Researchers were looking into stem cells and skin regeneration writ large, a complex and ever-evolving area of development. In the study, led by Elaine Fuchs, Ph.D., the Rebecca C. Lancefield professor at the Rockefeller University, scientists confirmed that stem cells have the ability to instruct other stem cells to regrow new skin. But the totally new concept they found was the connection to the lymphatic system. “Lymph is a fluid that has no color, and it contains white blood cells, which are our key immune cells. Lymph covers the tissues in our body, and it has its own drainage system, which is called the lymphatic system,” explains mbg Collective member and integrative physician Marvin Singh, M.D. “There is an intricate system of lymph capillaries (basically small drainage pipes) that collects all the fluid that occupies the spaces between different tissues in the body. Those little capillaries connect to larger pipes, called lymph vessels, which lead to lymph nodes.” The lymphatic system, he goes on to explain, acts as an internal cleaning system for our body—clearing out any buildup of toxins, helping our immune system, and balancing the fluid in our body. And these niches are all interconnected by, you guessed it, the lymphatic system. They discovered that surrounding each niche was an intertwined network of lymphatic capillaries connecting all of the stem cell niches. These hair-follicle stem cells were able to act as an “on-off” switch for drainage, controlling what fluid and cells were in the surrounding area, and ultimately, regeneration across more tissue. And if scientists are able to tap into this complex system, maybe they’ll be able to encourage growth across areas of the scalp that need it most, like thinning or bald spots. There’s much more to be done post-research, but it’s an interesting development. And just another example of how important a healthy lymphatic system is.
