The hypothesis suggests that PCOS may start early in life due to genetic and environmental factors, influencing future reproductive and metabolic problems.

Some wound-healing cells can turn into fat cells around new hair growth in mice.

The study found that in Latin America, ancestry varies by location, influences physical traits, and affects how people perceive their own heritage.

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.

More dermal papilla cells in hair follicles lead to larger, healthier hair, while fewer cells cause hair thinning and loss.

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

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.

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

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

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

Periodontal ligament stem cells show promise for regrowing tissues but require more research for safe, effective use.

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.

Lignans and neolignans from plants may help protect against various health issues, including cancer and heart disease.
