Are intracardiac fibroblasts , but not bone marrow derived cells , the origin of myofibroblasts in myocardial infarct repair?
The findings in this study suggest that proliferating myofibroblasts in infarcted myocardium are derived from resident fibroblasts rather than circulating precursor cells of bone marrow origin.
This case illustrates the importance of considering PAN in the differential diagnosis of renal infarction with inflammatory syndrome and shows that spontaneous remission of renal PAN can occur. .
