Our bodies are made up of trillions of cells that all work together to keep us alive. Cells are the basic building blocks of all living things – including humans – and each cell serves a very specific function in our body. During development, stem cells divide and create more cells that specialize to serve a specific purpose. Once their function is fully developed these cells are often referred to as “differentiated” cells since each is established in its unique role and has a very specialized function. Just like our bodies, our cells age too and as the process of aging takes hold, our cells do not perform as efficiently and eventually die off. Regeneration, or the replacement, of these cells also decreases with age.
