This symposium reviewed various topics in stem cell research related to skin biology, including mechanisms of skin regeneration, tumorigenesis, and pathways influencing melanoma stem cell behavior, but it reported no new clinical results.

This study suggests that Demodex mites might universally inhabit adult humans, with a phylogenetic analysis indicating potential undiscovered lineages of the D. brevis species based on geographic differences.

Mammalian organs regenerate using stem cells and cell plasticity, but this ability declines with age.

This review discusses the distinct roles and surprising developmental flexibility of multiple somatic stem cell types in tissue maintenance and repair, reporting no new results but highlighting emerging questions about their regulation and origins.

This study found that glycolytic metabolism and lactate production are crucial for hair follicle stem cell activation, and manipulating these processes can stimulate the hair cycle.

This study found that Hoxc gene expression can reprogram mesenchymal dermal papilla cells, enhance epithelial stem cell regenerative potential, and promote region-specific hair follicle regeneration through Wnt signaling.

This study found that rete ridge morphogenesis in mammalian skin is directed by a BMP-dependent developmental program, which is evolutionarily distinct from other known pathways controlling the development of hair follicles, sweat glands, and fingerprint ridges.
