Yes,there are many types of adult stem cells. The most common is known as a hematopoetic stem cells (HSC-CD 34+). While these are easy to obtain from IV mobilized blood (where a special medicine is given to the patient first to push these cells out of the bone marrow) or bone marrow and are very plentiful. Outside of a handful of cardiac and vascular applications, they are not well studied as being effective in treating a broad range of diseases. Despite this, the vast majority of what you see being billed as “stem cells” from bone marrow (where the cells are injected the same day as collected) are these less useful cells. The type of adult stem cell that is most often seen in research as being associated with orthopedic tissue repair is a mesenchymal stem cell (MSC). MSCs can’t generally be harvested from blood. Fat tissue contains many MSCs, but these are distant cousins to the type obtained from bone marrow and aren’t as useful for orthopedic applications.
