Synthetic silicates, which are composed of simple or complex salts of silicic acids, are used in a wide range of industrial and consumer applications, including food additives, glass and ceramic filler materials, and anti-caking agents. Today, researchers at the Brigham and Women's Hospital (BWH) announced another potential application, generating bone from stem cells. The BWH researchers have discovered that synthetic silicate nanoplatelets, also known as layered clay, can induce

Unlike most vertebrates which can replace lost teeth through their entire lives, humans come with only two sets, baby teeth and adult teeth, then they simply lose the ability for tooth renewal.. However, a new study on alligators by researchers at the Keck School of Medicine, University of Southern California (USC) may someday allow doctors to stimulate tooth regeneration in humans as well.Read More

It's a well known fact that exercise induces stem cells in the hippocampus, a important brain area, to become neurons, a process known as neurogenesis However, up until now little was known about the deeper mechanisms involved in this process. Now, a new study on mice by researchers at the Max Delbrück Centre (MDC), Berlin-Buch reveals that serotonin plays a direct role in exercise-induced neurogenesis.Read More

Yesterday, the Arizona Pain Stem Cell Institute announced a new, non-randomised trial involving stem cell injections. The study will evaluate the safety and efficacy of injections containing amniotic stem cells combined with high concentrations of hyaluronic acid and growth factors in patients with "back and neck pain along with pain in the shoulder, knee, hip and sacroiliac joint".
