See regenerative medicine can be a great field for you. If you want to do research in future then you can obviously go for it. It will enable you to work on a vast field of Clinical Medicine and you can discover new ways to combat the diseases like Cancer etc. SO its no doubt a great career choice but you should follow it only if you are interested in research or else it will not be as lucrative as it would be for research in terms of your career.

I hope this answer helps. All the very best for your future endeavors!
