Lambs' skin showed similar but more severe responses to a second orf virus infection, involving immune cells and new skin formation.

Wound healing is a complex process involving different cells and stages, leading to scar tissue formation and strength increase over time.

Skin cancer involves complex mechanisms, risk factors, and can be potentially prevented with strategies like dietary changes and certain compounds.

Macrophage iron release is crucial for hair growth and wound healing.

Activins and follistatins, part of the TGFβ family, are crucial for hair follicle development and skin health, affecting growth, repair, and the hair cycle.

Skin and hair can regenerate after injury due to changes in gene activity, with potential links to how cancer spreads. Future research should focus on how new hair follicles form and the processes that trigger their creation.

S100A6 protein is linked to disease progression, especially in cancers.

In vivo lineage labelling is better than in vitro methods for identifying and understanding stem cells.

Menopause causes significant changes in the vaginal introitus, but less so in the labia majora, which may lead to symptoms of vaginal atrophy.

Birth control pills increase certain receptor activities in female gerbil prostate glands and can lead to prostate changes.

Spiny mice regenerate skin better than laboratory mice due to larger hair bulges, more stem cells, and different collagen ratios.

Basonuclin 1 (BNC1) helps skin cells multiply and move, which is crucial for wound healing.

African spiny mice can regenerate skin and hair after wounds due to specific tissue mechanics.

5-alpha reductase inhibitors might worsen lung recovery in COVID-19 patients, suggesting a pause in their use.
