Sick one, no, they used what has been medical waste for the last 5,000 years to help this man and now many, many more. Placenta from live births are processed to remove their inner most lining. That lining contains growth factors and adult stem cells. Those stem cells, now this is a big word, so hold on, mesenchymal stem cells (MSCs) are able to become whatever is needed by the host body, that is bone, connective tissue, stromal (muscle) tissue, lipid (fat), even skin. Crawling from under your stone, you may find that this can even improve lives of folks you know. How bout that.
