Despite a certain unavoidable variability in islets preparations and the limited availability of human islets in particular, it should be underlined that the findings of our study are fairly consistent, with regard to both the similarity of the results between rat and human islets and the effects of the protection exerted by the vegetal compounds on the measured parameters.
We interpret our results regarding the origin of certain variability components.
