Stem Cells Grow Bone and Cartilage Tissue
A new class of clay nanoparticles that can direct stem cells to become bone or cartilage cells. Human stem cells have shown potential in medicine as they can transform into various specialized cell types such as bone and cartilage cells. The current approach to obtain such specialized cells is to subject stem cells to specialized instructive protein molecules known as growth factors. However, use of growth factors in the human body can generate harmful effects including unwanted tissue growth, such as a tumor.
