If Stem Cells Can Be Used to Enlarge Breasts, Can It Be Used to Enlarge Bone As Well?

Theoretically speaking, stem cells can be turned into any cell, but would it be practical? By enlarging or modifying the bone structure I mean, for example, a weak receding chin turn into a projecting strong square chin. Or potentially modifying the length of limbs for height increase. Even turning a large low bridge convex nose in to a tall straight proportioned nose. I'm really speaking of the future when I talk about this. Stem cells comes off to me as revolutionary in cosmetics.
