Regenerative Medicine and Surgery is a rapidly expanding branch of translational research in tissue engineering, cellular and molecular biology. To date, the methods to improve cell intake, survival and isolation need to comply with a complex and still unclear regulatory frame, becoming everyday more restrictive and often limiting effectiveness and outcome of the therapeutic choices. Thus, the author developed a novel regenerative strategy, based on the synergic action of several bio-active components, called the Bio-Active Composite Therapies (BACTs) to improve grafted cells intake and survival in total compliance with the legal and ethical limits of the current regulatory frame. The rationale at the origin of this new technology is based on the evidence that cells need supportive substrate to survive in vitro and this observation, applying the concept of translational medicine, is true also in vivo. Many different sources have been used in the past for MSCs, molecules and growth factors (GF) isolation and extraction, but the Adipose Tissue and its Stromal Vascular Fraction (SVF) definitely remains the most valuable, abundant, safe and reliable. Bio-Active Composite Mixtures (BACMs) are tailor-made injectable “cocktails” containing several bio-active components to support cells survival and induce a strong regenerative response in vivo by stimulating the recipient site to act as an in-situ real Bioreactor. In this article, the author analyze the main causes of cell’s death and the strategies for preventing it, and outline all the technical steps for preparing the main components of BACMs and the different mixing modalities to obtain the most efficient regenerative action on different clinical and pathological conditions in several surgical specialties. Orthopedic Surgery is definitely the one that most can benefit of these new therapeutic strategies. The final part of this work is anticipating the logical and sequential evolution toward other fundamental technical steps for further supporting and enhancing the most efficient regenerative activity.
