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

Artificial skin development has challenges, but new materials and understanding cell behavior could improve tissue repair. Also, certain growth factors and hydrogel technology show promise for advanced skin replacement therapies.

WNT10A mutations often cause ectodermal dysplasias, with males showing more tooth issues than females.

Women with PCOS are more likely to have impaired glucose tolerance and type 2 diabetes, especially if they are Asian or obese.

Certain mutations in a hair growth-related gene cause a type of genetic hair loss.

Hair loss affects self-esteem and quality of life; treatments can help.

Jumonji genes are important for development and their mutations can cause abnormalities, especially in the heart and brain.

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

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Hair loss can significantly affect a person's self-esteem and body image, especially in young people, those who value their looks highly, and women.

Human dermal fibroblasts are the main cells targeted by a virus that can cause a deadly skin cancer, and a certain inhibitor can effectively block this infection.

Microneedles help improve skin appearance and deliver skin treatments effectively, but safety concerns need more research and regulation.

Forehead modification greatly increases the perception of femininity and is a safe procedure.

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

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.

Probiotic bacteria improved skin and hair health in aged mice.

Oxidative stress contributes to hair graying and loss as we age.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.

Different PIN proteins affect plant root hair growth by changing how auxin is transported.

Wnt and Notch signaling help wound healing by promoting cell growth and regulating cell differentiation.

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

Manipulating the catagen and telogen phases of hair growth could lead to treatments for hair disorders.

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

Skin surface lipids are important for skin health and altering them could help prevent aging and treat skin conditions.

Lampreys have a functional vitamin D receptor that may help detoxify harmful substances.

FGF signaling is a promising target for developing treatments for wounds, metabolic diseases, and cancer.

A genetic region near the PAX1 gene is linked to a higher risk of scoliosis in females.

A mother's PPARγ is crucial for preventing harmful milk that can cause inflammation and growth problems in babies.

Hair ages due to genetics and environmental factors, leading to graying and thinning, with treatments available for some conditions.

A cluster of sulfur-rich hair protein genes was found on chromosome 17.
