The document concludes that the exact way alcohol causes harm to fetal development is unknown, but it significantly affects nutrient transport to the fetus and a safe level of alcohol during pregnancy is not determined.

The conclusion is that accurate diagnosis of different types of hair loss requires good teamwork between skin doctors and lab experts.

Scientists found a new, less invasive way to study body clocks using hair cells, which shows shift workers' body clocks don't match their lifestyles.

CDP is crucial for lung and hair follicle cell development.

Stem cell niches support, regulate, and coordinate stem cell functions.

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.

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

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

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

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Low oxygen conditions increase the hair-growing effects of substances from fat-derived stem cells by boosting growth factor release.

Different types of stem cells and their environments are key to skin repair and maintenance.

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

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.

Fat cells in the skin help start healing and form important repair cells after injury.

Understanding how cells die in the skin is important for treating skin diseases and preventing hair loss.

Potassium channel openers are effective in treating heart conditions, high blood pressure, pulmonary diseases, bladder issues, and hair loss, but more selective drugs are needed.

The hydrogel with a 1:3 ratio of hydroxyethyl cellulose to hyaluronic acid is effective for delivering drugs through the skin to treat acne.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

The paper concludes that the 1982 criteria for diagnosing systemic lupus erythematosus need updating to improve accuracy and involve dermatologists in the process.

Fetal wound healing changes with development, affecting inflammation and collagen, which may influence scarring.

We need more research to better understand human hair follicle stem cells for improved treatments for hair loss and skin cancer.

UV radiation can help sterilize wounds and promote healing but requires careful use to avoid damaging cells.

MicroRNA-214 is important for skin and hair growth because it affects the Wnt pathway.

Notch/CSL signaling controls hair follicle differentiation through Wnt5a and FoxN1.

New nanocomposites with copper show promise for healing burn wounds and regenerating skin.

Wnt signaling helps control how brain stem cells divide and is important for brain repair after injury.
