Introduction
Rap1, a member of Ras superfamily of small GTP‐binding proteins, is involved in cardiovascular biology in numerous ways. It is an evolutionary conserved regulator of adhesion, polarity, differentiation and growth.
Aims
Our aim was to analyze Rap1‐activated rat bone marrow mesenchymal stem cells (MSCs) for their potential role in adhesion and cardiac differentiation.
Methods
Myocardial infarction (MI) was produced in Sprague Dawley (SD) rats through occlusion of the left anterior descending coronary artery. MSCs were treated with 8‐pCPT‐2′‐O‐Me‐cAMP (CPT) to activate Rap1. Normal (untreated) and CPT‐treated MSCs were transplanted through intramyocardial injection in respective groups. Cardiac function was assessed by echocardiography at 2 and 4 weeks after cell transplantation. Histological analysis was performed to observe changes at tissue level.
Results
Homing of CPT‐treated MSCs was significantly (***P |
