How do cardiomyocytes gain nourishment
WebPrevious studies that tried to regenerate heart muscle with stem cells in rodents only used cardiomyocytes - heart muscle cells – but they weren’t successful as cells often died quickly. In the new research, researchers used epicardial cells - supportive cells from the outer wall of the heart – to supplement grafts of cardiomyocytes in rats. WebIn this review, we walk through the history of scientific inquiry into cardiomyocytes, and then we examine the core features of cardiomyocytes as detailed in modern definitions. …
