The biggest detail, you neglected to mention, is that the quantity in marrow is very small. Plus, those stem cells are not "potent". They have a limited range as to what they can become.

If you mean the marrow inside the bone will regenerate, then yes, that is correct.
If you're saying that a bone will grow back if it's removed, science totally disagrees. A removed bone is gone, permanently. And a removed rib will not "regrow" into a human, it will just die. At even a rediculous best case scenerio, the rib will just grow more rib.
