Abstract: Mesenchymal stem cells (MSCs) secretome: a good candidate for medical biotechnology? Medical biotechnology is currently defined as the application of biotechnological tools for producing multiple technologies and products to health care, becoming an important bridge between different fields, namely neuroscience, regenerative medicine, pharmacology and bio-engineering (Pham, 2018). The use and manipulation of stem cells can potentially represent a medical biotechnology breakthrough that brings regenerative medicine to a new era. Actually, over the last decade, the use of stem cells has remarkably been proposed as a regenerative tool, and within it, MSCs have emerged as a promising therapeutic option. As a consequence, they currently represent an effective tool in the treatment of several diseases due to their tissue protective and reparative mechanisms (Phelps et al., 2018). Indeed, MSCs are the most frequently stem cell population used in clinical trials (as of the end of 2018, a total of 861 trials were registered according to the US National Institute of Health – https://clinicaltrials.gov), presenting key advantages such as (1) be isolated from a patient and used for autologous transplantation; (2) not divide uncontrollably and form teratomas; and (3) have the capability to differentiate into multiple lineages (Kusuma et al., 2017). The initial therapeutic rationale of the use of MSCs in regenerative medicine as mostly attributed to their capability of homing to injury sites and differentiates into different cell types, leading to tissue repair. Although promising, this theory was revisited at the beginning of the 20th century when, for the first time, Gnecchi and colleagues revealed that MSCs mediated its therapeutical effects by the secretion and release of trophic molecules, nowadays known as secretome (Gnecchi et al., 2005). Indeed, cell tracking analysis has revealed that when transplanted, MSCs (and stem cells in general) do not commonly become a part of the injured site, whereby accumulating pieces of evidence indicate that the secretome is considered the primary attribute of MSC-mediated repair and regeneration (Teixeira et al., 2013).
