Apparently from what im reading it is "all" types of stem cell procedures, but I am not a doctor and I could be wrong.
https://en.wikipedia.org/wiki/Mesenchymal_stem_cell Mesenchymal stem cells are multipotent stromal cells that can differentiate into a variety of cell types, including osteoblasts (bone cells), chondrocytes (cartilage cells), myocytes (muscle cells) and adipocytes (fat cells which give rise to marrow adipose tissue).
