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.

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

The article concludes that better understanding gene regulation related to seasonal changes can offer insights into the mechanisms of seasonal timing in mammals.

Topical drugs and near-infrared light therapy show potential for treating alopecia.

Kennedy's disease leads to muscle weakness without a cure, but exercise and managing symptoms may help patients live a normal lifespan.

Baicalin helps hair growth by activating specific cell signals and pathways.

The conclusion suggests that PCOS may persist due to genetic traits that, while harmful for female fertility, could have provided survival and reproductive benefits to males.

Hormones and genes affect hair growth and male baldness.

Certain gene variations might help protect against insulin resistance and glucose intolerance in people with Polycystic Ovary Syndrome.

The R343H mutation in the VDR gene causes vitamin D-resistant rickets with alopecia by impairing specific gene activity.
