Conditioned Media from Mesenchymal Stem Cells as a Basis for Therapy

When culturing any type of cell, the culture media contents come to reflect the secreted molecules and extracellular vesicles of that cell type - what is called "conditioned media". It is a snapshot of the communications produced by the cell type in its current state. First generation stem cell therapies, in which the transplanted cells die rather than integrate with tissues in any useful number, influence health via the effects of their secretions and vesicles on native cells. It is much easier to build therapies based on the contents of the media rather than it is to transplant the cells themselves, from the perspective of storage, readiness, consistency of production, and so forth, and so this is the direction that the clinical industry has been taking for some years. Of course, nothing involving cells is ever simple, as this review notes. Recently published studies suggest that the paracrine substances released by mesenchymal stem cells (MSCs) are the primary motive behind the therapeutic action reported in these cells. Pre-clinical and clinical research on MSCs has produced promising outcomes. Furthermore, these cells are generally safe for therapeutic use and may be extracted from a variety of anatomical regions. Recent research has indicated, however, that transplanted cells do not live long and that the advantages of MSC treatment may be attributable to the large diversity of bioactive substances they create, which play a crucial role in the control of essent...
