The adipose tissue of a human is widely known to be a rich source of adult stem cells. These stem cells are prolific for having the ability to differentiate into various cell lineages. 

The extraction process, generally, begins with elective liposuction to extract the adipose tissue. Adipose derived cells have been used with PRP and/or BMAC in the treatment of many musculoskeletal and vascular disorders. Adipose derived stem/stromal cells are similar but not identical to bone marrow cells.
