14 Cell-cost-free products mimicking the paracrine effects of cell-primarily based therapies can likely achieve standardized dosing reflecting extra intently the pharmacology of modest chemical molecules. One more avenue for posological standardization contains utilization of cyto-engineering and/or allogeneic techniques to beat mobile-to-mobile variability in regenerative potency inherent to autologous mobile therapies. These methods supply the consistency required to streamline the comprehension of dosage parameters for regenerative goods. The trail to adoption in cardiology care15 will Consequently mandate a transdisciplinary hard work bringing collectively multiple specialties to determine validated posology for regenerative therapy.
