A monophasic dose-effect romance is Formerly documented with cells of mesenchymal origin sent transendocardially in cardiomyopathic ventricles. This features a dose-escalation review the place the very best dose (a hundred and fifty million cells) manufactured biggest reward.nine However, inverse or ‘U-condition’ relationships have also been reported.
