Mutations in the SRD5A3 gene cause a new type of glycosylation disorder by blocking the production of a molecule necessary for protein glycosylation.

Hair loss and aging are caused by the breakdown of a key protein in hair stem cells.

Melanocyte stem cells in hair follicles are key for hair color and could help treat greying and pigment disorders.

The skin is a complex barrier for drug penetration, but understanding its structure and interactions can improve drug delivery methods.

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

Male and female bodies respond differently to stress, influenced by hormones and development stages, with implications for stress-related diseases.

Regulatory T-cells are important for healing and regenerating tissues in various organs by controlling immune responses and aiding stem cells.

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.

Blocking JAK-STAT signaling can lead to hair growth.

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

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

RNAi-based biopesticides could be safe and effective for pest control with careful development and risk assessment.

The enzyme 25 Hydroxyvitamin D 1 α-Hydroxylase is essential for healthy skin and recovery after skin damage.

Masculine facial features may not reliably indicate heritable health, and more research is needed.

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.

MicroRNA-302 helps improve the conversion of body cells into stem cells by blocking NR2F2.

Vitamin D has potential benefits for cancer prevention, heart health, diabetes, obesity, muscle function, skin health, and immune function, but clinical results are mixed and more research is needed.

Melatonin helps regulate hair growth and protects the hair follicle from stress.

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.

Nerves and chemicals in the body can affect hair growth and loss.

Growth factors and cytokines are important for hair growth and could potentially treat hair loss, but more research is needed to overcome challenges before they can be used in treatments.

A WNT10A gene mutation leads to ectodermal dysplasia by disrupting cell growth and differentiation.

Exosomes from dermal papilla cells can help grow hair and might treat hair loss.

Activating the Wnt/β-catenin pathway could lead to new hair loss treatments.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.

NF-κB is crucial for zebrafish heart repair, affecting heart cell growth and repair processes.

Animal models have helped understand hair loss from alopecia areata and find new treatments.

The document concludes that minoxidil and finasteride are proven for hair growth, herbal remedies show promise, but more research is needed to confirm their effectiveness.

Activin helps skin growth and healing mainly through stromal cells and affects keratinocytes based on its amount.
