Human Adipose-Derived Mesenchymal Progenitor Cells (haMPC)
Adult mesenchymal stem cells can currently be isolated from a variety of adult human sources, such as liver, bone marrow, and adipose (fat) tissue. The advantages in using adipose tissue (as opposed to bone marrow or blood) are that it is one of the richest sources of pluripotent cells in the body, the easy and repeatable access to fat via liposuction, and the simple cell isolation procedures that can begin to take place even on-site with minor equipment needs. The procedure we are testing for KOA involves extracting a very small amount of fat using a minimally invasive extraction process which takes up to 20 minutes, and leaves no scarring. The haMPC cells are then processed and isolated on site, and injected intra-articularly into the knee joint with ultrasound guidance.
These haMPC cells are capable of differentiating into bone, cartilage, tendon, skeletal muscle, and fat under the right conditions. As such, haMPCs are an attractive focus for medical research and clinical development. Importantly, we believe both allogeneic and autologously sourced haMPCs may be used in the treatment of disease. Numerous studies have provided preclinical data that support the safety and efficacy of allogeneic and autologously derived haMPC, offering a choice for those where factors such as donor age and health are an issue.
