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.

Pectin biosynthesis is essential for the growth of cotton fibers and Arabidopsis root hairs.

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

Androgens can cause hair growth in some areas and hair loss on the scalp.

K_ATP channel gene mutations are linked to heart diseases, but more research is needed to understand the connection and treatment potential.

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.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Probiotic bacteria improved skin and hair health in aged mice.

Mice hair growth patterns get more complex with age and can change with events like pregnancy or injury.

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.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

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

The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

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

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.

Formyl-peptide receptor agonists could be new anti-inflammatory drugs.
