If you could obtain the needed anasthetics and equipment, could you aspirated your own bone marrow for the purpose of obtaining mesemchymal stem cells? The problem is that the preferred aspiration site, the iliac crest, would be very difficult to reach on one's own. You could reach your own proximal tibia, but my understanding is that the marrow in that region is not as rich in cells. I would not be willing to try the sternum. Anyone with medical expertise, please state your analysis. Thank you.
