CD117+AMNIOTIC FLUID STEM CELLS VARY THEIR IMMUNE REGULATORY PROPERTIES ACCORDING TO GESTATIONAL AGE

increased the production of IL-6, COX2, CD54 and CD274. In conclusion, multiparametric flow cytometry enables the simultaneous analysis of intracellular and surface markers to i) determine the licensed status of different batches of MSCs, ii) measure the level of immunomodulatory activity, iii) identify the source of cytokines in co-culture systems and iv) define biomarkers predicting MSC potency.
