Scientific Literature and Research regarding Stem Cells In Orthopaedics

There are three types of stem cells: embryonic, induced pluripotent, and adult stem cells. Adult stem cells are used in regenerative medicine around the world.

Adult stem cells come in two “flavors”: hematopoietic, which form blood products of the human body and mesenchymal, which are responsible for musculoskeletal tissue repair [1,2]. They are both important components of the Regenexx SD stem cell treatments that Dr Stiene performs. Together they work to help create or maintain a blood supply to the treated area, which is critical for healing, as well as be responsible for regeneration.

Adult mesenchymal stem cells (MSCs) work by stopping the natural breakdown of tissue by degradative or “catabolic” proteins and over time reversing the process to stimulate healing [1,2,3]. This makes it a beneficial treatment option for those with mild to moderate osteoarthritis [4].

There are several different ways to harvest MSCs. Dr Stiene uses bone marrow aspirations as this is a frequently used method of stem cell harvesting. It is a safe, low pain, same day procedure, with an easily prepared product. This product requires minimal manipulation and is in compliance with the FDA [3]. It is also autologous which means that their use has a low risk of infection or rejection. This makes it a safe option for those suffering from mild to moderate osteoarthritis [5].

Furthermore; manipulation of harvested stem cells have been shown to be beneficial in cases of very advanced degenerative joint disease [6,7,8]. This is a common practice in other countries but is an area where American medicine is lacking as its practice is restricted by the FDA [9].  Regenexx Cayman, in the Cayman Islands, offers this option to those seeking this form of treatment. You can find more information on their website listed below.
