The effect of bone marrow- and adipose tissue-derived mesenchymal stem cell transplantation on myocardial remodelling in the rat model of ischaemic heart failure.

This study aimed to investigate the effect of bone marrow- and adipose tissue-derived mesenchymal stem cell (BM-MSC and AD-MSC respectively) transplantation on left ventricular function and infarct area (IA) in the rat model of ischaemic heart failure. In anaesthetized Wistar rats, the left coronary artery (LCA) was occluded for 40 min with subsequent reperfusion for 7 days. Seven days following surgery, the animals with LCA occlusion/reperfusion were randomized into three groups: (i) Controls received intramyocardial injection of vehicle at three different locations within the peri-infarct zone, (ii) BM-MSC: cells were injected in the same way as in previous group (10(6) ), (iii) AD-MSC: using the same protocol as used in the BM-MSC group.

Isoflurane and other commonly used anaesthetics do not protect the isolated buffer perfused mouse heart from ischemia-reperfusion injury.

1. Some anaesthetic agents such as barbiturates and opioids possess cardioprotective properties in rats, rabbits, dogs and pigs. The purpose of this study was to evaluate the effects of some commonly used anaesthetic agents (pentobarbital, isoflurane and a mixture of midazolam, fentanyl and fluanisone) on the tolerance of the isolated mouse heart to ischaemia-reperfusion injury.
