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.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.

Foxp3 is crucial for regulatory T cell function, and targeting these cells may help treat immune disorders.

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

Janus kinase inhibitors are promising treatments for autoimmune skin diseases like eczema and psoriasis.

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