A new hair transplant method showed promising results and a study found how deep a CO₂ laser can penetrate skin.

Shorter daylight increases hair growth in Cashmere goats.

The document concludes that there is no agreed-upon best method for measuring drug delivery within hair follicles and more research is needed to validate current techniques.

Nanocarriers could improve how drugs are delivered through the skin but require more research to overcome challenges and ensure safety.

Targeting hair follicles can effectively promote hair growth and treat hair disorders.

miR-22, a type of microRNA, controls hair growth and its overproduction can cause hair loss, while its absence can speed up hair growth.

The document concludes that local flaps are effective for reconstructive surgery in the head and neck, offering good skin match and function.

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.

Normal skin cell renewal doesn't need RAR signaling, but vitamin A-related skin thickening does.

Overexpressing Dsg3 in mice skin causes excessive cell growth and abnormal skin development.

Skin-derived precursors in hair follicles come from different origins but function similarly.
