a year.

Sox21 is crucial for tooth development and enamel formation by preventing cells from changing into a different type.

RANKL causes lymph nodes to grow by making certain cells multiply.

CD34+ and CD34- melanocyte stem cells have different regenerative abilities.

Horizontal sections of scalp biopsies are good for diagnosing Central Centrifugal Cicatricial Alopecia and help customize treatment.
