There is a lot to learn about regenerative biologics. This includes where they come from, what they consist of, how they work in the body. The field has come a long way in a very short time. You don't need to become a basic scientist to offer these procedures, but you should have a very good basic understanding biologics including autologous and allogeneic sources. Patients often ask questions about the biologics, so it is critical to be able to properly answer. This section will provide you with an excellent understanding regarding regenerative biologics and the associated stem cells, growth factors, cytokines, exosomes and the additional supporting "cast and crew". We have also included a separate presentation on exosomes, as they are the "rising star" in the field of regenerative medicine. The last presentation includes an overview of supplements to optimize stem cell therapy outcomes.
