Stem cells aren't the answer yet for COPD. They've made remarkable progress in their use in other diseases, but not for lung diseases. The lungs are some of the most complex organs in the body and we don't yet know enough about what cells are required to do what tasks to be able to target stem cells. Current treatments are pretty much the equivalent of snake oil and the people who offer them are interested in your money, not in your lungs. I'm sorry you got caught in that web; it's easy and you're not alone.

I have gave up on stem cell. Had a treatment done with no good result

I’m starting the testing process now

I have not had a transplant, but if I were at a point where that would be an option, I would be sure to find a good center where they've done successful transplants before, and get tested. You can't just show up and say you want a TX, there's a whole process to first get approved for one and get on the list and then it's a waiting game. The first step is to get tested, and you can be assured that it will be one of the most thorough physical tests you've ever had and you can learn a lot about your COPD and pretty much everything else that might ail you if you ask lots of questions. Be aware that they will also do their very best to learn everything there is to know about you from your family relationships, to your psychological profile and your financial resources. It's probably more thorough than if a Democrat were clearing a Republican for office or vice versa. So it's pretty invasive in that sense. However, you need to be forthcoming if you're really interested in a TX, because if you're not, that could disqualify you. Once you've completed the evaluation, you will know just about everything there is to know about a TX and you will be able to make an informed decision about whether you're interested or not.
