Regenerative medicine has rapidly evolved, due to progress in cell and molecular
biology allowing the isolation, characterization, expansion, and engineering of
cells as therapeutic tools. Despite past limited success in the clinical
translation of several promising preclinical results, this novel field is now
entering a phase of renewed confidence and productivity, marked by the
commercialization of the first cell therapy products. Ongoing issues in the field
include the use of pluripotent vs. somatic and of allogenic vs. autologous stem
cells. Moreover, the recognition that several of the observed beneficial effects
of cell therapy are not due to integration of the transplanted cells, but rather
to paracrine signals released by the exogenous cells, is generating new
therapeutic perspectives in the field. Somatic stem cells are outperforming
embryonic and induced pluripotent stem cells in clinical applications, mainly
because of their more favorable safety profile. Presently, both autologous and
allogeneic somatic stem cells seem to be equally safe and effective under several
different conditions. Recognition that a number of therapeutic effects of
transplanted cells are mediated by paracrine signals, and that such signals can
be found in extracellular vesicles isolated from culture media, opens novel
therapeutic perspectives in the field of regenerative medicine.
