Why does Sparrow use liposuction fat rather than bone marrow as a source of stem cells?

Bone marrow sampling (a somewhat uncomfortable procedure) yields approximately 5,000 – 60,000 cells that are then cultured over several days to perhaps a few million cells prior to deployment (injection into the patient). Recent advances in stem cell science have made it possible to obtain high numbers of very excellent quality multi-potent (able to form numerous other tissues) cells from a person’s own liposuction fat. Sparrow uses technology acquired from Asia to process this fat to yield approximately five hundred thousand to one million stem cells per cc of fat, and therefore, it is possible to obtain as many as 10 to 40 million cells from a single therapy. These adipose-derived stem cells can form many different types of cells when deployed properly including bone, cartilage, tendon (connective tissue), muscle, blood vessels, nerve tissue, and others.
