Stem-cell controlled network of lymphatic capillaries around hair follicles involved in tissue regeneration
Your skin has the natural ability to do what some miracle creams promise: rejuvenate and regenerate. Tiny stores of stem cells – starter cells able to develop into any form of brand new cell – are stashed all over the skin, providing a constant replenishment service. How exactly these cells dictate regeneration isn’t understood, but a new study has identified a molecular management tool used by stem cells to coordinate between the stores. It also revealed that special vessels called lymphatic capillaries form a complex network between the pools of cells, which sit at the base of each hair follicle. Stem cells in the follicles (pictured, after the researchers rendered the skin transparent to view the network) secrete molecules to control the surrounding environment and synchronise growth across the skin – a discovery that could provide a new approach to tackling wound-healing defects and even hair loss.
BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
BPoD is also available in Catalan at www.bpod.cat with translations by the University of Valencia.
