Bob told me that autologous, fat-derived stem cells had significant clinical limitations. As he explained it, our tissues and organs go through a continuous process of renovation and renewal, a process naturally driven by our stem cells. Here’s the catch: From the moment we’re born, our stem cell reservoir starts drying up. It’s a process called “stem cell exhaustion,” and it’s believed to be one of the main causes of aging. As we get older, some of our stem cells get used up. Most of them stick around but lose the ability to repair or replace our damaged tissues.
