In cities like Beverly Hills or New York a prospective patient may only need to drive some 20 or 30 minutes from the center of town to find such a treatment.
This vast stem cell market has boomed in recent years, particularly for orthopedic applications such as easing joint pain or for facelifts and other cosmetic procedures.
